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 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.
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.
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, optional IV.
