DESCRIPTION
Pilot operated proportional pressure reducing valve in screw-in
cartridge construction for cavity according to ISO 7789. Proportio-
nally to the solenoid current, the solenoid force and the pressure in
port A (1) rise. The valve functions practically independently of the
pressure in port P (2). Pressure increase in the consumer port A (1)
to above the adjusted value, e.g. through an active consumer, is
avoided by discharging excess oil to the tank T (3). With the sole-
noid deenergised, the oil flows freely from consumer port A (1) to
port T (3). For the control, Wandfluh proportional amplifiers are
available (see register 1.13).
APPLICATION
The electrical remote control in conjunction with process controls
allows economical solutions with repeatable processes. The
screw-in cartridge is perfectly suitable for installation in control
blocks and is installed in sandwich- (vertical stacked systems) and
in flange plates (corresponding data sheets in this register). For
machining the cartridge cavity in steel and aluminum blocks, cavity
tools are available (hire or purchase). Please refer to the data
sheets in register 2.13.
