Flange ball valve temperature requirements

Flange ball valve operation and use:
1) Before the flange ball valve is operated, make sure that the pipe and valve have been flushed.
2) The operation of the flange ball valve drives the valve stem rotation according to the input signal size of the actuator: when the fan rotates 1/4 turn (90°) in the forward direction, the valve is closed. The valve opens when rotated 1/4 turn (90°) in the opposite direction.
3) Flanged ball valve 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.
