1) Before operation, ensure that the pipeline and valves have been flushed.
2) Valve operation is completed by rotating the valve stem according to the input signal of the actuator: a 1/4 turn (90°) clockwise rotation closes the valve. A 1/4 turn (90°) counterclockwise rotation opens the valve.
3) When the actuator's 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.
