Product Description
- Diaphragm-controlled pressure reducing valve with pre-pressure compensation for reliable reduction of an inlet pressure of up to 25 bar to a downstream pressure of 1.5 to 6 bar in water- and media-neutral industrial systems with flange connection.
- The DRV 502 is a diaphragm-controlled pressure reducing valve with pre-pressure compensation for infinitely variable regulation of a back pressure of 1.5 to 6 bar at a maximum pre-pressure of 25 bar.
- It is equipped with flanges in accordance with DIN EN 1092 PN 25, has an integrated dirt trap, a replaceable cartridge and G 1/4" pressure gauge connections on both sides for the back pressure.
- The robust red brass housing with NBR seals is suitable for media-neutral applications up to 100 °C, for example in water and process engineering.
