DESCRIPTION APPLICATION
Direct 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. Good flow allows economical solutions with repeatable processes. The
capacity due to the differencial area principle, very sensitively screw-in cartridge is perfectly suitable for installation in control
adjustable. When the operating pressure adjusted by means of the blocks and is installed in sandwich- (vertical stacked systems) and
proportional solenoid is reached, the valve opens and connects the in flange plates (corresponding data sheets in this register). For
protected line with the drain to the tank. The back pressure in T (2) machining the cartridge cavity in steel and aluminum blocks, cavity
affects the pressure in P (1). For the control, Wandfluh proportional tools are available (hire or purchase). Please refer to the data
amplifiers are available (see register 1.13). sheets in register 2.13.
