Pneumatic - valve pneumatic control valve is a cryogenic situations at low temperature

Cryogenic pneumatic control valve is cryogenic occasion use pneumatic - valve cryogenic pneumatic control valve is a kind of low temperature, cryogenic circumstance using pneumatic control valve. The long neck cover insulation, with many spring actuator, with the overall structure is compact, light weight, good stability, etc. Body structure of precision casting Angle, materials for aluminum alloy, with good low temperature resistance. Bellows seal to ensure the pneumatic control valve in the occasion where it in low temperature. Therefore widely used in metallurgy, cryogenic air separation, oxygen, petroleum, chemical industry, and cryogenic circumstance. Special used for precise control of low temperature gas, fluid ( Such as liquid oxygen, liquid argon, etc. ) The process parameters in a given constant value. Use pneumatic - valve for installation the note 1 at low temperature, low temperature pneumatic control valve should be stored in dry room and pathways, both ends must be blocked. No deposit piled up. 2, long-term storage of pneumatic control valve should be checked regularly, remove dirt, in all the moving parts and processing surface should be coated with anti-rust oil, prevent rust. 3, pneumatic control valve should be installed in horizontal pipe runs at low temperature, vertical installation required. Valve lever up. 4, required by this arrow and the medium for installation. The major parts material.
