Service

Caution: Disconnect or shut off air supply and exhaust

the primary and secondary pressures before servicing

unit. Turning the T-handle counterclockwise does not

vent downstream pressure on non-relieving regulators.

Downstream pressure must be vented before servicing

regulator.

Caution: Grease packets are supplied with kits for

lubrication of seals. Use only mineral based grease or

oils. Do not use synthetic oils such as esters. Do not

use silicones.

Note: After servicing unit, turn on air supply and adjust regulator

to the desired downstream pressure. Check unit for leaks. If

leakage occurs, do not operate - conduct repairs and retest.

A. Servicing the Bonnet and Diaphragm Assembly

1. Turn the T-handle counterclockwise until the compression is

released from the Pressure Control Spring.

2. Remove Bonnet Mounting Screws, Bonnet Assembly,

Pressure Control Spring and Spring Button. Remove

Diaphragm Assembly. Next, disassemble, clean, and carefully

inspect parts for wear and / or damage. Wipe parts, clean

with soapy water or denatured alcohol. If using compressed

air to blow dry, be sure to wear appropriate eye protection. If

replacement is necessary, use parts from service kits.

3. Install Diaphragm Assembly, Pressure Control Spring, Spring

Button as shown below. Then, install Bonnet Assembly to

Body with Mounting Screws and tighten in an alternating or

star pattern to the following torque specifications:

1/4", 3/8", 1/2" ..................... 2.3 to 4.5 Nm (20 to 40 in. lb.)

3/4", 1-1/4", 1-1/2" ............... 6.8 to 7.9 Nm (60 to 70 in. lb.)

Lightly grease with provided lubricant.

Inspect for nicks, scratches, and surface imperfections. If present,

reduced service life is probable and future replacement should

be planned.

Clean with lint-free cloth.

B. Servicing the Poppet Assembly

1. Exhaust system media pressure as previously described.

Then remove Bottom Plug by unscrewing it from Body.

Next, remove Bottom Plug, O-ring, Bottom Spring and Inner

Valve Assembly.

2. Next, disassemble, clean, and carefully inspect parts for

wear and / or damage. If replacement is necessary, use

parts from service kits.

3. Lubricate O-ring and sliding surfaces using grease supplied

with service kit.

4. Install parts as shown.

5. Lubricate Bottom Plug O-ring and install it in o-ring groove

on Bottom Plug. Be sure Inner Valve Stem fits into center

area of Diaphragm Assembly before installing Bottom Plug.

Then screw Bottom Plug into Body until it bottoms out in

body. Tighten to 3.5 to 5.1 Nm (35 to 45 in. lb.).

6. Turn on media source and adjust to desired secondary

pressure as described in the Operation section. Check

regulator for leakage. If leakage occurs, DO NOT OPERATE

— conduct repairs again.

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

your local authorized dealer or your customer service

representative.
