F943CX Electric Sector Blind Valve for the principle

1, the valve is opened to the valve is closed: 
Clamping motor action, driven screw for counterclockwise rotation, the valve body loose in place (indicator light shows), drive motor action, drive the counterclockwise rotation of the gate in place, the gate closed in place (Indicator light), clamping motor action, drive screw clockwise rotation, the valve body clamping in place (indicator shows) to complete the valve from opening to closing the entire process. 
2, the valve from close to open: 
clamping motor action, driven screw for counterclockwise rotation, the valve body loose in place (indicator light shows), drive motor action, drive the gate for clockwise rotation, the gate opens in place, ( Indicator shows) to complete the valve from the closed to open the whole process.
