Characteristics / Ordering Code
Proportional pressure reducing valves series PRPM keep
a constant pressure p
red
on the secondary side – inde-
pendent of pressure uctuations on the primary side. The
integrated pressure relief function obviates the need for
an additional pressure relief valve on the secondary side
and reliefs to tank, if the reduced pressure rises above
the setting pressure.
The proportional pressure reducing valve reduces the
pressure in output port p
red
in proportion to the solenoid
current. The PRPM works practically independent of the
inlet pressure. In non-activated mode, the connection to
the tank is fully open with a min. pressure corresponding
to the spring force.
The gauge port is connected to the secondary side. Types
A and B have an integrated bypass check valve. The
PRPM provides optimum performance in combination
with a digital amplier module PCD00A-400.
