Wafer Disc Type Soft Seal Butterfly Valve
The soft-sealed center line wafer butterfly valve has a compact structure, easy 90° rotary switch, reliable sealing, and long service life. The exterior of the butterfly valve body is sprayed with outdoor epoxy resin powder, and the casting surface treatment technology is advanced, the spraying appearance is exquisite, and the anti-corrosion performance is better. The wafer butterfly valve plate is made of SS304, SS316 stainless steel, which has excellent corrosion resistance and good intergranular corrosion resistance. The soft seal butterfly valves adopts pinless flat shaft connection, reliable transmission and two-way sealing. The wafer butterfly valve is widely used in water supply and drainage systems such as water plants, power plants, steel plants, papermaking, chemical industries, and catering, as a regulator and cut-off.
