End plate
E2
is only installed with connecting plate
C2
or a central connecting plate.
Pressure reducing valve :
Limits the pressure in the block-internal EHS pilot oil
line
X
and supplies this line with the flow from the block-internal line
P
.
Pressure reducing valve switchable solenoid :
Electrical activation and
deactivation of the pressure reduction function.
The
E2
end plate without switchable solenoid (pressure reducing valve) is not
equipped with manual operating elements or external control functions.
The version with switchable solenoid (pressure reducing valve), the pressure
reduction function can be activated by energizing the switchable solenoid.
This way, the pressure in the block-internal EHS pilot oil line
X
is increased to the
pressure value of the pressure reduction function.
If the switchable solenoid is not energized, the block-internal EHS pilot oil line
X
is
relieved to the return flow.
