Normally Closed Check Valves with Swivel Fittings

Check valves will prevent flow in one direction and facilitate flow in the opposite direction. Check valves are sometimes called non-return valves. Normally Closed check valves with swivel fittings have a ball and spring combination that will open once the pressure differential is greater than the spring force. The pressure differential that a normally closed check valve opens is called the "Cracking Pressure".

Air Logic's normally check valves with swivel fittings have configurable fittings, O-rings, and cracking pressures.
