Operation of fixed ball valve flanged end

1. Make sure that the pipeline and fixed ball valve have been flushed before operation.

2. The operation of the valve drives the rotation of the valve stem according to the size of the input signal of the actuator: when the forward rotation is 1/4 turn (900), the valve is closed. When rotating 1/4 turn (900) in the reverse direction, the valve opens.

3. When the direction indicator of the actuator is parallel to the pipeline, the valve is open; when the arrow is perpendicular to the pipeline, the valve is closed.
