The pressure reducer DM 555 is a spring-loaded proportional control valve for universal application at small and medium flow rates. The valve body and medium-wetted internal parts are made of stainless steel (1.4404 / 316L) featuring excellent corrosion resistance. The valve cone is fitted either with a metallic or a soft seal.

The pressure reducer DM 755 is a diaphragm-controlled spring-loaded proportional control valve for very small outlet pressures and medium volumes. The valve body and medium-wetted internal parts are made of stainless steel 316Ti and 316L featuring excellent corrosion resistance. The valve cone is soft-seated. Millibar control valve for small to medium flow rates.
