Pressure relief cartridge direct operated
Description
Directly operated pressure relief valve in screwin cartridge construction with M22x1,5 thread for cavity acc. to ISO 7789. The valve is available with two different types of adjustment: key adjustment «S» and control knob adjustment «D». Key adjustment «S» is also available with cover, see data sheet 2.0-50. One pressure stage, 32 bar, is available as standard. The cartridge body made of steel is galvanized and therefore rust-protected.
Application
For hydraulic systems with low operating pres-sures and high volume flows to limit the operating pressure by diverting the flow of the oil from the protected line P (1) to the outlet/ tank line T ( 2). The screw cartridges are very well suited for installation in control blocks and are installed as a functioning part in Wandfluh hydraulics NG4, NG6 and NG10 sandwich plates (vertical stacking) and flange valves (please see separate data sheets in register 2.1). Cavity tools are available (for hire or purchase) for the manufacture of cartridge cavities in steel or aluminium blocks. See data sheets in register 2.13. Attention: Should therefore not be utilized anymore in applications with periodically changing direction of flow.
