Application
The modular or sandwich valve is
stacked along with directional valves
in CETOP 3 interfaces to provide a
check valve system in various ports
depending on the configuration. The
valve can be used to either prevent
pressure spikes in the main pressure
port ‘P’ or the actuator ports ‘A’ and ‘B’.
Operation
As with all direct acting relief valves,
when the pressure at P or A and/or B
exceeds the spring force, the poppet
shifts backward opening the radial
holes and allowing the to the Tank
Port. The pressure can be set by
adjusting the tension in the spring.
Features
Sandwich construction offers a
compact solution. Hardened working
parts ensure a long, reliable and
trouble-
free life. The cartridge
construction gives flexibility in
servicing..
