Installation
1. The regulator should be installed with reasonable accessibility for
service whenever possible - repair service kits are available. Keep pipe
and 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
unit, possibly causing malfunction.
2. Install regulator so that media flow is in the direction of arrow (on
R342’s, R344’s & RA4’s), and into port labelled “IN”. Installation must
be upstream (high pressure) side and as close to the devices it is to
service (valve, cylinder, tool, etc.). Mounting may be in any position.
3. Gauge ports are located on both sides of the regulator body for your
convenience. It is necessary to install a gauge or pipe plugs into each
port during installation.
4. For protection against rust, pipe scale, and other foreign matter, install
a filter on the upstream (high pressure) side as close to the regulator
as possible.
Operation
1. Before turning on the media source, disengage the Adjusting Knob
by pulling upward. Turn the Adjusting Knob counterclockwise until
compression is released from the Control Spring. Then turn on media
source and adjust regulator to desired secondary pressure by turning
Adjusting Knob clockwise. This permits pressure to build up slowly,
preventing any unexpected operation of the valve, cylinders, tools, etc.,
attached to the line. Adjustment to desired secondary pressure can be
made only with primary pressure applied to the regulator.
2. To decrease regulator pressure setting, always reset from a pressure
lower than the final setting desired. For example, lowering the secondary
pressure from 550 to 410 kPa (80 to 60 PSIG) is best accomplished by
dropping the secondary pressure to 350 kPa (50 PSIG), then adjusting
upward to 410 kPa (60 PSIG).
Push the Adjusting Knob down to lock the pressure setting.

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.
Service
!
CAUTION:     
SHUT OFF MEDIA SOURCE and exhaust the primary and
secondary pressure before disassembling regulator unit. (Turning
the Knob counterclockwise reduces regulator’s setting, but does
not vent downstream pressure on non-relieving regulators.)

CAUTION:    
Lubricate parts with a mineral based oil / grease or silicone
grease. DO NOT use synthetic oils / greases such as esters.
A. ServicingtheBonnetandDiaphragmassembly-

to Body and tighten to 11.3 to 13.6 Nm (100 to 120 in. lb.).
B. ServicingthePoppetAssembly-
1. Exhaust system media pressure as previously described. Then remove
Bonnet by unscrewing it from Body. Next, remove Valve Seat, Poppet
Return Spring and Poppet 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
