DESCRIPTION ​ APPLICATION ​
Pilot operated proportional pressure reducing valve in screw-in car- The electrical remote control in conjunction with process controls
tridge construction for cavity according to ISO 7789. Proportionally to allows economical solutions with repeatable processes. The scr-

rise. The valve functions practically independently of the pressure in and is installed in sandwich- (vertical stacked systems) and in flange
port P (2). Pressure increase in the consumer port A (1) to above the plates (corresponding data sheets in this register). For machining the
adjusted value, e.g. through an active consumer, is avoided by cartridge cavity in steel and aluminum blocks, cavity tools are availa-
discharging excess oil to the tank T (3). With the solenoid deenergi- ble (hire or purchase). Please refer to the data sheets in register 2.13.​
sed, the oil flows freely from consumer port A (1) to port T (3). For the
control, Wandfluh proportional amplifiers are available (see register
1.13). ​​​
