Pressure relief, backpressure, pressure sequence, accumulator unloading valves M22x1,5
Pilot operated pressure relief valve as screw- in cartridge with thread M22x1,5 for cavity according to ISO 7789. The valve is designed according to AD-2000 and EU-type tested in accordance with the Pressure Equipment Directive 2014/68/EU. As standard versions, the following preferential response pressures are available: 100, 140, 250, 330 and 350 bar. Apart from this, within the range of 50–350 bar response pressures can be freely selected. The cartridge body and the cover made of steel are zinc coated and therefore protected against rust and the blue locking seal made of plastic provide this quality product with a clean design.

Application
For the protection of the maximum permissible operating pressure in hydraulic systems with pressure accumulators, resp. pressure reservoirs by the flowing out of the oil from the protected oil line P (1) to the tank line T (2). The screw-in cartridge is very suitable for mounting in control blocks and is built into the Wandfluh hydraulics NG6 and NG10 as a functional element in sandwich style plates (vertical combination) and flange-mounted valves (please refer to the separate data sheets in register 2.1). Stepped tools are available for making the receptacle bores in steel and aluminium (hire or purchase). Please refer to the data sheets in register 2.13. Attention: The banking-up pressure in the tank line for Qmax must amount to a maximum of 3 bar.
