DIAPHRAGM DESIGN AIR OPERATED VALVE
OPERATION & MAINTENANCE MANUAL
1.0 INSTALLATION
All valves are factory adjusted and tested at the pressure marked on the operator label.
Refer to Parker Autoclave Engineers’ Valves, Fittings and Tubing Catalog (installation
section) for proper tubing connection installation.
The air supply connection on the operator is 1/8” NPT. The recommended value for air
pressure at the maximum valve operating pressures is shown on the operator label. The
maximum allowable working pressure of the operator is 100 psi for OL, CL, OM and
CM operators and 70 psi for OH and CH operators.
 Anextendingstufngboxmust be used at temperatures below-100°F. or above 800°F.
Refer to Autoclave Engineers’ Valves, Fittings and Tubing Catalog (Specialty Valves Section)
for pressure ratings at various temperatures.
Use minimum required air pressure (CL, CM and CH operators) or minimum required
spring precompression (OL, OM and OH operators) to increase stem and seat life. Refer to
the Air Operator Sizing Data in the Valve Actuators Section of the VFT Catalog.
Applications which require extended cycle life should be considered on an individual basis.
!! CAUTION !!
! For proper operation of air operated valves, the pressure
inlet to the valve should always be below the seat.
!! Rotating the operator with the valve in the closed
position will damage the seat voiding the warranty.

SPRING ADJUSTMENT - OL, OM and OH VALVES ONLY
On some sizes of the OL, OM and OH operators, the spring limits the travel at the maximum
pressures.Thisaffectstheowcapacityofthevalve.SeetheAirOperatorSizingDatainthe
ValveActuatorsSectionoftheVFTCatalogforactualsystemtravelandowcoefcient.
If a longer stem travel is desired when the operating pressure is less than the maximum, then this
should be requested at the time of order so that the valve will be properly adjusted at the factory. If
a valve has already been set for a higher operating pressure and a longer stem travel is desired, the
valvemayhavetobereturnedtothefactoryforstemandpackingreplacementandrenishingof
the seat to assure an effective valve seat seal in the closed position.
3.0 PACKING ADJUSTMENT
When the valve packing starts to leak, follow the steps below to reseal the valve stem.
1. Relieve all pressure in the valve body.
2. CL, CM and CH Valves Only:
Relieve all air pressure to the operator inlet.
OL, OM and OH Valves Only:
Apply and maintain air pressure to the operator inlet (so the stem is unseated).
3. Loosen the packing gland locking device.
4. While holding the valve body secure, use a torque wrench to tighten the packing gland
to the value shown on the attached installation summary chart. If a torque wrench is
not available, tighten the packing gland approximately 1/16 turn.
5. Pressurize the valve and check for leaks.
6. If the packing still leaks, relieve all pressure in the valve and repeat steps 4 and 5.
If the packing does not seal after several attempts, it probably needs replacement
(refer to section 4.0).
NOTE: Do not attempt to tighten packing gland by grasping
and turning the diaphragm operator housing.
7. Install the packing gland locking device.
8. OL, OM and OH Valves Only:
Relieve air pressure to the operator.

4.0 PACKING OR STEM REPLACEMENT
To change packing or stem, follow the steps listed below.
1. Relieve all pressure from the valve and operator.
2. OL, OM and OH Valves Only:
Loosen the jam nut on top of the spring housing, then loosen the screw until all spring
compression is relieved. Apply air (approximately 20 psi) and maintain pressure to the
operator (so the stem is unseated).
3. Loosen the packing gland locking device.
4. While holding the valve body secure, loosen the packing gland.
5. Completely loosen the packing gland and remove the valve body. The packing will stay
on the stems that have a larger stem tip below the packing.
6. If the stem does not have a larger stem tip and only the packing is being replaced, go to
Step #7.
For stems that do have a larger stem tip or if the stem is being replaced, the operator must be
disassembled so that the stem may be removed. Follow the instructions for disassembly of the
operator in section 5.0 and remove the stem from the diaphragm head. Remove the packing
gland and o-ring retainer (OL, OM and OH only) from the stem.
7. Remove the packing from the stem (stems with larger stem tip) or from the valve body
(stems without this tip).
8. Place new packing and washers on the stem or in the valve body.
9. For stems with a larger stem tip, slide the stem through the packing gland and place the
o-ring retainer (OL, OM and OH only) over the stem as shown in Figure 1. Follow the
operator reassembly instructions in Section 5.0.
10 Place the packing gland locking device over the gland and install the gland into the valve
body. OL, OM and OH only: apply and maintain air pressure to the operator
(approximately 20 psi). While holding the valve body secure, tighten the packing gland to the
value shown on the attached installation summary chart.
11. Secure the packing gland locking device.
12. OL, OM and OH Valves Only: Relieve air pressure to the operator and tighten the
screw on top of the spring housing until the stem bottoms out on the seat. Back the
screw off, then hand tighten. Tighten the screw the distance shown on the installation
summary table. An equivalent amount of screw revolutions is also given. Once
completed, tighten the jam nut securely in place.

5.0 SEAT REPLACEMENT (Replacement Seat Valves)
When the seat requires replacement, use the following procedure.
1. Relieve all pressure from the valve.
2. (OL, OM, and OH valves only)
Loosen the jam nut on top of the spring housing then loosen the screw until all spring
compression is relieved. Apply and maintain air (approximately 20 psi) to the operator
to move the stem to the "open" position.
(CL, CM and CH valves only)
Relieve all pressure to the air operator.
3. While holding the valve body secure, remove the seat retainer or the seat.
4. Inspect the seat for signs of wear or damage. Replaceable seats may be reversed if
only one side is worn. If both sides are worn, use a new seat.
5. Place the seat in the body and install the seat retainer. While holding the body secure,
torque the seat retainer to the valve in the installation summary chart.
6. OL, OM, and OH valves only.
Relieve all air pressure to the operator. Adjust the spring pre-compression per the
