Pilot operated proportional pressure relief
valve with inverse function. Thread M22x1,5
and cavity according to ISO 7789. As standard
versions, 7 pressure levels are available. The
differential area between the seat diameter
and the poppet guide diameter determines
the pressure level. Flat pressure volume
flow characteristic. The regulation is effected
through a Wandfluh proportional solenoid.
The cartridge body and the solenoid made of
steel are zinc coated and thus rust-protected.
Wandfl uh proportional amplifiers are needed
to control the proportional pressure relief valve
(register 1.13).
