Two operating modes of LNG shut-off valve

LNG shut-off valve is not a relatively common type of shut-off valves, but it is considered more advanced in design and standards. According to the development in recent years, the LNG shut-off valve currently has two operating modes, which are automatic adjustment and manual operation.

Among them, the automatic operation of LNG shut-off valve adopts a combination of actuator and valve, and the more commonly used ones are pneumatic and hydraulic.

Electric etc. Since this type of LNG shut-off valve is a driving source that controls the opening and closing of the valve by the actuator mechanism, the operation of the LNG shut-off valve in the pipeline can be said to be automated.

There are several ways to drive the gas gate valve

For manually operated LNG shut-off valves, the size of the handle and handwheel is taken into consideration when designing it. Therefore, in use, it stipulates that operators shall not use tools such as wrenches to operate the LNG shut-off valve. However, if two or more people operate together, the diameter of the handwheel must be greater than 320mm to be able to bear it.
