GAS Insert - 350 bar
Direct acting - Ball type
Description
A screw-in, direct acting, ball type in-line check valve. Main use is as a blocking or load-holding device. The CVB0.G18 allows flow passage from port 1 to 2: the cartridge has a fully guided check which is spring-biased closed until sufficient pressure is applied at port 1 to open to 2. The flow is blocked in the opposite direction (2 to 1). Reserved installation is possible (except for size G18) yet not recommended.
Technical Features
External surfaces are oxide burnished and corrosion-protected. All valve parts are made of high strength steel. Compact size. GAS cavity.
