The pressure reducer DM 462
is a twin seat diaphragm-controlled spring-loaded proportional control valve which is primarily used for hygienic applications in the food processing and pharmaceutical industries.
A PTFE protective film renders the diaphragm physiologically safe and steamproof up to 180 °C. The valve cone is fitted with a soft seal. The valve does not require an external pilot line.
This valve is manufactured from deep-drawn stainless steel featuring excellent corrosion resistance. It contains virtually no dead pockets and is suitable for use in CIP and SIP systems. The angled design allows complete draining.

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 is a twin seat diaphragm-controlled springloaded proportional control valve which is primarily used for hygienic applications in the food processing and pharmaceutical industries. A PTFE protective foil renders the diaphragm physiologically safe and steamproof up to
180 °C. The valve cone is fitted with a soft seal. The valve does not require
an external pilot line.
This valve is manufactured from deep-drawn stainless steel featuring excellent corrosion resistance. It contains virtually no dead pockets and is suitable
for use in CIP and SIP systems. The angled design allows complete draining.
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.
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.
