Category : Electric butterfly valve

Product Name: Central Line Soft Seat Wafer Electric ball valve

Product introduction:
As one of the most common valves the wafer type electric butterfly valve is suitable for the medium of water oil and other liquid medium. The disc supports frame structure with high strength large flow area and small flow resistance.
With whole baking finish surface the valve can effectively prevent rusting and is suited to different medium by changing high quality seal ring or seal material. The valves with two-way seal function can be installed in any direction and not be affected by the spatial position and the medium flow.
