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.
Thr pressure reducing valve DM 652 is a diaphragm-controlled, springloaded and balanced proportional control valve for universal application. This
pressure reducer is manufactured from deep-drawn stainless steel featuring
excellent corrosion resistance. The valve cone is fitted with a soft seal.
The spring module comprising spring cap, spring, adjusting screw, diaphragm and internal components, is connected to the valve body only by
means of a clamp ring and two bolts. Changing the diaphragm or the complete spring assembly for a different control range is very easy and without
special tools. The same applies to servicing and maintenance.
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, optional IV.
