DESCRIPTION APPLICATION
Direct operated proportional pressure reducing valve with inverse These valves are used in hydraulic systems where the pressure
function in screw-in cartridge construction for cavity according to has to be changed frequently. The electrical remote control in
Wandfluh standard. The proportional pressure reducing valve conjunction with process controls allows economical solutions
controls the pressure in port A (1). With the solenoid deenergised, with repeatable processes. For machining the cartridge cavity in

maximum working pressure is present. If the solenoid current steel and aluminum blocks, cavity tools are available (hire or
increases, the pressure in port A drops (1). The valve operates purchase). Please refer to the data sheets in register 2.13.
practically independently of the pressure in port P (2). Pressure
increase in port A (1) to above the adjusted value, e.g. through an
active consumer, is avoided by discharging excess oil to the tank
(3). For the control, Wandfluh proportional amplifiers are available
(see register 1.13).
