Construction Details
The Series CV40 and CV50 use Schedule 40 PVC construction with EPDM sealing components for compatible fluid-handling systems.
A stainless steel spring provides spring-loaded check operation. The valve begins opening at approximately 2 psi, allowing forward flow while helping prevent reverse flow when system pressure changes.
The CV40 configuration uses female threaded ends, while the CV50 configuration provides slip/socket ends for solvent-weld PVC piping installations.
