The main body material of cast steel butterfly valve is cast steel. Drive mode can adopt manual, electric, pneumatic, gear transmission and other devices. Butterfly valves are simple in structure, small in size and light in weight. And only need to rotate 90 ° can rapid opening and closing. The operation is simple, at the same time, the valve has good flow control characteristics. When the butterfly valve is in the fully open position, the thickness of butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, and it has better flow control characteristics.
The commonly used butterfly valve has the clamp and the flanged valve two kinds. The former one is connected with a double head bolt to connect the valve between two pipe flanges. The latter is a valve with flanges, and the two ends of the valve are connected with the pipe flanges by bolts.
