Technical Features
SAE08 Cartridge - 420 bar
Direct acting - Poppet type
CVC5.S08 Valve Series
A screw-in, cartridge style, direct
acting, poppet type check valve.
Main use is as a blocking or load-hol-
ding device. The CVC5.S08 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 external surfaces are zinc plated and
corrosion-proof. All valve parts are made
of high strength steel. Poppet is hardened
and ground to guarantee minimal wear and
to extend service life. Compact size. Optio-
nal bias springs for back-pressure appli-
cation flexibility. Industry common cavity.
