Product Description
- Diaphragm-controlled pressure reducing valve with pre-pressure compensation for precise reduction of an inlet pressure of up to 16 bar to very low outlet pressures of 0.2 to 2 bar in systems with water, compressed air or neutral fluids with low pressure requirements.
- The DRV 450 is a diaphragm-controlled pressure reducing valve with pre-pressure compensation for infinitely variable adjustment of a low back pressure of 0.2 to 2 bar at a maximum pre-pressure of 16 bar.
- It features external threads in accordance with ISO 7, an integrated dirt trap, a replaceable cartridge and G1/4" pressure gauge connections on both sides for the back pressure.
- The housing is made of red brass, the media-contacting internal parts are made of Hostaform C and brass (from DN 40 only brass) and the valve is suitable for water temperatures from -15 °C to +100 °C.
