            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
            nally to the solenoid current, the solenoid force and the pressure in   screw -in cartridge is perfectly suitable for installation in control
            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).
