Proportional pressure relief valves, proportional pressure reducing valves M22x1,5
Pilot operated proportional pressure reducing valve with integrated electronics as a screw-in cartridge. Thread M22x1,5 for cavity according to ISO 7789. These plug & play valves are factory set and adjusted. High valve-to-valve reproducibility. Housing for electronics with protection class IP67 for harsh environment. Seven standard pressure levels are available. Adjustment by a Wandfluh proportional solenoid (VDE standard 0580). The cartridge and the solenoid made of steel are zinc coated and therefore rustprotected. The housing for the elctronics 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.
Proportional pressure reducing valve
- Integrated amplifier or controller electronics
- Pilot operated
- Qmax = 60 l/min
- pmax = 400 bar
- pN red max = 350 bar
Proportional pressure reducing valves with integrated electronics are well suited for demanding applications, in which the pressure frequently has to be changed. They are imple-mented in systems calling for good valve-to-valve reproducibility, easy installation, comfort-able operation and high precision in industrial hydraulics as well as in mobile hydraulics. The integrated controller reliefs the machine control system and operates the pressure regulation in a closed control loop. The proportional pressure reducing cartridge is very suitable for mounting in control blocks, flange bodies and sandwich plates of the size NG4-Mini, NG6 and NG10. (Please note the separate data sheets in register 2.3). Cavity tools are available for machining the cavities in steel and aluminium (hire or purchase). Please refer to the data sheets in register 2.13.
