Operation
The poppet remains on its
seat until the pressure drop
across the orice overcomes
the spring force over the
seat area. Full ow will then
take place from port 1 to 2.
Flow from port 2 to 1 will be
restricted by the orice.
Features
Hardened and ground working
parts extend service life.
Robust design with a 210
bar (3000 psi) max pressure
rating. Compact simple
solution in a single cartridge.

151 L/min (40 USgpm) • 210 bar (3000) psi
Description
This is a poppet type screw-in
cartridge check valve with a
by-pass orice. This will allow
free ow into an actuator while
restricting the ow out of it.
