DESCRIPTION APPLICATION
Pilot operated proportional pressure relief valve in screw-in The electrical remote control in conjunction with process controls
cartridge construction for cavity according to ISO 7789. High flow allows economical solutions with repeatable processes. The
capacity, very sensitively adjustable. When the operating pressure screw-in cartridge is perfectly suitable for installation in control
adjusted by means of the proportional solenoid is reached, the blocks and is installed in sandwich- (vertical stacked systems) and
valve opens and connects the protected line with the drain to the in flange plates (corresponding data sheets in this register). For
tank. The back pressure in T (2) affects the pressure in P (1). For the machining the cartridge cavity in steel and aluminum blocks, cavity
control, Wandfluh proportional amplifiers are available (see tools are available (hire or purchase). Please refer to the data

register 1.13). sheets in register 2.13.
