The characteristics and applications of the pneumatic control valve in low temperature

Cryogenic pneumatic control valve is a low temperature, cryogenic occasions 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. Widely used in metallurgy, cryogenic air separation, oxygen, petroleum, chemical industry, and the cryogenic occasion. 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.
