“0R” Series – 1/8" thru 3/4" Ports

General Information

Quick exhaust valves provide rapid exhaust of control air

when placed between control valve and actuator. They can

also be used as shuttle valves. Diaphragm materials are

available in urethane, Nitrile, Fluorocarbon, and PTFE to

meet a wide variety of operating conditions.

Valve Specification

Operating Pressure (Air)

Maximum:

150 PSIG



00 PSIG for Model No. 0R37TB (PTFE diaphragm)

Minimum:

3 PSIG

50 PSIG for Model No. 0R37TB (PTFE diaphragm)

Operating Temperature:

Urethane: 0°F to 180°F* (-18°C to 80°C)

Nitrile: 0°F to 180°F* (-18°C to 80°C)

Fluorocarbon: 0°F to 00°F* (-18°C to 05°C)

PTFE: 0°F to 500°F* (-18°C to 60°C)

* Ambient temperatures below freezing require moisture-free air.

Ambient temperatures below freezing and above 180° require

lubricants especially selected for suitability at these temperatures.

Pneumatic valves should be used with filtered and lub icated air.
