Check Valves
[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.
