Quick Exhaust & Shuttle Valves
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 Specifications
Operating Pressure (Air)
Maximum:
150 PSIG
200 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 400°F* (-18°C to 205°C)
PTFE: 0°F to 500°F* (-18°C to 260°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 lubricated air.
