Performance

○ Adopting flange connection, suitable for medium and large diameter ultra-low temperature pipeline systems

○ The valve body and seals are designed specifically for working conditions below -200 ℃, with reliable resistance to cold brittleness

○ Low thermal conductivity design of internal structure, effectively reducing cooling loss and frosting

○ High sealing performance ensures zero leakage operation of media such as liquid oxygen and liquid nitrogen

○ Optional explosion-proof or signal feedback function, suitable for industrial automation control needs

Application

○ LNG receiving station low-temperature flange pipeline automatic cutting and control system

○ Remote opening and closing valves of the main process pipelines for liquid oxygen and liquid nitrogen in the air separation unit

○ Ultra low temperature medium control node for liquid hydrogen refueling system in space launch site

○ Large caliber low-temperature fluid isolation device for superconducting equipment cooling circuit

○ Automatic safety interlock valve for flange connection of low-temperature storage tank inlet and outlet
