METRIC Cartridge - 300 bar
Direct acting - Poppet type
CVP0.M28 Valve Series
A screw-in, cartridge style, direct acting,
poppet type check valve. Main use is
as a blocking or load-holding device.
The CVP0.M28 allows flow passage
from port 2 to 1: the cartridge has a ful-
ly guided check which is spring-biased
closed until sufcient pressure is ap-
plied 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 hardened
and ground to guarantee minimal wear
and to extend service life. Compact size.
