CV-1

The Welker CV-1 Check Valve is a ball-type valve designed to allow product flow in one direction only.

The ball in the standard CV-1 is spring-loaded to remain shut and will only operate once the upstream or inlet pressure exceeds the tension on the spring; this is referred to as the “cracking pressure.” The CV-1 can be ordered without a spring for vertical installation; without a spring, gravity causes the CV-1 to remain shut until upstream or inlet pressure exceeds the downstream or outlet pressure. Shutoff of the liquid or gas is achieved in both styles when the upstream or inlet pressure falls below the downstream or outlet pressure and the ball seats on an O-ring, forming a positive seal.
