NITRA 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. Models are available with push-to-connect and/or threaded fittings.
