APPLICATION
The valve is used to limit the pressure in the system.
This economical solution for small flow systems is also
suited for pilot systems. Being a direct operated, zero
leak valve and its compact nature, the valve finds
applications in most hydraulic systems.
OPERATION
As with all direct acting relief valves, when the pressure
at the Pressure Port (1) exceeds the spring force, the
poppet shifts backward allowing the flow from the
Pressure Port (1) to the Tank Port (2). The pressure
can be set by the adjuster screw on top of the valve.
FEATURES
Hardened, match ground and honed working parts give
a long, trouble-
free service life. The valve provides a
consistent and stable operation with a low pressure ri
se
due to increasing flow. Cartridge construction allows for
maximum flexibility in mounting.
