Use:
Cryogenic Gate Valves are suitable for cryogenic media such as methane, liquid natural gas, ethylene, carbon dioxide, liquid ammonia, liquid oxygen, liquid nitrogen and liquid hydrogen.
Characteristic：
1. In order to prevent abnormal pressure rise in the middle cavity, pressure relief holes are installed on the inlet side of the gate.
2. Determine the top length of the valve cover according to the working temperature of the valve to ensure the reliable seal of the stem packing.
