Product Description
- Diaphragm-controlled pressure reducing valve with pre-pressure compensation for precise reduction of an inlet pressure of up to 25 bar to very low outlet pressures of 0.2 to 2 bar in industrial systems with water, steam, neutral or slightly aggressive fluidsand gases at high temperatures up to 190°C.
- The DRV 850 is a high-quality, 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 25 bar.
- It has flange connections in accordance with DIN EN 1092 PN 40 in nominal sizes DN 15 to DN 50, an integrated dirt separator, replaceable internal parts and G 1/4" pressure gauge connections on both sides.
- The valve, made entirely of stainless steel (housing 1.4408, internal parts 1.4404) with FKM seals, is designed for temperatures up to 190 °C and is particularly suitable for aggressive, hot or hygienically sensitive media.
