Operation: Before formal operation, it is necessary to confirm whether the pipeline and valve have completed the cleaning work. The valve operation needs to drive the valve stem to rotate according to the size of the actuator input signal. If the direction indicator tip of the actuator is parallel to the pipeline, it means that the valve is open; If the pipeline is perpendicular to the indicating arrow, it means that the valve is closed.

How to use explosion-proof electric ball valve? The explosion-proof electric ball valve will rust during use. Through metallographic analysis, dyeing test surface, heat treatment test surface, SEM and other experimental analysis, it is found that the key factor of data corrosion is that the data are separated from the carbide at the grain boundary, forming anoxic valve, gate valve, stop valve and ball valve.
