Description

The 667 actuator (figure 1) and the 667-4 actuator are reverse-acting, spring-opposed diaphragm actuators. They

provide automatic operation of control valves. The 667 actuator provides 76 mm (3 inches) maximum actuator travel.

The 667-4 actuator provides 102 mm (4 inches) maximum actuator travel. Both actuators position the valve plug in

response to varying pneumatic loading pressure on the diaphragm. Figure 2 shows the operation of these actuators.

A 667 or 667-4 actuator can be furnished with either a top-mounted or a side-mounted handwheel assembly. A

top-mounted handwheel assembly is normally used as an adjustable down travel stop. (A down travel stop limits

actuator travel in the down direction [when the stem is traveling out of the actuator]. Travel in the up direction is when

the stem is traveling into the actuator.) A side-mounted handwheel assembly is normally used as an auxiliary manual

actuator. The side-mounted handwheelcanalsobeusedasanadjustableupordowntravelstop.Casing-Mounted

adjustable up or down travel stops are also available on this actuator.

Note

If repeated or daily manual operation is expected, the actuator should be equipped with a side-mounted handwheel rather than a

casing-mounted travel stop or top-mounted handwheel. The side-mounted handwheel is designed for more frequent use as a

manual operator.

WARNING

To avoid personal injury or damage to equipment that may result in the malfunction of the control valve or loss of control

of the process caused by excessive pressure, do not exceed the Maximum Pressures listed in table 1. Refer to the Maximum

Pressure Limitations section.

Maximum Pressure Limitations

The casing and diaphragm of 667 actuators are pressure operated. This air pressure provides energy to compress the

spring, to stroke the actuator, and to seat the valve. The following explanations describe the maximum pressure limits

for an actuator. Refer to the nameplate or table 1 for maximum values for your actuator.

Instruction Manual

D100310X012

667 Size 30-76 and 87 Actuators

November 2013

DMaximum Casing Pressure for Actuator Sizing: This is the maximum pressure that can be applied at less than full

travel of the actuator. If this stroking pressure is exceeded before the upper diaphragm plate contacts the travel

stop, damage to the stem or other parts might result.

DMaximum Excess Diaphragm Pressure: Additional pressure may be added when the actuator is at full travel. If the

Maximum Excess Diaphragm Pressure is exceeded, damage to the diaphragm or diaphragm casing might result.

Because the actuator has traveled its specified travel, and the diaphragm head is physically stopped from movement,

the energy from any additional air pressure is transmitted to the diaphragm and diaphragm casings. The amount of air

pressure that can be added once the actuator has traveled to the stops is limited by the resultant adverse effects that

may occur. Exceeding this limiting factor could result in leakage or casing fatigue due to the deformation of the upper

diaphragm casing.

DMaximum Diaphragm Casing Pressure: If the Maximum Diaphragm Casing Pressure is exceeded, damage to the

diaphragm, diaphragm casing, or actuator might result.

Installation

WARNING

Always wear protective gloves, clothing, and eyewear when performing any installation operations.

Check with your process or safety engineer for any other hazards that may be present from exposure to process media.

If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this

instruction manual.

Key number locations are shown in figures 6, 7, and 8, unless otherwise noted. Also, refer to figure 3 for location of

parts.

CAUTION

To avoid parts damage, do not use an operating pressure that exceeds the Maximum Diaphragm Casing Pressure (table 1)

or produces a force on the actuator stem greater than the Maximum Allowable Output Thrust (table 1) or the Maximum

Allowable Valve Stem Load.

DValve/Actuator Assembly: If the actuator and valve are shipped together as a control valve assembly, it has been

adjusted at the factory, and may be installed in the pipeline. After installing the valve in the pipeline, refer to the

Loading Connection procedures.

DActuator Mounting: If the actuator is shipped separately or the actuator has been removed from the valve, it is

necessary to mount the actuator on the valve before placing the valve in the pipeline. Refer to the following

actuator mounting procedures before placing the valve in service. It is recommended that you perform the Bench

Set Spring Adjustment procedures in this section to confirm that the actuator is adjusted correctly for the valve

travel.

DPositioner: If a positioner is installed, or is to be installed on the actuator, refer to the positioner instruction manual

for installation. During the adjustment procedures, it will be necessary to provide a temporary loading pressure to

the actuator diaphragm.

Instruction Manual

D100310X012

667 Size 30-76 and 87 Actuators

November 2013

DHandwheel Cap: If the handwheel cap (key 247, figures 9, 11, or 17) is not in place, install the cap by pushing it on

by hand until it snaps into place.

Mounting the Actuator on the Valve

CAUTION

The 667 actuator spring load pushes the stem down out of the actuator yoke (see figure 2), and it can come in contact with

the valve stem during actuator mounting.

If the valve stem is allowed to remain in the up position (towards the actuator) during actuator mounting, it can interfere

with the actuator stem during mounting. It is possible to damage valve stem threads or bend the valve stem. Be sure the

valve stem is pushed down (into the valve body), away from the actuator while mounting.

It may be necessary to apply a temporary loading pressure to the actuator to move the actuator stem away from the

valve during installation.

If it is not possible to provide a temporary loading pressure, be very careful when lowering the actuator over the valve

stem to prevent damage to valve stem and threads.

WARNING

When moving the actuator stem with loading pressure applied, exercise caution to keep hands and tools out of the

actuator stem travel path. If the loading pressure is accidently disconnected, personal injury and property damage may

result if something is caught between the actuator stem and other control valve parts.

1. Provide a vise or some other method of supporting the valveandtheweightoftheactuatorduringassembly.For

direct or reverse acting valves, push the valve stem down away from the actuator while mounting the actuator.

2. Screw the stem locknuts all the way onto the valve stem. With the concave side of the travel indicator disk (key 34)

facing the valve, install the travel indicator disk on the valve stem. (Note: The travel indicator disk is not used with

size 87 actuators.)

3. Lift or hoist the actuator onto the valve bonnet:

a. For size 87 actuators: Slowly lower the actuator down onto the valve while guiding the valve stem into the

opening in the end of the actuator stem (see figure 4). Once the actuator is in place, insert the cap screws and

tighten the hex nuts, securing the actuator to the bonnet.

b. Forallothersizeactuators:

DSlowly lower the actuator down onto the valve. As the yoke passes over the end of the valve stem, place the yoke

locknut over the valve stem. (Note: On small size actuators, it may be necessary to remove the indicator disk and

re-installitwhileloweringtheactuatorontothevalvebecausethediskwillnotgothroughtheactuatoryoke

opening).

DContinue to lower the actuator while guiding the valve stem into the opening in the end of the actuator stem until

the actuator is in place (see figure 4).

DScrew the yoke locknut onto the valve bonnet and tighten the locknut.

4. Do not connect the actuator stem to the valve stem at this time. Whenever the actuator is installed on the valve, it

is recommended that you perform the Bench Set Spring Adjustment procedures below, to verify that the actuator is

still adjusted correctly.

Discussion of Bench Set

The bench set pressure values are used to adjust the initial compression of the actuator spring with the valve-actuator

assembly “on the bench.” The correct initial compression ensures that the valve-actuator assembly will function

properly when it is put into service and the proper actuator diaphragm operating pressure is applied.

The bench set values are established with the assumption that there is no packing friction. When attempting to adjust

the spring in the field, it is very difficult to ensure that there is no friction being applied by “loose” packing.

Accurate adjustment to the bench set range can be made during the actuator mounting process by making the

adjustment before the actuator is connected to the valve (see the Spring Verification Procedure).

Spring Verification

Ensure that the actuator diaphragm is at the bottom of its travel as shown in figure 4 and not connected to the valve.

(Note: Some spring compression is required to move the diaphragm to the bottom of its travel.)

Also, provide a certified pressure gauge that will accurately read the diaphragm pressure from 0 through 0.3 bar (5

psig) above the upper operating range pressure marked on the nameplate. Apply loading pressure to the diaphragm.

Stroke the actuator a few times to ensure that the pressure gauge is working correctly, and that the actuator is

functioning properly.

CAUTION

Note

For 667 actuators installed on push-down-to-close (direct acting) valves with fail-close action, the valve plug seat is the limit for

downward travel and the actuator is the limit for upward (away from the valve) movement.

For 667 actuators installed on push-down-to-open (reverse acting) valves with fail-open action, the actuator down stop is the limit

for downward movement, and the valve seat is the limit for upward (away from the valve) movement.

Ensure the correct Spring Verification procedure is followed for the type of valve on which the 667 actuator is installed.

Instruction Manual

D100310X012

667 Size 30-76 and 87 Actuators

For Push Down to Close (Direct Acting) Valves

1. If not already accomplished, push the valve stem down away from the actuator to the closed position.

2. Set the diaphragm loading pressure to 0.3 bar (5 psig) over the upper operating range pressure. The travel stop cap

screw (key 12) should be contacting the upper diaphragm casing.

3. Slowly decrease the pressure towards the upper bench set pressure, as indicated on the nameplate, while checking

for the first linear movement of the actuator stem.

Note

Before turning the spring adjuster on size 70, 76, or 87 actuators, assemble the stem connector around the actuator stem and the

anti-rotating lug on the yoke. Mark the actuator stem as a visual reference to verify that stem rotation does not occur. Remove the

stem connector before rechecking the bench set.

4. If movement occurs before or after the upper bench set pressure is reached, adjust the spring adjuster (see figure

4). Thread the adjuster up or down on the actuator stem until the actuator stem movement is first detected at the

upper bench set pressure. (Note: You may need to lower the loading pressure to reduce spring compression,

allowing the spring adjuster to turn.)

5. Be sure the spring adjuster is adjusted to meet the requirements of step 4 above.

6. Slowly decrease diaphragm loading pressure to the lower bench set pressure, as indicated on the nameplate. This

will extend the actuator stem toward the valve. Mark the end of the actuator stem on a nearby surface using tape or

some other method.

7. Slowly increase the diaphragm loading pressure until the upper bench set pressure is reached. Again, the travel stop

cap screw (key 12) should be against the upper diaphragm casing.

8. Measure the distance between the mark or tape to the end of the actuator stem. This distance should match the

rated travel indicated on the nameplate.

9. If the measured travel matches the nameplate travel, bench set is complete. Proceed to the Installing the Stem

Connector Assembly subsection.

10. If the measured travel is not exact, consider the spring free-length and spring rate tolerances may produce a

slightly different bench set than specified. Contact your Emerson Process Management sales office for assistance.

ForPushDowntoOpen(ReverseActing)Valves

1. If not already accomplished, push the valve stem down away from the actuator to the open position. Later, when

installingtheconnector,pullupthevalvestemtotheclosedposition.

2. Set the diaphragm loading pressure to a value less than the lower bench set pressure, as indicated on the

nameplate, or near zero. The down travel stops (key 77) should be contacting the yoke.

3. Slowly increase the pressure towards the lower bench set pressure while checking for the first linear movement of

the actuator stem.

Note

Before turning the spring adjuster on size 70, 76, or 87 actuators, assemble the stem connector around the actuator stem and the

anti-rotating lug on the yoke. Mark the actuator stem as a visual reference to verify that stem rotation does not occur. Remove the

stem connector before rechecking the bench set.

4. If movement occurs before or after the lower pressure is reached, adjust the spring adjuster (see figure 4). Thread

the adjuster up or down on the actuator stem until the actuator stem movement is first detected at the lower bench

set pressure.

5. Apply the upper bench set pressure indicated on the nameplate to the diaphragm. This will retract the actuator

stem away from the valve. Mark the end of the actuator stem on a nearby surface using tape or some other method.

6. Slowly decrease the diaphragm pressure until the lower bench set pressure is applied. Again, the down travel stops

(key 77) should be against the yoke.

7. Measure the distance between the mark or tape to the end of the actuator stem. This distance should match the

rated travel indicated on the nameplate.

8. If the measured travel matches the nameplate travel, bench set is complete. Proceed to the Installing the Stem

Connector Assembly subsection.

9. If the measured travel is not exact, consider the spring free-length and spring rate tolerances may produce a slightly

different bench set than specified. Contact your Emerson Process Management sales office for assistance.

Installing the Stem Connector Assembly

When installing the stem connector assembly (key 31), theactuatorandvalvestemthreadsshouldengagethe

threads of the stem connector by a distance equal to the diameter of the stem.

WARNING

Install the stem connector securely before a positioner is mounted to the actuator and pressurized, using only a

regulator-controlled air supply, not the positioner, to move the actuator stem.

To avoid personal injury or property damage, keep hands and tools out of the actuator stem travel path while applying

loading pressure to move the actuator stem in the following steps.

CAUTION

To avoid damaging the seating surfaces, do not rotate the valve plug while it is seated. Exercise care while installing the

stem connector assembly to avoid damage to the valve plug stem and valve stem threads.

Note

Replacement stem connectors are an assembly of two stem connector halves, cap screws, and a spacer between the connector

halves. Remove the spacer and discard it, if present, before clamping the actuator and valve stems together. Use only a mated pair

of stem connectors.

1. Ifnecessary,pushthevalvestemdownsothatthevalveplug is touching the seat ring on direct-acting valves. For

reverse-acting valves, pull the stem up to the closed position. Always start with the valve plug on the seat.

2. If necessary, screw the valve stem locknuts down, away from the connector location. For all actuators except size

87, ensure that the travel indicator disk (key 34) is on top of the locknuts.

3. Adjust the diaphragm pressure to the lower bench set pressure (or, the upper bench set pressure for reverse-acting

valves.) This should be the same pressure used in the Spring Verification steps, and it is marked on the nameplate.

4. Place the stem connector half with the threaded holes approximately half way between the actuator and valve

stems, and align the actuator stem and valve stem with threads from both stems mated root-to-crest with the stem

connector. If the threads from one of the stems do not fully align with the stem connector, a slight change to

Instruction Manual

D100310X012

667 Size 30-76 and 87 Actuators

November 2013

loading pressure may be necessary to align the threads. Refer to figures 6, 7, and 8 to help locate the connector

position.

CAUTION

Incomplete engagement of either the valve stem or actuator stem in the stem connector can result in stripped threads or

improper operation. Be sure that the length of each stem clamped in the stem connector is equal to or greater than one

diameter of that stem. Damage to threads on either stem or in the stem connector can cause the parts to be replaced

prematurely. Do not loosen the cap screws when the stem connector has spring or loading pressure force applied.

5. Install the other half of the stem connector and insert the cap screws and tighten them while ensuring even spacing

between the stem connector halves on all sides. If installing a positioner, also attach the feedback bracket at the

same time.

CAUTION

Over-tightening the valve stem locknuts can make disassembly difficult.

6. Screw the valve stem locknuts up against the stem connector for the size 87 actuator. For all other actuator sizes,

screw the valve stem locknuts up until the indicator disk contacts the bottom of the stem connector. Do not

overtighten the locknuts.

7. Slowly stroke the valve from fully open to fully closed and verify full rated travel is achieved.

Be sure that the valve is in the closed position. Loosen the screws on the travel indicator scale (key 32), and align it with

the travel indicator disk (key 34). Stroke the valve full travel to ensure that the travel matches the rated valve travel on

the nameplate. If valve travel is not correct, repeat the stem connector procedure.

Friction Discussion

If you are attempting to adjust the bench set after the actuator is connected to the valve and the packing tightened,

you must take friction into account. Make the spring adjustment so full actuator travel occurs at the bench set values

(a) plus the friction force divided by the effective diaphragm area with increasing diaphragm pressure or (b) minus the

friction force divided by the effective diaphragm area with decreasing diaphragm pressure.

If the stem connector assembly has been installed, the valve friction may be determined by the following procedure:

1. Install a pressure gauge in the actuator loading pressure line that connects to the actuator diaphragm casing.

Note

Steps 2 and 4 require that you read and record the pressure shown on the pressure gauge.

2. Increase the actuator diaphragm pressure and read the diaphragm pressure as the actuator reaches a travel

position in the rated travel of the valve that does not contact a travel stop. Make a reference mark on the travel

indicator scale using tape or some other method at this point.

3. Increase the actuator diaphragm pressure until the actuator is at a travel position greater than the position

referenced in step 2 using the reference point to identify first movement.

Instruction Manual

D100310X012

667 Size 30-76 and 87 Actuators

November 2013

4. Decrease the actuator diaphragm pressure and read the diaphragm pressure as the actuator returns to the position

referenced in step 2.

The difference between the two diaphragm pressure readings is the change in the diaphragm pressure required to

overcome the friction forces in the two directions of travel.

5. Calculate the actual friction force:

It is difficult to rotate the spring adjustor (key 74, figures 6, 7, and 8) when the full actuator loading pressure is applied

to the actuator. Release the actuator loading pressure before adjusting. Then re-apply loading pressure to check the

adjustment.

Deadband Measurement

Deadband is caused by packing friction, unbalanced forces, and other factors in the control valve assembly. Deadband

is the range a measured signal can vary without initiating a response from the actuator (see figure 5). Each actuator

spring has a fixed spring rate (force divided by compression). You have verified that the right spring was installed in the

actuator by completing the Spring Verification steps.

Deadband is one factor that affects the control valve assembly operation during automatic loop control. The control

loop tolerance for deadband varies widely depending on the loop response. Some common symptoms of the

deadband being too wide are no movement, a “jump” movement, or oscillating movements of the actuator during

automatic loop control. The following steps are provided to determine the span of deadband. The percent of

deadband is helpful in troubleshooting problems with the process control loop.

1. Start at a pressure near the lower bench set pressure, slowly increase pressure until the valve is approximately at

mid-travel. Note this pressure reading.

Deadband = Deadband, psi =nn%

Bench Set Span, psi

Loading Connection

Key number locations are shown in figures 6, 7, and 8, unless otherwise noted.

The loading pressure connections are made at the factory if the valve, actuator, and positioner come as a unit. Keep

the length of tubing or piping as short as possible to avoid transmission lag in the control signal. If a volume booster,

valve positioner, or other accessory is used, be sure that it is properly connected to the actuator. Refer to the

positioner instruction manual or other manuals as necessary. For actuators shipped separately or whenever the

actuator pressure connections are installed, use the following steps:

1. Connect the loading pressure piping to the NPT internal connection in the side of the yoke (key 73).

2. For size 70 and 87 actuators, if necessary, remove the 1/4 NPT bushing if a 1/2 NPT internal connection is needed to

increase connection size. The connection can be made with either piping or tubing.

3. Cycle the actuator several times to be sure that the valve stem travel is correct when the correct pressure ranges are

applied to the diaphragm.

4. Ifvalvestemtravelappearstobeincorrect,refertotheBench Set Spring Adjustment procedures at the beginning

of this section. Do not place the valve in service if it is not reacting correctly to diaphragm loading pressure changes.

Maintenance

Actuator parts are subject to normal wear and must be inspected regularly and replaced when necessary. The

frequency of inspection and replacement depends on the severity of service conditions.

WARNING

Avoid personal injury or property damage from sudden release of process pressure or uncontrolled movement of parts.

Before performing any maintenance operations:

DDo not remove the actuator from the valve while the valve is still pressurized.

DAlways wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal

injury.

DDisconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the

actuator cannot suddenly open or close the valve.

DUse bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure

from both sides of the valve. Drain the process media from both sides of the valve.

DVent the power actuator loading pressure and relieve any actuator spring pre-compression.

DUse lock-out procedures to be sure that the above measures stay in effect while you work on the equipment.

DThe valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the

pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings, or when

loosening the packing box pipe plug.

Top-Mounted Handwheel Assembly (Adjustable Down Travel Stop)

Actuator key numbers are shown in figures 6, 7, and 8. And, top-mounted handwheels are shown in figures 9, 11, 12,

and 13.

Note

If repeated or daily manual operation is expected, the actuator should be equipped with a side-mounted handwheel rather than a

casing-mounted travel stop or top-mounted handwheel. The side-mounted handwheel is designed for more frequent use as a

manual operator.

A top-mounted handwheel assembly (figures 9, 11, 12, and 13) is usually used as an adjustable down travel stop to

limit full extension of the actuator stem. Turning the handwheel counterclockwise pulls the extension rod (key 150,

figures 9, 11, and 12) up, retracting the actuator stem.

Instructions are given below for complete disassembly and assembly. Perform the disassembly only as far as necessary

to accomplish the required maintenance; then, begin the assembly at the appropriate step.

Note

For size 70 and 87 actuators with handjack bars (figure 13) it is recommended that the handjack bar (key 58) be removed when

not in use and the handwheel cap (key 247) be installed for weather protection of the internal components.

Side-Mounted Handwheel Assembly for Size 34 through 60 Actuators

A side-mounted handwheel assembly (figures 14 and 15) is usually used as a manual actuator. This design is frequently

used to drive the valve open or closed under loading conditions. Turning the handwheel clockwise past the neutral

position always closes a push-down-to-close valve. A pair of levers (key 146, figure 14) on a handwheel assembly close

the valve by moving the valve stem.

Instructions are given below for disassembly and assembly. Perform the disassembly only as far as necessary to

accomplish the required maintenance; then begin the assembly at the appropriate step.

Disassembly for Side-Mounted Handwheel (34-60)

1. If desired, the handwheel assembly can be removed from the actuator yoke. To do this, remove the nuts (keys 147

and 170) from the U-bolts and J-bolts (keys 166 and 143) thatholdtheassemblytotheyokeforthesize34and40

actuators. Remove the nuts (keys 170 and 144) from the U-bolts (keys 166 and 143) that hold the assembly to the

yoke for the size 45 through size 60 actuators.

2. Remove the retaining ring (key 154), and driveouttheleverpivotpin(key153).

3. Two screws (key 156) hold the right- and left-hand levers (key 146) together. Remove the screw from the top of the

levers so that the levers will drop down out of the assembly. Disassemble further, if necessary, by removing the

other screw.

4. Remove the screw (key 161) and pointer mounting bolt (key 159, not shown) located behind the pointer (key 160).

5. Remove the nut (key 54), lockwasher (key 150), and washer (key 149), and take off the handwheel (key 51). Be

careful not to lose the small ball (key 55) and spring (key 56).

6. Unscrew the bearing retainer (key 136) after loosening the locking set screw (key 168, not shown for the size 34

and 40 actuators).

7. Pull the screw assembly (key 145) out of the handwheel body. The operating nut (key 132) will come out with the

screw. Also, remove the bushing (key 151) on sizes 34 and 40.

8. If required, remove the bearings (key 152), one from the bearing retainer and the other from the handwheel body.

Assembly for Side-Mounted Handwheel (Sizes 34-60)

1. Pack the bearings (key 152) with anti-seize lubricant (key 244). Insert one bearing and the bushing (key 151) in the

handwheel body (key 142) as shown in figure 14 or 15. The bushing is not used in a handwheel assembly for size 45

through 60 actuators.

2. Coat the screw threads with anti-seize lubricant (key 244), and thread the operating nut onto the screw. Slide the

second bearing (key 152) onto the screw, and insert the end of the screw into either the bushing (key 151) as shown

in figure 14 or 15 or into the bearing.

3. Thread the bearing retainer (key 136) into the body (key 142). Completely tighten the bearing retainer, and then

loosen it one-quarter turn. Tighten the set screw (key 168, not shown for the size 34 and 40 actuators) to hold the

bearing retainer in place.

4. Coat the groove in the handwheel body (key 142) with lithium grease (key 241). Insert the spring (key 56) and ball

(key 55) into the handwheel (key 51). Holding the ball and spring in the handwheel, put the handwheel (key 51), the

washer (key 149), the lockwasher (key 150), and the hex nut (key 54) on the end of the screw (key 145). Tighten the

hex nut.

239),slidetheendofthelowersleevewiththegrooveinto the bearing retainer flange, turn the handwheel, and

feedthesleevethroughthewormgearsothattheslotinthe lower sleeve engages the key (key 122) in the yoke.

Continue turning the handwheel until the lower sleeve protrudes 81 mm (3.19 inches) below the surface of the

yoke. The bottom of the lower sleeve should be even with the bottom of the extension on the neutral indicator.

9. Pack the thrust bearing (key 128) with anti-seize lubricant (key 239). Slide the actuator stem (key 144) and the

attached adjusting screw (key 131), pin (key 130), thrust bearing (key 128), spring seat (key 19), and spring adjuster

(key 74) into the yoke. The lower end of the stem slides through the lower sleeve (key 123) and the lower sleeve

slides into the adjusting screw (key 131), as shown in figure 16.

10. Position the actuator stem (key 144) against the valve stem. Clamp both stems between the two halves of the

stem connector (key 31), and be sure the threads are engaged properly on both stems. The stem connector should

not be closer than 3.2 mm (1/8 inches) to the lower sleeve when the actuator stem is in the retracted position. This

adjustment will provide approximately 3.2 mm (1/8 inches) of free travel of the lower sleeve in either direction for

manual operation. Fasten the halves together with the cap screws.

11. Puttheactuatorspring(key18)intheyokeonthespringseat(key19).

adaptor (key 89), lower diaphragm casing (key 64), and O-ring (key 70) on the yoke.

15. Insert and tighten the cap screws (key 90).

16. Slide the lower diaphragm plate (key 71), the diaphragm (key 3) with the patterned side up, the diaphragm plate

(key 4), the spacer (key 2), and the cap screw (key 12) on the actuator stem (key 144). Tighten the cap screw.

17. Put the diaphragm casing (key 1) on the diaphragm. Align the holes in the diaphragm (key 3) and the diaphragm

casings (keys 1 and 64).

Note

When you replace actuator diaphragms in the field, take care to ensure the diaphragm casing bolts are tightened to the proper

load to prevent leakage, but not crush the material. Perform the following tightening sequence with a manual torque wrench for

size 30-76 and 87 actuators.

CAUTION

Over-tightening the diaphragm cap screws and nuts (keys 13 and 14) can damage the diaphragm. Do not exceed 27 NSm

(20 lbfSft) torque.

Note

Do not use lubricant on these bolts and nuts. Fasteners must be clean and dry.

18. Install the cap screws and hex nuts (keys 13 and 14) and tighten in the following manner.

19. Thefirstfourboltstightenedshouldbediametricallyopposedand90degreesapart.Tightenthesefourboltsto13

20. Tighten the remaining bolts in a clockwise, criss-cross pattern to 13 NSm(10lbfSft).

21. Repeat this procedure by tightening four bolts, diametrically opposed and 90 degrees apart, to a torque of 27 NSm

(20 lbfSft).

22. Tighten the remaining bolts in a clockwise, criss-cross pattern to 27 NSm(20lbfSft).

23. After the last bolt is tightened to 27 NSm(20lbfSft), all of the bolts should be tightened again to 27 NSm(20lbfSft)

in a circular pattern around the bolt circle.

24. Once completed, no more tightening is recommended.

25. Return the actuator to service after completing the Loading Connection procedure in the Installation section and

theproceduresintheAdjustmentssection.

Casing-Mounted Travel Stops

Note

If repeated or daily manual operation is expected, the actuator should be equipped with a side-mounted handwheel rather than a

casing-mounted travel stop or top-mounted handwheel. The side-mounted handwheel is designed for more frequent use as

manual operator.

Casing-mounted adjustable travel stops (shown in figures 17 through 21) are available to limit travel in the down

direction (extending the actuator stem) or in the up direction (retracting the actuator stem). The travel stop in figure

17 is a down travel stop, the travel stop in figure 18 is an up and down travel stop, and the travel stops in figures 19, 20,

and 21 are up travel stops.

Use the locknuts (key 151, figures 17 and 18), stem (key 150, figure 19), handwheel (key 58, figure 20) or cap screw

(key 177, figure 21) to set the point at which the travel stop limits travel. Be sure to tighten the locknuts and replace

the cap (key 149, figures 17 and 19; key 247, figure 18) after setting the travel stop.

Instructions are given below for disassembly and assembly. Perform the disassembly only as far as necessary to

accomplish the required maintenance; then, begin the assembly at the appropriate step.

Key numbers are shown in figures 17 through 21.

1. Remove the cap (key 149 or 247) if the travel stop uses one. For down travel stops, loosen the locknuts (key 151,

figures 17 and 18) so that the stop is not causing any spring compression.

Instruction Manual

D100310X012

667 Size 30-76 and 87 Actuators

November 2013

2. Bypass the control valve, reduce loading pressure to atmospheric, and remove the tubing or piping from the

connection on top of the yoke (key 73, figures 6, 7, and 8).

3. For down travel stops, turn the spring adjuster (key 74, figures 6, 7, and 8) out of the yoke toward the stem

connector (key 31) to relieve all the compression in the spring (key 18).

4. For style 11 travel stops (figure 18), unscrew the cap screws (key 161), and make sure that the guide plate (key 157)

can turn between the handwheel body (key 148) and the mounting plate (key 158).

5. Useawrenchonthenuts(key151)tounscrewtheextension rod (key 150). Remove the rod, the handwheel body

(key 148), and the attached parts.

6. Unscrew the hex nuts and cap screws (keys 14 and 13, figures 6, 7, and 8) from the diaphragm casings. Lift off the

upper diaphragm casing (key 1, figures 6, 7, and 8) and, for the style 11 travel stop, the mounting plate (key 158).

For styles 10, 12 and 13, the travel stop assembly will be removed with the casing.

7. Note and record the position of travel stops (key 152) relative to the cap screws (key 154) for use in assembly.

Unscrew the travel stops and cap screws, and remove either the mounting plate (key 158) or the handwheel body

(key 148) and attached parts.

8. Separate the stem (key 150) and screw (key 160, figure 18) from the handwheel body.

9. Before reassembling, lubricate parts indicated by key 239 in figures 17 through 21. Use anti-seize lubricant (key

239).

10. Reassemble parts in the reverse order of removal.

11. When replacing the cap screws (key 154) and, if used, the travel stops (key 152), be sure to return them to their

original position as recorded in step 7.

CAUTION

Over-tightening the diaphragm cap screws and nuts (keys 13 and 14), figures 6, 7, and 8 can damage the diaphragm. Do

not exceed 27 NSm (20 lbfSft) torque.

12. Install the cap screws and nuts (keys 13 and 14, figures 6, 7, and 8) and finger tighten. Tighten the diaphragm cap

screws and nuts to 27 NSm(20lbfSft) torque in a crisscross pattern.

13. Return the spring adjuster (key 74, figure 6, 7, and 8) to its original position. Re-adjust the travel stop.
