WARNING
EXCEPT as otherwise specified by the manufacturer, this product is specifically designed for com-
pressed air service, and use with any other fluid (liquid or gas) is a misapplication. For example, use
with or injection of certain hazardous liquids or gases in the system (such as alcohol or liquid petroleum
gas) could be harmful to the unit or result in a combustible condition or hazardous external leakage.
Manufacturer's warranties are void in the event of misapplication, and manufacturer assumes no
responsibility for any resulting loss. Before using with fluids other than air, or for nonindustrial applica-
tions,or for life support systems consult manufacturer for written approval.
MAINTENANCE
1. The relief valve can be disassembled for servicing without removal from line.
2. TO DISASSEMBLE-shut off air to relief valve and vent air line on both sides
of relief valve. Turn adjusting screw counterclockwise to relieve compression
on spring. Remove knob, bonnet adjusting screw, regulating spring and slip
ring. Diaphragm assembly, seat plug and o-ring can now be removed.
3. Occasionally disassemble and clean body and valve seat.
4. IF UNIT WILL NOT RELIEVE AT REQUIRED PRESSURE-disassemble,
clean and check for wear or damage. Replace worn or damaged parts.

INSTALLATION
1. Install as close as possible to where the pressure relieving function is need-
ed.
2. Install the unit with the air flowing through the body in the direction indicated
on the body.
3. System piping should be same pipe size as relief valve porting. Avoid using
fittings, couplings, etc., that restrict the flow of air.
4. Gauge ports (
1

8
") are provided in either side of the relief valve body for
installation of a gauge or use as an additional outlet port. Plug unused
port(s).
5. Panel mount relief valves require a 1

" (31,32 mm) diameter hole and are
mountable on panels up to
1
/
8
" (3 mm) thick.
OPERATION
1. Maximum inlet pressure and operating temperature ratings are 125 PSIG
(8,5 bar) and 175°F (79°C).
2. Before turning on the supply air pressure, turn the adjusting knob counter-
clockwise until there is no load on the regulating spring. Turn on the supply
air pressure and then turn the adjusting knob clockwise until the desired
relief pressure setting is reached. When making a change in pressure set-
ting, always approach the desired pressure from a lower one. When reduc-
ing from a higher to a lower setting, first reduce to some pressure less than
that desired and then increase to the desired pressure.
