CVR0 VALVE SERIES
GAS Insert - 350 bar
Direct acting - Poppet type
DESCRIPTION
A screw-in, direct acting, poppet type in-line check valve. Main use is as a blocking or load-holding device. The CVR0 allows flow
passage from port 2 to 1: the cartridge has a fully guided check which is spring-biased closed until sufficient pressure is applied at
port 2 to open to 1. The flow is blocked in the opposite direction (1 to 2).
