METRIC Cartridge - 420 bar
Direct acting - Poppet type
CVC0.M22 Valve Series
A screw-in, cartridge style, direct acting,
poppet type check valve. Main use is
as a blocking or load-holding device.
The CVC0.M22 allows flow passage
from port 1 to 2: the cartridge has a ful-
ly guided check which is spring-biased
closed until sufcient pressure is ap-
plied 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 harde-
ned and ground to guarantee minimal wear
and to extend service life. Compact size.
Optional bias springs for back-pressu-
re application flexibility. Metric cavity.
