Description


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 pressure reducing valve DM 618Z ASME is a diaphragm-operated,
spring-loaded 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 316L. The valve cone is fitted with a
metallic 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.
The valve requires a sense line (to be installed on-site).
These valves are no shut-off elements ensuring a tight closing of the valve.
In accordance with DIN EN 60534-4 and/or ANSI FCI 70-2 they may feature
a leakage rate in closed position in compliance with the leakage classes III
or V.
