Service Procedures

To dis-assemble unit, use the following procedure:

Using a Philips screwdriver, remove the four pan head screws to

dis-assemble the solenoid cover assembly from the solenoid conduit

plate. To detach the plate from the valve body assembly, remove

the 4 flat head screws (using a Philips screwdriver).To remove the

stem, stem guide, and seals from the body, unscrew the end plug

using a 3/8" Allen wrench. Remove plunger return spring and flat

washer. Then gently press on the “pin” side of the stem until it

slides out of the body. The stem guide may be removed by pulling

axially on the radial holes drilled in it. Be careful not to scratch the

sealing surfaces or cut the seals.

Thoroughly clean the valve body bore and stem guide, and inspect

for possible nicks, scratches and material imperfections. Lightly

lubricate the stem seals. (Use a non-detergent hydro-carbon based

oil or grease.) Replace any o-rings or other seals if they are

damaged.

The Assembly procedure is the reverse of the above. (It is best to

set the solenoid in its up-right position on the conduit plate and

then place solenoid cover over the solenoid.) Be sure to position

separator as shown. Apply 8-12 in-lbs of torque to the flat head

screws. Tighten the end plug to 60 in-lbs and apply 15-18 in-lbs of

torque to the pan head mounting screws.

If you have questions concerning how to service this unit, contact

your local authorized dealer or your customer service

representative.

Application Limits

These products are intended for use in general purpose

compressed air systems only.

Operating Pressure Range:

psig Bar kPa

Minimum 0 0 0

Maximum 150 10 1000

OperatingTemperature Range:

0°F to 160°F (-18°C to 71°C)

Voltage Range:

Installation & Operating Instructions

Valve should be installed with reasonable accessibility for service

whenever possible - repair service kits are available. Keep pipe or

tubing lengths to a minimum with inside clean and free of dirt and

chips. Pipe joint compound should be used sparingly and applied

only to the male pipe - never into the female port. Do not use

PTFE tape to seal pipe joints - pieces have a tendency to break

off and lodge inside the unit, possibly causing malfunction.

Filtered and lubricated air is necessary for maximum valve life and

minimum maintenance.

Factory Pre-Lubrication - All valves are pre-lubricated at

assembly with a petroleum based grease.

Wiring Instructions -The green wire shall be connected to ground;

there is no polarity requirement for the two power leads.

Note: Follow all requirements for local and national electrical

codes.

Valve Operation:

These valves will operate mounted in any position; they are also

suitable for vacuum service.

Connect inlet to port “A” for normally closed valve. Port “B” is

exhaust.

WARNING

To avoid unpredictable system behavior that can cause personal injury

and property damage:

• Disconnect electrical supply (when necessary) before installation,

servicing, or conversion.

• Disconnect air supply and depressurize all air lines connected to

this product before installation, servicing, or conversion.

• Operate within the manufacturer’s specified pressure, temperature,

and other conditions listed in these instructions.

• Medium must be moisture-free if ambient temperature is below

freezing.

• Service according to procedures listed in these instructions.

• Installation, service, and conversion of these products must be

performed by knowledgeable personnel who understand how

pneumatic products are to be applied.

• After installation, servicing, or conversion, air and electrical

supplies (when necessary) should be connected and the product

tested for proper function and leakage. If audible leakage is present,

or the product does not operate properly, do not put into use.

Maintenance &Trouble Shooting Hints:

Noisy Solenoid:

1. Check voltage and hertz ratings of main electrical source.

This must agree with the solenoid rating.

2. Inspect solenoid plunger bar and mating frame laminations

for damaged contact surfaces, and dirt particle

contamination.

3. Check solenoid holddown spring for distortion, deterioration,

and excessive wear.

4. Check stem for peened and/or flared condition.

5. Check solenoid plate, and solenoid cover mounting screws

for looseness.

Air LeakageThrough Exhaust Ports:

1. Check for internal leakage in cylinder being operated by

valve.

2. Check center stem seal for nicks, cracks, peeling and/or

delamination.

3. Check for missing, damaged, swollen, or incorrectly

assembled o-rings and gaskets.

4. Check stem guide and body bore for nicks, scratches, and

dirt particles.

Replace worn or damaged parts. Re-assemble and re-test unit.

and applied only to the male pipe - never into the female port.

Do not use PTFE tape to seal pipe joints - pieces have a

tendency to break off and lodge inside the unit, possibly causing

malfunction.

Valves will operate when mounted in any position. They are

also suitable for vacuum service. A pilot pressure of 207 kPa

(30 psig) or more is recommended to operate these valves.

Pilot pressure does not need to be increased as line pressure

is increased.

Series C & CW (wall mounting) valves can be operated either

normally closed to pressure or normally open to pressure.

Connect inlet to port “A” for normally closed valve. Port “B” is

exhaust. Connect inlet to port “B” for normally open valve. Port

“A” is exhaust. Plug exhaust port for 2-Way operation.

Factory Pre-Lubrication - All valves are pre-lubricated at

assembly with a petroleum based grease. Filtered and lubricated

air is necessary for maximum valve life and minimum

maintenance.

Service Procedure

Caution: Shut off air supply and exhaust pressure trapped

within the unit before servicing.

Servicing Valve & Actuator Assemblies:

To remove the

pressure actuator assembly

(item 11) from the

valve body, unscrew the mounting screws (item 15). Remove

the piston and lip seal from the piston cap (item 14).To remove

the spool, spool guide, and seals from the valve body, unscrew

the end plug using a 3/8" Allen wrench. Then gently press on

the “pin”side of the spool until it slides out of the valve body.

Service Procedures

To disassemble unit, use the following procedure:

Philips screwdriver). To remove the stem, stem guide, and

seals from the body, unscrew the stem guide retainer using a

1 1/16" hex wrench. Then gently press on the “pin” side of the

stem until it slides out of the body. The stem guide may be

removed by pulling axially on the radial holes drilled in the

stem guide. Be careful not to scratch the sealing surfaces or

cut the seals.

Thoroughly clean the valve body bore and stem guide, and

inspect for possible nicks, scratches and material imperfections.

Lightly lubricate the stem seals. (Use a non-detergent hydro-

carbon based oil or grease.) Replace any o-rings or other

seals if they are damaged.

The Assembly procedure is the reverse of the above. Tighten

the stem guide retainer at 60-180 in-lbs (6.7 to 20.3 Nm) and

apply 15-18 in-lbs (1.7 to 2.0 Nm) of torque to the pan head
