Specifications
Specifications are shown in table 1 and the
specifications for a given valve are stamped on a
nameplate attached to the valve.

Note
When installing a valve after it has
been in long-term storage, cycle the
valve at least ten times to re-energize
the dynamic seal.
Please contact your Emerson Process Management
sales office if you have any questions about
preparing a valve for storage or if you are planning
to put into service a valve that has been stored for
some time.

Adjusting the Travel Stops
CAUTION
When using manual or power
actuators, adjust the actuator travel
stops so the disc stop in the valve
body does not absorb the output of
the actuator.
For actuators without travel stops, the
actuator must be properly mounted to
prevent it from driving the valve disc
against the valve disc travel stop.
Failure to limit actuator travel as
described in this section can result in
damage to the valve shafts or other
valve parts.
Note

Installation
WARNING
Always wear protective gloves,
clothing, and eyewear when
performing any installation operations
to avoid personal injury.
Check with your process or safety
engineer for any additional measures
that must be taken to protect against
process media.
If installing into an existing
application, also refer to the WARNING
at the beginning of the Maintenance
section in this instruction manual.

An ”S” is visible on both the valve
shaft and valve body. When the valve
disc is closed, the ”S” on the shaft
aligns with the ”S” on the valve body.
1. Locate the actuator travel stop that establishes
the closed position of the valve disc. When adjusting
the travel stop make sure that the disc is from 0 to
0.76 mm (0 to 0.030 inch ) away from the internal
stop in the valve body. This adjustment is necessary
to be certain that the actuator output torque is fully
absorbed by the actuator travel stop rather than the
stop in the valve body.
For actuators without travel stops, the actuator must
be properly mounted to prevent it from driving the
valve disc against the valve disc travel stop.

Instruction Manual
Form 5338
February 2007

A11 Valve
1. To mount an actuator without travel stops, first, if
necessary, remove the actuator from the valve.
Then, position the valve disc from 0 to 0.76 mm (0 to
0.030 inch) away from the internal stop in the valve
body.
2. Now, travel the actuator to the maximum position.
Keep the actuator in the maximum travel position.
Return the actuator to the valve, taking care not to
disturb the position of the valve disc.
3. Mount the actuator on the valve using proper
bolts with locking washers to achieve a secure fit.
4. Before installing the valve/actuator assembly in
the process line, cycle the valve several times to be
sure the valve disc returns to the proper position.

Preparing for Installation
WARNING
If the Type A11 valve is equipped with
a fail-open actuator, remove the
actuator before installing the
valve/actuator assembly or cycle the
valve into the fully closed position.
Then, to avoid possible personal injury
or property damage, take appropriate
steps to ensure that the actuator does
not cause the valve to open during
installation.
1. If the valve and actuator have been purchased
separately or if the actuator has been removed for
storage, travel stop adjustment, or maintenance,
mount the actuator before inserting the
valve/actuator assembly into the line. Refer to the
actuator instruction manual for mounting and
adjustment procedures.

CAUTION
To avoid product damage, inspect the
valve before installation for any
damage or any foreign material that
may have collected in the valve body.
Also remove any pipe scale, welding
slag, or other foreign material from the
pipeline.
2. Remove the protective end covers from the valve
and inspect the valve body to be certain that it is free
of foreign material. Also, be certain that adjacent
pipelines are free of any foreign material, such as

pipe scale or welding slag that could damage the
valve seating surfaces.

WARNING
The Type A11 valve is designed for
use with the appropriate piping
schedule for the ASME class.
However, before putting the valve into
operation, measure carefully to ensure
disc rotation without interference from
piping or flanges. Be certain to center
the valve accurately to prevent
interference of the disc with the
flanges.
D The edges of a rotating disc have
a shearing effect that may result in
personal injury. To help prevent such
injuries, stay clear of the disc edges
when rotating the disc.
D Damage to the disc will occur if
any pipe flanges or piping connected
to the valve interfere with the disc
rotation path. If the piping flange has a
smaller inner diameter than specified
for schedule 80 piping, measure
carefully to be certain the disc rotates
without interference before putting the
valve into operation.
3. Select the appropriate gaskets for the application.
flexible graphite, spiral wound, or other gasket types,
made to ASME B16.5 group or user’s standard, can
be used on Type A11 valves depending on the
service conditions of the application. Note: spiral
wound gaskets, when properly centered, will cover
more than 60 percent of the gasket area at the
retaining ring screws.
For metal-seated and cryogenic valve gasket
recommendations, please contact your Emerson
Process Management sales office.
4. Refer to the appropriate table for the quantity and
size of flange bolts required (table 4 or 5) and
proceed with the following instructions.

Valve Orientation
Type A11 valve bodies are designed for installation
with the shaft in any orientation around the pipeline:
horizontal, vertical, or at an angle. However, when
installing a Type A11 valve, please follow these
recommendations.

D In certain services (process fluids with high
concentrations of entrained solids, abrasive slurries,
or polymerizing media), valve performance will be
enhanced by installing the valve with the shaft
horizontal to the pipeline.
D Valves supplied for unidirectional shutoff should
be installed with the high pressure at the back
(waterway side) of the disc. A flow tag with an arrow
is provided for proper installation.
The High Performance Butterfly Valve is designed to
allow flow in either direction when in the open
position. When in the closed position, high pressure
should be applied to a specific side of the disc to
provide best performance and optimal service life.
D Valves supplied for bidirectional shutoff, such
as soft or Phoenix III, under normal operating
conditions can (at different times) experience
pressure in both directions; the highest of the two
pressures should be exerted on the preferred side of
the disc. If the two pressures are equal, then the one
lasting the longest period of time should be applied
to the preferred side. A flow tag with an arrow is
provided for proper installation.
If you have questions about proper valve orientation
in a specific application, contact your Emerson
Process Management sales office.

Installing the Valve
WARNING
Always wear protective gloves,
clothing, and eyewear when
performing any installation operations
to avoid personal injury.
To avoid personal injury or property
damage resulting from the sudden
release of pressure, do not install the
valve assembly where service
conditions could exceed the limits
given in this manual, the limits on the
appropriate nameplates, or the

matching pipe flange rating. Use
pressure-relieving devices as required
by government or accepted industry
codes and good engineering practices.
Check with your process or safety
engineer for any additional measures
that must be taken to protect against
process media.
If installing into an existing
application, also refer to the WARNING
at the beginning of the Maintenance
section in this instruction manual.

CAUTION
When ordered, the valve configuration
and construction materials were
selected to meet particular pressure,
temperature, pressure drop, and
controlled fluid conditions.
Responsibility for the safety of
process media and compatibility of
valve materials with process media
rests solely with the purchaser and
end-user. Since some valve/body trim
material combinations are limited in
their pressure drop and temperature
ranges, do not apply any other
conditions to the valve without first
contacting your Emerson Process
Management sales office.
For Wafer Style Valves:
1. See figure 3. Install the lower flange bolts first to
form a cradle for the valve.
2. Properly orient the valve according to the specific
application. Be sure the valve is placed in the line so
the flow properly enters the valve. Then, install the
valve and the gaskets between the flanges into the
cradle formed by the flange bolts.
3. Install the remaining flange bolts, making sure
that the gaskets are centered on the gasket sealing
surfaces of the flange and valve body.
4. Tighten the flange bolts in an alternating
criss-cross fashion to a torque value of one-fourth of

Instruction Manual
Form 5338

B2263/IL

Figure 3. Proper Installation Procedure

the final bolting torque. Repeat this procedure
several times increasing the torque value each time
by a fourth of the final desired torque. When the final
torque value has been applied, tighten each flange
bolt again to allow for gasket compression.
For Single Flange Valves:
1. Position the valve between the flanges. Be sure
to leave enough room for the flange gaskets; then
install the lower flange bolts.
2. Install the gaskets and align the valve and the
gaskets.
3. Install the remaining bolts.
4. Tighten the flange bolts in an alternating
criss-cross fashion to a torque value of one-fourth of
the final bolting torque. Repeat this procedure
several times increasing the torque value each time
by a fourth of the final desired torque. When the final
torque value has been applied, tighten each flange
bolt again to allow for gasket compression.

Thrust Washers
Two thrust washers are used in valve sizes 10-inch
and larger (Class 150), 8-inch and larger (Class
300), 8-inch and larger (Class 600). The thrust
washers are located at the upper and lower bearing
areas of the valve. Thrust washers must be installed
before the disc is installed in the valve body.

Packing Adjustment and Shaft Bonding
WARNING
Personal injury could result from
packing leakage. Valve packing was
tightened before shipment; however,
the packing might require some
readjustment to meet specific service
conditions. Check with your process
or safety engineer for any additional
measures that must be taken to
protect against process media.
1. For PTFE or graphite packing: Tighten
standard packing follower nuts only enough to

Instruction Manual
Form 5338

prevent shaft leakage. Excessive tightening of
packing will accelerate wear and could produce
higher rotating friction loads on the valve shaft. If
necessary, refer to the Packing Maintenance
section.

2. For ENVIRO-SEAL Packing Systems: These
packing systems will not require this initial
re-adjustment. Refer to the separate ENVIRO-SEAL
Packing System for Rotary Valves Instruction
Manual, Form 5305 for repair and adjustment
procedures.
3. For hazardous atmosphere or oxygen service
valves, read the following Warning, and provide the
bonding strap assembly mentioned below if the
valve is used in an explosive atmosphere.

WARNING

VIEW A-A

Figure 4. Optional Shaft-to-Body Bonding Strap
Assembly

5. Connect the other end of the bonding strap
assembly to the valve flange cap screws.
The valve drive shaft is not necessarily
grounded to the pipeline when
installed. Personal injury or property
damage could result, if the process
fluid or the atmosphere around the
valve is flammable, from an explosion
caused by a discharge of static
electricity from the valve components.
If the valve is installed in a hazardous
area, electrically bond the drive shaft
to the valve body.

Note
The packing is composed of all
conductive packing rings (graphite
ribbon packing) or partially conductive
packing rings (carbon-filled PTFE
female adaptor with PTFE V-ring
packing or graphite-composition
packing ring with PTFE/composition
packing) to electrically bond the shaft
to the valve for hazardous area
service. For oxygen service
applications, and hazardous area
service where the standard packing
doesn’t provide sufficient
shaft-to-valve body bonding, provide
alternate shaft-to-valve body bonding
according to the following step.
4. Attach the bonding strap assembly (key 131,
figure 4) to the shaft with the clamp (key 130,
figure 4).

6. For more information, refer to the Packing
Maintenance section below.

Maintenance
Valve parts are subject to normal wear and must be
inspected and replaced as necessary. The
frequency of inspection and replacement depends
upon the severity of service conditions.

WARNING
Avoid personal injury from sudden
release of process pressure. Before
performing any maintenance
operations:
D Disconnect 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.
D Use bypass valves or completely
shut off the process to isolate the
valve from process pressure. Relieve
process pressure on both sides of the
valve. Drain the process media from
both sides of the valve.
D Vent the power actuator loading
pressure.

D Use lockout procedures to be
sure the above measures stay in effect
while you work on the equipment.
D Always wear protective gloves,
clothing and eyewear when performing
any maintenance operations to avoid
personal injury.
D The valve packing area 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.
D Check with your process or safety
engineer for any additional measures
that must be taken to protect against
process media.

necessary, stroke the actuator to place
the disc in the closed position while
removing the valve from the pipeline.
7. Before removing the valve from the pipeline,
make sure the valve disc is closed. See figure 3.
Rotate the shaft clockwise until the disc makes
contact with the internal stop or actuator travel stop
(if still installed). The ”S” stamped on the shaft
should be aligned with the ”S” on the valve body.
8. After removing the valve from the pipeline, move
it to an appropriate work area. Remove the actuator
from the valve.

Packing Maintenance
The Type A11 valve is designed so the shaft packing
can be replaced without removing the valve from the
process pipeline. Refer to figure 8 for available
packing configurations and figure 9 for part key
numbers.

CAUTION
When using an actuator, the actuator
travel stop (or actuator, for actuators
without adjustable stops) must be
adjusted so the disc stop in the valve
does not absorb the output of the
actuator. Failure to limit the actuator
travel can result in damage to the
valve, shaft(s), or other valve
components.

Removing the Valve
For field repair, remove the valve from the pipeline.

WARNING
Using the procedures listed in the
above WARNING, loosen the flange
bolting that holds the valve. Make sure
the valve cannot slip or twist while the
bolting is being loosened and
removed.

CAUTION
Damage to the disc can occur if the
disc is not closed when the valve is
being removed from the pipeline. If

CAUTION
The packing flange should be
tightened only enough to prevent shaft
leakage. Excessive tightening will only
accelerate wear of the packing and
could produce higher torques on the
valve.
In most cases, packing leakage can be eliminated by
merely tightening the hex nuts located above the
packing flange while the valve is in the pipeline.
However, if leakage continues, the packing must be
replaced.
1. Before loosening any parts on the valve, be sure
the pipeline has been depressurized. Then, remove
packing nuts (key 16), lift off the packing flange

1. After the valve has been removed from the line
and the manual or power actuator has been
removed, manually rotate the shaft (key 4)
counter-clockwise until the disc has moved a
full 180_. Note that the ”S” on the shaft is 180_ from
the ”S” on the valve body.
2. Lay the valve flat on a work bench in a secure
position with the retaining ring (key 2) and retaining
ring screws (key 22) facing up. Use blocks or other
appropriate techniques to support the valve.
Remove all retaining ring screws.
3. Remove the retaining ring by placing a retaining
ring screw in each of the two retaining ring jack
screw holes. With the appropriate tool, slowly rotate
the screws until the retaining ring has been lifted

CAUTION

In the following step, use the
appropriate tool to avoid damage to
the seal or T-slot area of the valve.
4. Different valve types have different seal designs
and components. To see the appropriate seal, refer
to figure 5. Insert the appropriate tool under the top
edge of seal and gently pry the seal out. Take care
not to damage the seal or T-slot area of the valve
body. After the seal has been removed, clean the
T-slot area, retaining ring and, if required, polish the
disc thoroughly with fine steel wool or other
appropriate material.

4. When the seal is thoroughly seated, re-install the
retaining ring and screws. Tighten the retaining
screws just enough to eliminate vertical movement
of the retaining ring. With the use of the blunt end
tool, carefully tuck the lip of the seal ring under the
retaining ring.
5. When the seal is under the lip of the retaining
ring, tighten the screws according to standard
procedures. Manually rotate the valve shaft
clockwise 180_ to return the disc to its closed
position against the internal stop.
6. The final seating of the retaining ring screws can
now be done. For the screw torque values, refer to
table 6. The seal is now fully installed and the valve
may be closed for installation or storage.

Soft Seal Installation
1. Locate the replacement seal ring (key 8) and note
the shape of the ring. The ring is wider across one
edge diameter and narrower across the other edge
diameter as shown in figure 6. Around the outside
circumference is one wide groove.
Before installing the seal ring into the valve body, the
backup ring (key 9) must first be placed onto the
wide, outer groove of the seal ring.
2. The seal ring and backup ring assembly must be
installed in the valve. The wider outside diameter of
the seal ring goes into the T-slot area of the valve
body, shown in figure 7. Start the wider diameter
edge of the seal ring into the T-slot of the valve body
using a blunt end screwdriver.
3. Carefully tuck the backup ring downward into the
valve body T-slot until the seal ring and back-up ring
are completely entrapped in the valve body T-slot.

Metal and Phoenix III Seal Installation
For metal seal installation:
Locate the replacement seal ring (key 8) and note
the shape of the ring. The ring is wider across one
edge diameter and narrower across the other edge
diameter as shown in figure 6. Around the outside
circumference is one wide groove.
Install the seal ring (key 8) into the valve body by
first placing the wider outside diameter of the seal
ring into the T-slot area of the valve body which is
shown in figure 7. Metal seals without a back-up ring
will fall into place. Metal seals with a back-up ring
(key 9) will have to be installed following the
instructions given below for the Phoenix III seal with
back-up ring.

circumference is one wide groove.
Install the seal ring in the valve body by first placing
the wider outside diameter of the seal ring, as
marked in figure 6, into the T-slot area of the valve
body which is shown in figure 7. Phoenix III seal
rings without a back-up ring will fall into place. If the
Phoenix III seal uses a back-up ring (key 9), the
back-up ring will have to be installed after placing
the seal ring in the valve using a blunt end
screwdriver. Do not use the screwdriver or seal tool
directly on the metal seat. Use a tool only on the
backup ring.
2. With the seal ring inserted all the way around the
valve body T-slot now lay the backup ring into the

This gasket is a thin graphite material.
Take care to avoid damaging the

4. Install the retaining ring and align the screw holes
in the retaining ring with the holes in the valve body.
Install the first retaining ring screw through the
punched hole in the ring gasket. Install the other ring
screws by pushing the screws through the graphite
gasket and threading them into valve body.
5. Tighten the retaining ring screws just enough to
eliminate vertical movement of the retaining ring. Do
not tighten the retaining ring screws.

WARNING
Avoid personal injury or property
damage caused by the impact of a
falling or tipping large valve. Large
valves must be properly supported
during maintenance.
6. To complete this step, stand the valve up.

CAUTION

If a vise or other clamps are being
used, be sure damage is not done to
the flange gasket sealing area of the
valve body.
7. Manually rotate the valve shaft to turn the disc
clockwise to meet the seal.
8. Tap the disc with a rubber mallet to drive it
against the internal travel stop. When the disc
makes contact with the stop, manually rotate the
disc counter-clockwise back out of the seal to a 90_
open position. Repeat steps 7 and 8 three times.
9. The final seating of the retaining ring screws can
be done. For the screw torque values, refer to
table 6. The seal is now fully installed and the valve
may be closed for installation or storage.

Cryogenic Seal Installation
1. Locate the replacement seal ring (key 8) and note
the shape of the ring. The ring is wider across one
edge diameter and narrower across the other edge
diameter as shown in figure 6. Around the outside
circumference is one wide groove.
For Kel-F seals with aluminum backup rings
only: Now, locate the replacement V-ring. Please
notice that the V-ring is similar in diameters to the
seal ring. Place the V-ring down onto the seal ring
with the larger diameter of the V-ring going first. Be
sure the larger diameters on both rings are down.
2. For all types: Install the seal ring (or seal ring
and V-ring) in the valve body by first placing the
wider outside diameter of the seal ring into the T-slot
area of the valve body. The seal ring with or without
a back-up ring will fall into place.
3. Once the seal ring (or seal ring and V-ring) have
been fully installed into the valve body T-slot, the
retaining ring gasket can be installed.

4. Install the retaining ring and align the screw holes
in the retaining ring with the holes in the valve body.
Install the first retaining ring screw through the
punched hole in the ring gasket. Install the other ring
screws by pushing the screws through the graphite
gasket and threading them into the screw holes in
the valve body.
5. Tighten the retaining ring screws just enough to
eliminate vertical movement of the retaining ring. Do
not tighten the retaining ring screws.

CAUTION
If a vise or other clamps are being
used, be sure damage is not done to
the flange gasket sealing area of the
valve body.
7. Manually rotate the valve shaft to turn the disc
clockwise to meet the seal.
8. Tap the disc with a rubber mallet to drive it
against the internal travel stop. When the disc
makes contact with the stop, manually rotate the
disc counter-clockwise back out of the seal to a 90_
open position. Repeat steps 7 and 8 three times.
9. The final seating of the retaining ring screws can
be done. For the screw torque values, refer to
table 6. The seal is now fully installed and the valve
may be closed for installation or storage.

Valve Shaft/Disc Pin Unit Maintenance
CAUTION
This gasket is a thin graphite material.
Take care to avoid damaging the
gasket. However, punch one initial
screw hole through the gasket for
alignment purposes.

Valve Shaft/Disc Pin Unit Removal
1. Rotate the disc (key 3) 180_ counterclockwise
from the full closed position.
2. Place the open valve horizontally on a suitable
work surface with the retaining ring (key 2) facing
upward. Be sure to properly support the valve with
blocks while the shaft is being removed.

Figure 8. Packing Configurations

Note
The disc must be removed from the
waterway side of the valve body, which
is the side opposite the T-slot area.
Support the valve and disc so the disc
can be easily removed from the valve
when the shaft is removed.
3. Use a pin extractor to remove the disc pins
(key 6). Select the proper pin extractor tip with
screws of proper thread size to match the thread
size in the disc pins.
4. Screw the pin extractor tip into the pin as far as
possible. With an upward, straight sliding motion,
extract the pin. Repeat the same procedure for the
other pins.
A threaded rod with an appropriate spacer and nut
can also be used as an extractor tool. If using a
threaded rod, choose a rod with threads that fit the
inside threads of the pins. The rod should extend

several inches above the disc when screwed into a
pin.
5. After screwing the rod into the pin, slide the
spacer over the rod and pin. Thread the nut onto the
rod and tighten. As the nut is tightened, it will drive
the spacer against the disc and the increasing
pressure will draw the pin from the disc.
6. Loosen the packing nuts (key 16).
7. Extract the shaft (key 4) by hand-pulling or by
using the pin extractor screwed into the end of the
shaft.
Note
Valves with a two-piece shaft use a
gasket retainer, which must be
removed before removing the lower
shaft.

CAUTION
In the following step, remove the disc
from the waterway side of the valve to
avoid damage to the disc or T-slot area
of the valve.
8. Remember: the disc must be removed from the
waterway side of the valve. Do not try to force the
disc through the seal side of the valve. This could
cause severe damage to the disc and T-slot area.
After removing the shaft, remove the disc.
Valve Shaft/Disc Pin Unit Installation
Note
Replacement disc and shaft(s) are
provided as a matched set. When
replacing either the disc or shaft(s), a
matched set is required.
To replace the disc pin assembly (key 6), reverse
the removal steps used above.

Before placing disc into a valve body, properly align
the top of the disc with the top of the valve. A ”T” is
stamped on the disc to indicate alignment. Be sure
holes in the shaft are exactly aligned with the holes
in the disc before re-installing pins. After pins are
fully seated in the disc, use a punch or small chisel
to stake the pins at three points. This will prevent the
pins from working free and out of the disc due to
vibration.

Gasket Retainer
When two-piece shafts are used, a gasket retainer
assembly must be used. The gasket is held in place
by a gasket retainer and four hex head bolts and
lockwashers. When re-assembling the valve, this
gasket should always be replaced. Be sure the
gasket is centered over the shaft bore before
retightening bolts. Tighten down bolts evenly in a
cross over pattern or in a star pattern. Refer to table
6 for proper torque values.

Bearing Maintenance
Bearing Removal
To get access to the bearings (key 10), the disc and
shaft assembly (keys 3, 4 and 5) must be removed
from the valve. The bearings (key 10) may be
removed by using a brass drift punch and lightly
tapping them out. In valves without lower bonnets,
the lower bearing is removed by grasping it and
pulling upwards. Also, cryogenic valves have an
outboard bearing under the packing. Refer to the
Packing Maintenance section for instructions.
Bearing Installation
Before installation of the bearings, bearing bores
should be solvent cleaned and bearings will slip in.
