Proportional pressure relief valves, proportional pressure reducing valves M33x2
Pilot operated proportional pressure reducing valve with integrated electronics as screw-in cartridge. Thread M22x1,5 for cavity according ti ISO 7789. The Plug & Play valves are factory set and adjusted and have a high valve-to-valve reproducibility. With protection IP67 for the electronics, these valves are suitable for-harsh environmental conditions. As standard, 4 pressure ranges are available. The adjustment takes place by a Wandfluh proportional solenoid (VDE standard 0580). The cartridge body as well as the solenoid made of steel are zinc coated and therefore rust protected.The electronics housing is made of aluminium. Optionally these valves are available with integrated controller. As feedback value generator, sensors with voltage or current output can be directly connected. The available controller structures are optimised for the utilisation with hydraulic drives.

Application
Proportional pressure reducing valves with integrated electronics are perfectly suitable for demanding applications in which the pressure frequently has to be changed. They are used in applications where high valve-to-valve reproducibility, easy installation, comfortable operation and high precision are very important. The applications are in the industrial as well as in the mobile hydraulics. The proportional pressure reducing cartridge is perfectly suitable for installation in control blocks as well as in flange and sandwich valves of the size NG10 (please refer to separate data sheets in register 2.3). 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.
