Millibar valve for potentially explosive atmospheres
Pressure reducing valves DM 762 ATEX

The pressure reducer DM 762 ATEX
is a diaphragm-controlled spring-loaded proportional control valve for very small outlet pressures and medium volumes in potentially explosive atmospheres.
This pressure reducer is manufactured from deep-drawn stainless steel (1.4404 / 316L) featuring excellent corrosion-resistance.
The valve cone is fitted with a soft seal.

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 762 ATEX pressure reducing valve is a diaphragm-controlled
spring-loaded proportional control valve for very small outlet pressures and
medium volumes in potentially explosive atmospheres. This pressure reducer is manufactured from deep-drawn stainless steel featuring excellent
corrosion resistance. The valve cone is fitted with 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.
The valve requires a sense line (to be installed on-site).
We recommend that G 1 and G 1½ or DN 25 and DN 40 connections be
used.
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.
