VH011
A screw-in, cartridge style, direct
acting, poppet type check valve.
The CVS4.S10 allows flow pas-
sage from port 1 to 2: the cartrid-
ge has a fully guided check which
is spring-biased closed until suf-
cient pressure is applied 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 cor-
rosion-proof. All valve parts are made of high
strength steel. Poppet is hardened and ground
to guarantee minimal wear and to extend ser-
vice life. Compact size. Optional bias sprin-
gs for back-pressure application flexibility.
