Product Usage of Cryogenic gate valves

Cryogenic gate valves for methane, liquid natural gas, hexene, carbon dioxide, liquid ammonia, liquid oxygen, liquid nitrogen, liquid hydrogen and other cryogenic media

Features of Cryogenic gate valves

1, in order to prevent the abnormal pressure in the cavity, the inlet side of the gate set pressure relief hole

2, according to the working temperature of the valve to determine the length of the top of the valve cover to ensure reliable sealing stem packing

3, according to the reasonable choice of working temperature filler, gasket and other parts of the material

4, strictly control the chemical composition of the material and low temperature impact toughness and other mechanical properties

5, using a variety of pipe flange standard and sealing surface type, suitable for a variety of engineering needs
