Direct operated proportional pressure relief
valve with inverse function. Thread M22x1,5
for cavity according to ISO 7789. As standard
versions, 7 pressure ranges are available: 20,
40, 63, 100, 160, 200, 315 bar. Good flow performance
due to the differential area principle.
Small leak along the poppet guide. Adjustmend
by a Wandfluh proportional solenoid.
The cartridge and the solenoid made of steel
are zinc coated and therefore rust-protected.
Wandfluh proportional amplifiers are needed
to control the proportional pressure relief valve
(register 1.13).
