Special Purpose Pneumatic Fittings

Check Valves and Stop Valves

Check valves allow air flow in one direction and block air flow in the reverse direction.

Pilot-operated check valves work as a normal check valve until pressure is applied to the pilot port, allowing reverse flow.

Stop valves block upstream air pressure when the downstream pneumatic tube is removed from the fitting.

• Inch and metric valve fitting sizes available
• Select models have release rings that are color coded to differentiate between inch (black) and metric (blue) sizes)
• Check valves available in thermoplastic push-to-connect or nickel-plated brass threaded models
• Push-to-connect models are for use with polyurethane tubing or nylon tubing

Shuttle Valves

Shuttle valves automatically select the higher of two inlet pressures and direct that flow to the outlet.

• Various porting options, including push-to-connect fittings and threaded connections
• Nickel-plated brass or anodized aluminum body models
• Nickel-plated brass threads
• Low cracking pressure (less than 1 psi)

Accessories for Special Purpose Pneumatic Fittings
