Cryogenic valves are very similar to conventional valves, with the exception of materials and features such as an extended stem. These extended stems allow handles or actuators to be at an ambient temperature.
Cryogenic valves normally refer to valves with working temperature below -110°C, widely used in industrial gas, LNG, LPG and other low temperature applications and regulating or controlling the flow of cryogenic gases, slurries or liquids at low temperatures. These valves come in different shapes and sizes so that they can handle different pressures required by various applications. Some of the common types of cryogenic valves are butterfly valves, relief valves, ball valves and globe valves. The user can manually operate or automate cryogenic valves to handle large systems.
During operation, if it is found that the operation is too laborious, the cause should be analyzed. If the packing is too tight, it can be properly relaxed. If the valve stem is skewed, the personnel should be notified to repair it. In some shut-off valves, when the closing member is heated, the closing member expands due to heat, which makes it difficult to open; if it must be opened at this time, the valve cover can be loosened by half a turn to one turn to eliminate the valve stem stress, and then the handwheel is moved.
