Valve for ex atmospheres and small flow rates
Back pressure regulators UV 3.5 ATEX H2
The back pressure regulator UV 3.5 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 has either a soft or a metallic seal (setting range 10 – 20 bar only soft-sealed).
