Applications
Solenoid-Loading Relief Valve
Provides relief function from A to B of
the logic valve by connecting the X pilot
to the A port of the logic valve (shown
on the left) or by connecting the Z1 port
to the A port (shown on the right).
Using a standard directional control with
flow from P to A in the de-energized
condition will unload the valve. In the
energized state, the system will build
pressure until the relief setting is
reached. The valve can be manually
vented using the external X SAE port.
The Y port can be connected the B port
of the logic valve, but a separate drain
connection is preferred.
This configuration uses a 1:1 ratio logic
valve.
