Umbrella check valves are Air Logic's first-in-class robust innovation in low cracking force inline non-return valves. The plastic bodies with preloaded elastomer umbrellas are designed for cracking pressures below 2 psi. In the forward direction, the pressure pushes up on the umbrella and it is automatically opened to facilitate flow through the circuit. In the reverse flow direction, the pressure forces the umbrella against the seat of the product and prevents flow from occurring.

Air Logic's umbrella check valve is suitable for a wide range of OEM devices and applications. Industries include Medical Devices, Analytical Devices, Life Science, Consumer Products, Small Engines, and more.

Miniature check valves will prevent flow in one direction and facilitate flow in the opposite direction. Check valves are sometimes called non-return valves. Floating disk style check valves have a disk that will change position inside of the body with the flow of media. In the forward direction, the media is able to flow around the disk. In the reverse direction, the disk is pushed against the seat and prevents flow. 

Check valves will prevent flow in one direction and facilitate flow in the opposite direction. Check valves are sometimes called non-return valves. Floating disk-style check valves have a disk that will change position inside of the body with the flow of media. In the forward direction, the media is able to flow around the disk. In the reverse direction, the disk is pushed against the seat and prevents flow. These check valves combine the benefits of a soft silicone seat with a hard floating disk: great sealing characteristics and high reverse pressure ratings.

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 style check valves have a spring and disk 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 closed check valves combine the benefits of a soft silicone seat with a hard floating disk: great sealing characteristics and high reverse pressure ratings. 

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.
