1) Confirm that the pipeline and valve have been flushed before operation;

2), the operation of the valve according to the size of the input signal of the actuator to drive the valve stem to complete: when the forward rotation of 1/4 turn (900), the valve is closed. When the 1/4 turn (900) is rotated in the reverse direction, the valve is opened;

3) When the actuator direction indicator arrow is parallel to the pipeline, the valve is open; when the indicator arrow is perpendicular to the pipeline, the valve is closed. Stainless steel ball valves are widely used in petroleum, chemical, power generation, papermaking and other departments, as well as people's daily lives.
