The reducing valve PVRM1 is a directly operated 3-way
valve controlled by proportional solenoid (1). In the
de-energized state, the spring (4) holds the control
spool (3) in relation to the housing in such a position that
the input pressure in port P is blocked, whereas the port
A is connected with tank. The electric current through
the solenoid shifts the spool and closes gradually the
return port and opens the inlet to the output port A. The
reduced pressure in port A brought to the solenoid
room acts on the differential area of the spool, this being
created by adapter (5). The solenoid pushes on the
spool with a force, which is proportional to the current.
Acting against this force is the force created by the
reduced pressure acting on the differential area. In a
balanced state, both the forces are equal. This
arrangement ensures the proportional relation between
the reduced pressure in port A and the control current.
The basic surface treatment of the solenoid is
blackened, other parts are zinc coated.
