Direct acting - Poppet type
CVZ0.S08 Valve Series
A screw-in, cartridge style, direct
acting, poppet type check valve. Main
use is as a blocking or load-holding
device. The CVZ0.S08 allows flow
passage from port 2 to 1: the cartri-
dge has a fully guided check which
is spring-biased closed until suf-
cient pressure is applied at port
2 to open to 1. The flow is blocked
in the opposite direction (1 to 2).
All external surfaces are zinc plated and
corrosion-proof. All valve parts are made
of high strength steel. Poppet is harde-
ned and ground to guarantee minimal wear
and to extend service life. Compact size.
Optional bias springs for back-pressure ap-
plication flexibility. Industry common cavity.
