Millibar control valve for medium to very high flow rates
Pressure reducing valves RP 840
The pressure reducer RP 840
is a pilot-operated control valve consisting of a main valve for high flow rates combined with a millibar valve serving as pilot valve.
Both valves are manufactured from deep-drawn stainless steel featuring excellent corrosion resistance and are arranged as a pre-mounted unit in a rack.
The valve cone is soft-sealed.
