Features:
The cast iron wafer type butterfly valve is a double-headed bolt connecting the valve between two pipe flanges. It has a simple structure and only consists of a few parts. The cast iron wafer type only needs to be rotated 90° to complete the opening and closing. It is simple to operate and at the same time, the cast iron wafer type is Butterfly valves have good fluid control characteristics.
1. The butterfly valve lever has a simple structure, flexible, labor-saving and convenient operation.
2. The wafer-type butterfly valve has a sealing function that becomes tighter the closer it is closed, and the sealing performance is reliable.
3. The butterfly plate of the wafer butterfly valve adopts a frame structure, which has high strength, large flow area and small flow resistance.
4. The entire wafer butterfly valve is painted, which can effectively prevent rust and different media can be used as long as the sealing material of the valve seat is replaced.
5. The wafer butterfly valve has a two-way sealing function. When installed, it is not controlled by the flow direction of the medium and is not affected by the spatial position. It can be installed in most directions.
