Check Valves（Input Side, Port Type P：Threaded）

Check valves are available in various shapes such as straight type and elbow type, and can be selected from different body materials, sealing materials, input/output ports, etc. At MISUMI, you can purchase these together with other parts used for pneumatic equipment.

[What is a check valve?]
A check valve is a pneumatic part used to prevent back flow of air. It is also used to ensure negative pressure by setting the air flow in one direction. The mechanism differs among products. There are those with a lid that tightens using the force of the spring when the air flows backward, and those with a lid that closes by the pressure difference when the air flows backward.
