WARNING
Always wear protective gloves,
clothing and eyewear when performing
any installation operations to avoid
personal injury.
Personal injury or property damage
caused by sudden release of pressure
or bursting of pressure retaining parts
may result if service conditions exceed
those for which the product was
intended. To avoid injury or damage,
provide a relief valve for over pressure
protection 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
This valve is intended for a specific
range of pressures, temperatures and
other application specifications.
Applying different pressures and
temperatures to the valve could result
in parts damage, malfunction of the
control valve or loss of control of the
process. Do not expose this product to
service conditions or variables other
than those for which the product was
intended. If you are not sure what

June 2010

these conditions are you should
contact your Emerson Process
Management sales office for more
complete specifications. Provide the
product serial numbers (shown on the
nameplate) and all other pertinent
information.

WARNING
If you move or work on an actuator
installed on a valve with loading
pressure applied, keep your hands and
tools away from the stem travel path to
avoid personal injury. Be especially
careful when removing the stem
connector to release all loading on the
actuator stem whether it be from air
pressure on the diaphragm or
compression in the actuator springs.
Likewise take similar care when
adjusting or removing any optional
travel stop. Refer to the relevant
actuator Maintenance Instructions.
If hoisting the valve, take care to
prevent people from being injured in
case the hoist or rigging slips. Be sure
to use adequate sized hoists and
chains or slings to handle the valve.

WARNING
Personal injury could result from
packing leakage. Valve packing is
tightened before shipment; however,
the packing might require some
readjustment to meet specific service
conditions.

that must be taken to protect against
process media.

Maintenance
WARNING
Avoid personal injury and property
damage from sudden release of
process pressure or bursting of parts.
Before performing any maintenance
operations:
D Do not remove the actuator from
the valve while the valve is still
pressurized.
D Always wear protective gloves,
clothing, and eyewear when
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 Depending on the actuator
construction, it will be necessary to
manage the pneumatic actuator spring
precompression. It is essential to
refer to the relevant actuator
instructions in this manual to perform
safe removal of the actuator from the
valve.
D Use lock-out procedures to be
sure the above measures stay in effect
while you work on the equipment.
D The 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.
D Check with your process or safety
engineer for any additional measures

Note
Whenever a gasket seal is disturbed
by removing or shifting gasketed
parts, install a new gasket during
reassembly. This provides a good
gasket seal because the used gasket
may not seal properly.

Flow Direction
The preferred flow direction for selfdraining is
shown in figures 8 and 9.

Installation
1. Before installing the valve in the pipeline,
thoroughly clean the line of all dirt, welding chips,
scale, oil or grease, and other foreign material. A
micron size filter is recommended upstream of the
valve.
2. Install valve so that the controlled fluid will flow
through the valve body in the direction selected in
figures 8 and 9. The leak detection port should be
located at the lowest point in the installed position.
3. A threevalve bypass must be used to permit
removal of the control valve from the line without
shutting down the system.
4. To detect if leakage or breakage of the
diaphragm has occurred, a pressure gauge may be
installed in the 1/8 NPT port (key 14) in the bonnet,
see figures 4, 5, and 6.

WARNING
To avoid personal injury or property
damage, do not attempt to do any work
on a valve while the system is in
operation, the valve must be isolated
100% from the active system and the
isolated line voided of pressure and/or
hazardous fluids.

Air Piping

Actuator Removal

1. For an airtoextend actuator (airtoclose
action), connect the actuating air pressure line to the
1/4 NPT opening in the upper diaphragm case. For
an airtoretract actuator (airtoopen action)
connect the actuating air pressure line to the 1/4
NPT in the lower diaphragm case.

To remove the actuator, unscrew the drive nut
(key 9) and loosen the jam nuts (key 27). Unscrew
the piston stem (key 3) from the actuator stem.

2. Use 6.4 mm (1/4 inch) O.D. tubing or equivalent
for all air lines. If the air line exceeds 8 m (25 ft) in
length, 9.5 mm (3/8 inch) tubing is preferred. Air
lines must not leak. Air pressure should not exceed
2.5 bar (35 psig).

Valve Body Removal

CAUTION
Avoid personal injury or property
damage from sudden release of
pressure or bursting of parts. Remove
the actuator before attempting to
disassemble the valve.

Bonnet Disassembly

Reference figures 4, 5, and 6.
(Not Required For Actuator Reversal)

Actuator Removed

For field replacement of the diaphragm (key 8),
follow steps 1 through 4 below.

Remove the diaphragm (key 8) and the bonnet
Oring (key 15) (NPS 11/2 and 2 valves only) per
instructions under the previous Valve Body Removal
section. Proceed as follows:

Note
Do not squeeze the valve body in a
vise.
1. For failclosed action (airtoopen), stroke the
actuator up to take pressure off from the diaphragm
pushing against seat. For failopen action
(airtoclose), there is no need to stroke actuator.
2. Remove the bonnet screws (key 18) for NPS 1
valves or the clamp (key 11) for NPS 11/2 or 2
valves.
3. Lift the bonnet assembly (key 2) with the actuator
from the valve body (key 1).
4. Once disassembled; for failclosed action ONLY,
release pressure from the actuator to be able to
unscrew the diaphragm, for failopen action you
must pressurize the actuator to unscrew the
diaphragm. This is the only action required for
inspection or cleaning.

1. Turn over the bonnet assembly (key 2).
2. Pry out the retaining ring (key 7) using a small flat
screwdriver.
3. Remove the wave springs (key 6), compressor
(key 5) and drive mechanism (key 4).
4. Push out the pistonstem assembly (key 3).
Clean and replace as required.
Note
For NPS 11/2 & 2 valves, measure the
gap between the free ends of the
clamp (key 11) and return to this
position upon reassembly to minimize
change in zero calibration.

Bonnet Reassembly
Actuator Removed

5. Stroke the actuator down to exert some pressure
and remove the diaphragm (key 8) by unscrewing
the diaphragm (key 8) from the compressor (key 5).
Remove the bonnet Oring (key 15) (NPS 11/2 and
2 valves only). Wipe the diaphragm (key 8) with a
clean soft cloth and examine for wear.

For correct orientation of the subassemblies to the
bonnet refer to figure 7, exploded view.

6. Inspect the valve body sealing surfaces. If valve
leakage becomes excessive, replacement of the
diaphragm (key 8) may be necessary.

3. Verify that the machined surfaces at the end of
the rectangular plates are in full contact with the
machined recess inside the bonnet (key 2).

1. Insert the piston stem assembly (key 3) into the
bonnet (key 2).
2. Orient the drive mechanism as shown in figure 7.

Instruction Manual

84000 Valve

June 2010

4. IMPORTANT: Verify that the recessed roller
bearings in the drive mechanism (key 4) rest against
the flats of the piston stem assembly (key 3).
5. Install the compressor (key 5) per figures 4, 5,
and 6 with the flat side resting against the extended
roller bearings.
6. Drop the wave springs (key 6) into place, prongs
down; the NPS 1 valve requires two wave springs.
The NPS 11/2 and 2 valves require three wave
springs. Oppose the spring opening 180 degrees
when installing the wave springs.
7. Retain all parts by installing the retaining ring
(key 7) into the bonnet groove.
8. The gap in the retaining ring (key 7) should align
with the crest of the wave spring (key 6).
9. Push down on the bonnet assembly to drive the
piston stem assembly (key 3) firmly into the drive
mechanism (key 4) to provide some tension.
10. Insert the Oring (key 15) (NPS 11/2 and 2
valves only), so that it rests on the retaining ring
(key 7).
11. Lubricate the screw thread and the cone of the
diaphragm (key 8) with sterile food grade lubricant.
12. Screw the diaphragm (key 8) onto the
compressor (key 5) snugly. DO NOT
OVERTIGHTEN.
13. Place the complete bonnet assembly onto the
valve body (key 1).
a. The diaphragm (key 8) rim must fit into the
body groove for proper centering.
b. The NPS 1 bolted flange configuration should
be tightened for metaltometal contact between
the flange and the valve body. Be sure to use 45
lbfSft when tightening the valve body bolts on the
NPS 1 valve.
c. For NPS 11/2 and 2 valves, apply the clamp
(key 11) and tighten the nut gradually, checking
for an even amount of PTFE over the valve body,
between the bonnet and clamp, for proper
centering.

Valve Calibration
After the valve is assembled per the previous
instructions, install the properly configured actuator
(reference the Baumann Pneumatic Actuators
instruction manual, D103352X012), making sure to
engage the piston stem (key 3) as much as possible
into the actuator stem. Tighten the drive nut (key 9).
(Refer to figures 8 and 9 for the preferred flow
direction.)

Calibration of FailClose (AirtoOpen)
Actuator
1. Apply 50 psi air or nitrogen to port B. Apply 3 psi
air signal to the actuator.
a. Slowly turn the piston stem assembly (key 3)
out of the actuator stem until flow stops.
Note
When adjusting the valve stem, do not
grip the stem directly with pliers or a
wrench. This will damage the surface
of the stem. Instead, countertighten
the two locknuts on the stem together.
This will allow you to turn the stem by
turning the locknuts with a wrench.
b. Check the valve for leaks with 50 psi air under
the diaphragm (port B). Leakage should be less
than 1 cc/min. The valve should start to leak or
low flow at a minimum pressure signal to the
actuator. If it takes more than minimum pressure
to open, then screw the piston stem assembly
(key 3) further into the actuator stem. If the valve
is not tight at 3 psi signal, screw the piston stem
assembly (key 3) out of the actuator stem further.
Next, calibrate Zero on the travel indicator scale
with a minimum pressure signal to the actuator.
Check for full travel at the maximum pressure
signal. If the leak persists, increase the force on
the clamp (key 11) to compress the diaphragm
(key 8) by tightening the clamp nut. For NPS 1
valves, tighten the bolts (key 18) on the bonnet
flange (key 11) using 45 lbfSft.

CAUTION
d. The gap between the clamp ends should be
approximately 1/2 inch or less for proper
diaphragm compression. DO NOT
OVERTIGHTEN THE CLAMP.
e. Examine through port B to ensure the
diaphragm is centered on the seating area.

The stem should travel below zero by
approximately 1/16 to 1/8 inch after the
signal is decreased below 3 psi. IF THE
VALVE DOES NOT CLOSE PROPERLY,
INCREASE THE CLAMP
COMPRESSION AROUND THE

Instruction Manual

84000 Valve
DIAPHRAGM (key 8) by tightening 1/2
turn. DO NOT tighten to the point that
the diaphragm wrinkles.

Calibration of FailOpen (AirtoClose)
Actuator
2. Apply 50 psi air pressure or nitrogen to port B.
Apply 15 psi air signal to actuator.
a. Slowly turn the piston stem assembly (key 3)
out of the actuator stem until flow stops.
b. Check the valve for leaks with 50 psi air under
the diaphragm (port B). Leakage should be less
than 1 cc/min. The valve should start to leak or
low flow at a maximum pressure signal to the
actuator. If it takes more than the maximum
pressure to open, then screw the pistonstem
(key 3) further into the actuator stem. If the valve
is not tight at 15 psi signal, screw the pistonstem
(key 3) out of the actuator stem further. Next,
calibrate Zero on the travel indicator scale with
maximum pressure signal to the actuator. Check
for full travel at minimum pressure signal. If the
leak persists, increase the force on the clamp
(key 11) to compress the diaphragm (key 8) by
tightening the clamp nut. For NPS 1 valves,
tighten the bolts (key 18) on the bonnet flange
(key 11) using 45 lbfSft.

CAUTION
The stem should travel below zero by
approximately 1/16 to 1/8 inch after the
signal is increased above 15 psi. IF
THE VALVE DOES NOT CLOSE
PROPERLY, INCREASE THE CLAMP
COMPRESSION AROUND THE
DIAPHRAGM (key 8) by tightening 1/2
turn. DO NOT tighten to the point that
the diaphragm wrinkles.

June 2010

Note
When using a Baumann 32 actuator
with dual stops or a Baumann 54
