Since the 1960s Stoehr have specialised in the development and manufacture of cryogenic valves for gases and liquids. They predominantly work for the industrial & specialty gases, aerospace, marine technology, energy technology and chemical industries, and in the field of science and research.
The Stoehr product range of standardised ambient and cryogenic valves and gas filters in sizes from DN4 to DN300 include high-precision control valves, shut-off valves, check and blow-off valves and gas filters for installation in valve boxes, in vacuum-jackets or in conventional pipes. Body types with housings in straight or angle shape are made of high-grade or special stainless steel and sealed with bellows.
These control valves are designed for extreme operating conditions. Cryogenic temperatures of down to 4K or below for processing liquid helium, high pressure levels of up to 1,000 BAR, high leak tightness to the atmosphere, compatibility with aggressive media requirements, and short opening and closing times are all examples of the demands handled by Stoehr.
