CVH0.S08 Valve Series
A screw-in, cartridge style, direct
acting, ball type check valve. Main use
is as a blocking or load-holding device.
The CVH0.S08 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 pla-
ted and corrosion-proof. All valve par-
ts are made of high strength steel.
Compact size.
