Pressure Reducing valve DM 618 for medium to high flowrates

The pressure reducing valve DM 618 is a diaphragm-operated, springloaded and balanced proportional valve for high flow rates.
The valve body is made of cast steel. Diaphragm housing, bonnet and internal parts are made of stainless steel 1.4404 (316L). The valve cone is fitted with a soft seal.The outlet pressure to be controlled is balanced across the control unit by the force of the valve spring (set pressure). As the outlet pressure rises above the pressure set using the adjusting screw, the valve cone moves towards the seat and the volume of medium is reduced. As the outlet pressure drops, the valve control orifice increases; when the pipeline is depressurised, the valve is open. Rotating the adjusting screw clockwise increases the outlet pressure.
