DESCRIPTION APPLICATION
Direct operated, pressure compensated proportional flow control Proportional flow control valves with integrated electronics are
valve as screw-in cartridge for cavity according to ISO 7789. With perfectly suitable for demanding applications in which the volume
the solenoid deenergised, the control spool is held in the closed flow frequently has to be changed. They are used in applications
position by a spring. The change of the electric current is followed where high valve-to-valve reproducibility, easy installation, com -
by a proportional volume flow change. From the input (1), the fluid fortable operation and high precision are very important. The inte-
flows over the control and throttling spool to the controlled output grated controller reliefs the machine control and operates the volu-
(2). The control takes place via an analogue interface or a fieldbus me flow control in a closed loop circuit. For machining the cartridge
interface (CANopen, J1939 or Profibus DP). The parameterisation cavity in steel and aluminum blocks, cavity tools are available (hire
takes place by means of the free of cost parameterisation and dia- or purchase). Please refer to the data sheets in register 2.13.

Wandfluh proportional amplifiers are available (see register 1.13).
