Valve for ex atmospheres and medium to high flow rates
Pressure reducing valves DM 652 ATEX H2
The pressure reducer DM 652 ATEX H2
was specially developed for hydrogen applications.
It is a diaphragm-controlled, spring-loaded and balanced proportional control valve for medium to large flow rates. The valve is completely made of high-quality stainless steel with excellent corrosion resistance. Since the body and the bonnet are manufactured by the deep-drawing process, the valve is very lightweight and compact.
The valve cone is soft-sealed.
