Special Purpose Pneumatic Fittings

Check Valves and Stop Valves

Newest Additions!

• CITO check 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.

• NITRA and CITO brands
• 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, brass threaded, or nickel-plated brass threaded models
• Push-to-connect models are for use with polyurethane tubing or nylon tubing

Shuttle Valves

NITRA 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 threads
• Low cracking pressure (less than 1 psi)

Bleed Valves

NITRA Bleed valves offer an easy solution to release trapped or excess air pressure from a pneumatic system. Simply press the button to exhaust air pressure.
