Self-acting pressure reducers are simple control valves offering accurate
control while being easy to install and maintain. They control the pressure
downstream of the valve without requiring pneumatic or electrical control elements.
The DM 555 pressure reducing valve 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 316L featuring excellent corrosion resistance. The valve cone is fitted either with a metallic or a soft seal.
