Product Description
- Piston-controlled pressure reducing valve with pre-pressure compensation for precise reduction of an inlet pressure of up to 40 bar to an adjustable outlet pressure of 2.0 to 20 bar – particularly suitable for water, neutral fluids and, with high flow rates, also for compressed air, nitrogen and other non-flammable gases.
- The DRV 425 is a piston-controlled pressure reducing valve with pre-pressure compensation for infinitely variable regulation of a back pressure of 2.0 to 20 bar at a maximum pre-pressure of 25 bar.
- It features external threads in accordance with ISO 7, an integrated dirt trap, replaceable cartridge and G 1/4" pressure gauge connections on both sides for monitoring the back pressure.
- The robust red brass housing with NBR seals is designed for operating temperatures up to 100 °C and is suitable for water, neutral liquids and non-flammable gases.
