Technical Features
SAE/GAS Cartridge - 350 bar
Direct acting - Poppet type
CVD0 Valve Series
A screw-in, direct acting, poppet type
in-line check valve. Main use is as a
blocking or load-holding device. The
CVD0 allows flow passage from port
1 to 2: the cartridge has a fully guided
check which is spring-biased closed
until sufcient pressure is applied at
port 1 to open to 2. The flow is blocked
in the opposite direction (2 to 1).
All valve parts are made of high strength steel.
Poppet and seat are hardened and ground to
guarantee low wear and to extend service life.
Suitable for heavy duty applications.
Extremely compact size. SAE and Gas cavity.
