Pressure Reducing Valve Screw In Cartridge

Pilot operated 3-way pressure reducing valve of the screw-in cartridge type with thread M22x1,5 for cavity in according to ISO 7789. This valve reduces the inlet pressure to a adjustable outlet pressure. The integrated pressure relief function prevents the reduced pressure from being exceeded as a result of external forces. The valve is available with 2 types adjustments. A cover is also available for key adjustment. There are 3 pressure stages to choose from. Pressure Reducing Valve Screw In Cartridge body and adjustment spindle are galvanised. The quality of this product is redirected in the good performance data and design.

Function:

The spool, located in the pilot operated main section of the valve, is held in the reset position by a spring. The connection to the consumer is fully open. With the pilot stage which is designed as relief valve, reduced pressure is adjustable. It opens when the set value is reached. As a result, a pilot volume flows through the nozzle in the spool. The resultant pressure difference displaces the spool towards the spring. The volume flow is throttled in the valve inlet and the reduced pressure is controlled. If forces acting on the actuator allow the reduced pressure to exceed the set value, the spool is displaced until the valve inlet closes and the reduced pressure port is being connected to tank. The pressure increase is then limited.

Application:

Pressure reducing valves are used to keep the pressure constant in the consumer, irrespective of pressure fluctuations on the supply side. If there are several consumers, the pressure of the individual consumers can be set individually using the pressure reducing valve. The integrated pressure relief facility means that no additional pressure relief valve is needed in the actuator line. Installation of the screw-in cartridge in control blocks as well as in the Wandfluh sandwich plates (vertical stacked systems) and flange valves of the NG4-Mini, NG6 and NG10 types.
