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.

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
precompression. 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

that must be taken to protect against
process media.

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 selfdraining 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 threevalve 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

1. For an airtoextend actuator (airtoclose
action), connect the actuating air pressure line to the
1/4 NPT opening in the upper diaphragm case. For
an airtoretract actuator (airtoopen action)
connect the actuating air pressure line to the 1/4
NPT in the lower diaphragm case.

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

Reference figures 4, 5, and 6.

(Not Required For Actuator Reversal)

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

June 2010

Actuator Removal

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.

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

Actuator Removed

Remove the diaphragm (key 8) and the bonnet
Oring (key 15) (NPS 11/2 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 failclosed action (airtoopen), stroke the
actuator up to take pressure off from the diaphragm
pushing against seat. For failopen action
(airtoclose), 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 11/2 or 2
valves.

3. Lift the bonnet assembly (key 2) with the actuator
from the valve body (key 1).

4. Once disassembled; for failclosed action ONLY,
release pressure from the actuator to be able to
unscrew the diaphragm, for failopen action you
must pressurize the actuator to unscrew the
diaphragm. This is the only action required for
inspection or cleaning.

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 Oring (key 15) (NPS 11/2 and
2 valves only). Wipe the diaphragm (key 8) with a
clean soft cloth and examine for wear.

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

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 pistonstem assembly (key 3).
Clean and replace as required.

Note

For NPS 11/2 & 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

For correct orientation of the subassemblies to the
bonnet refer to figure 7, exploded view.

1. Insert the piston stem assembly (key 3) into the
bonnet (key 2).

2. Orient the drive mechanism as shown in figure 7.

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).
