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 664 pressure reducing valve is a diaphragm-controlled
spring-loaded and balanced proportional control valve for large volumes
of non-hazardous media. This pressure reducer is manufactured from
deep-drawn stainless steel featuring excellent corrosion resistance. The
valve cone is fitted with a soft seal (up to 130 °C).
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 pressure range is
extremely simple and does not call for 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 valves 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 V optional IV.

Standard

» All stainless steel construction
» Quick-release body clamp ring
» Sense line connection
» Balanced cone for controlling the outlet pressure indipendently from
the initial pressure

Options

» Pressure gauge connection
» For toxic or hazardous media: additional leakage line connection. Must
be installed with a leakage line capable of draining leaking medium
safely and without pressure
» Various diaphragm and seal materials suitable for your medium
» Special connections: Aseptic, ANSI or JIS flanges, welding spigots;
other connections on request
» Special versions on request

Operating instructions, know how and safety instructions must be
observed. The pressure has always been indicated as overpressure.
