Valve for ex atmospheres and small flow rates
Pressure reducing valves DM 505 ATEX H2
The pressure reducer DM 505 ATEX H2
was specially developed for hydrogen applications.
It is a diaphragm-controlled, spring-loaded proportional control valve for small 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.
