CV3-4 - Check valve
Direct acting, poppet type
7.6 L/min (2 USgpm) • 350 bar (5000 psi)
Operation
The valve remains closed until
the spring bias is reached
at port 1 at which time the
poppet lifts of the seat and
allows ow from port 1 to port
2. in the other direction the
valve is closed.
Features
Compact screw in cartridge
design. Hardened and ground
working parts to limit leakage
and extend service life.
Descriptions
This is a compact Poppet Type
check valve ideal for use in
manifolds for load sense or
low ow applications.
