GAS Cartridge - 350 bar
Direct acting - Poppet type
A screw-in, direct acting, ball type
in-line check valve. Main use is as
a blocking or load-holding device.
The CVB0 allows flow passage from
port 1 to 2: the cartridge has a fully
guided check which is spring-bia-
sed closed until sufcient pressu-
re is applied at port 1 to open to 2.
The flow is blocked in the opposite di-
rection (2 to 1).
External surfaces are oxide burnished and
corrosion-protected. All valve parts are made
of high strength steel. Reversed installation is
possible (except for size G18) yet not recom-
mended.
