and Threaded Pneumatic Fittings
Union Straight Check Valves
Check flow valves allow air flow in one direction and block air flow in the reverse direction. NITRA air pneumatic push-to-connect Check Valve fittings have tough thermoplastic bodies and stainless steel tube gripping claws.
|NITRA Union Check Valves - threaded nickel-plated brass ... New!
All valve bodies are nickel-plated brass. These high quality check valves work well in pneumatic circuits requiring free flow in one direction and no flow in the opposite direction.
|NITRA Pilot Operated Check Valves ... New!
These valves are designed for use in applications requiring an actuator to be locked in position. They work as a normal check valve (free flow from inlet to outlet, no flow outlet to inlet) until pressure is applied to the pilot port to allow free flow from outlet to inlet.
Union Straight Stop Valves
NITRA pneumatic push-to-connect Air Stop Valve fittings have tough thermoplastic bodies and stainless steel tube gripping claws. When the downstream pneumatic tube is removed from the stop valve, upstream air pressure is blocked.
