Our standard product range comprises fittings for hydrogen and other gases at ambient and cryogenic media temperature, with highly precise control valves, globe valves, check valves and blow-off valves as well as strainers for installation in valve boxes, fitted in vacuum jackets or regular installation into pipes. Cryogenic temperature down to 2 K, high operating pressure up to 1,000 bar, high leak tightness to outside, low heat input, media compatibility and short shutter speed characterize our products. There is a long track record especially for hydrogen applications. All body types are made of full stainless steel and sealed with bellows. STÖHR valve sizes range from small ("XXS" starting with DN4) to "XXL" (DN300).
