DESCRIPTION APPLICATION
Direct operated proportional pressure reducing valve in screw-in The electrical remote control in conjunction with process controls
cartridge construction for cavity according to Wandfluh standard. allows economical solutions with repeatable processes. For
Proportionally to the solenoid current, the solenoid force and the machining the cartridge cavity in steel and aluminum blocks, cavity
pressure in port A (1) rise. The valve functions practically indepen- tools are available (hire or purchase). Please refer to the data

dently of the pressure in port P (2). Pressure increase in the con- sheets in register 2.13.

sumer port A (1) to above the adjusted value, e.g. through an active
consumer, is avoided by discharging excess oil to the tank T (3).
With the solenoid deenergised, the oil flows freely from consumer
port A (1) to port T (3). For the control, Wandfluh proportional ampli-
fiers are available (see register 1.13).
