Check valves will prevent flow in one direction and facilitate flow in the opposite direction. Check valves are sometimes called non-return valves. Spring-Loaded Ball Check Valves are equipped with swivel fittings along with 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 Spring-Loaded Ball Check Valves have configurable fittings, O-rings, and cracking pressures.
