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

port A (1) rise. The valve functions practically independently of the blocks. For machining the cartridge cavity in steel and aluminum
pressure in port P (2). Pressure increase in the consumer port A (1) blocks, cavity tools are available (hire or purchase). Please refer to
to above the adjusted value, e.g. through an active consumer, is the data sheets in register 2.13.

avoided by discharging excess oil to the tank T (3). With the sole-
noid deenergised, the oil flows freely from port P (2) to consumer
port A (1). For the control, Wandfluh proportional amplifiers are
available (see register 1.13).
