High pressure valve for ex atmospheres and small to medium flow rates
Pressure reducing valves DM 510, 514 ATEX H2
The DM 510, 514 ATEX H2 pressure reducing valves
was specially developed for hydrogen applications.
They are diaphragm, piston or bellows-controlled spring-loaded proportional control valves for high inlet and outlet pressures.
They can be supplied with three types of connections: sockets, flanges and welding spigots. Each size of valve may be fitted with three different seats. The valve cone may be fitted with a soft or metallic seal.
