The electric device of the butterfly valve adopts the frequency conversion speed regulation technology of the microcomputer, and the valve has the characteristics of multistage variable speed closing.

The valve installed in the pump outlet, can replace the gate valve (valve) and check valve two sets of valves, and the short length of the structure, double plate truss type butterfly plate, fully open when the flow resistance coefficient is less than 0.3, closed, fast, slow closing in two stages, according to different conditions, select off angle and time.
