METRIC Cartridge - 420 bar
Direct acting - Poppet type
ICV0.M20 Valve Series
A screw-in, direct acting, poppet type
check valve. Main use is as a blocking
or load-holding device. The ICV0.
M20 allows flow passage from port
1 to 2: the cartridge has a fully gui-
ded 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). Insert type valve: the pop-
pet seals directly against the cavity.
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.
Metric cavity.
