Electric Actuator Diaphragm Valve

The KOSEN Electric Actuator Diaphragm Valves is composed of a valve body, a valve cover, a valve stem, a disc, a diaphragm, an electric device and other driving parts.The opening and closing of the valve is driven by the connecting shaft of the electric device to drive the stem nut, so that when the valve rod moves axially, the valve flap can be driven up and down to achieve. When the power supply breaks down and the valve is in urgent need of opening and closing, the hand - electric handoff handle should be first converted to the manual marked position, and the flash door can be opened and closed through the rotating handwheel. When rotating clockwise, the valve can be turned off; otherwise, it will turn on. When the electric operation is resumed, the switch handle must be switched to the position marked with electric mark, so that the electric operation can be carried out.
