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 0.5 to 9 bar in industrial systems with flange connection that carry water and neutral media.
- The DRV 578 is a diaphragm-controlled pressure reducing valve with pre-pressure compensation for infinitely variable adjustment of a back pressure of 0.5 to 9 bar at a maximum pre-pressure of 25 bar.
- It has flange connections in accordance with DIN EN 1092 PN 25, an integrated dirt trap, a replaceable cartridge and G 1/4" pressure gauge connections on both sides for monitoring the back pressure.
