The butt welded two-way hard seal disc valve is a new type of butterfly valve independently developed by our company relying on continuous innovation of science and technology. The butt welded two-way seal butterfly valve is mainly used in petroleum, chemical industry, power station, metallurgy, paper making, plumbing, light industry and other fields as a device for cutting off and adjusting on the pipeline.
Structural characteristics
Our company’s butt welding two-way pressure-bearing butterfly valve not only uses the conventional three-eccentric structure, but also combines the principle of the movable seat of the fixed ball valve, which more effectively guarantees the sealing performance of the reverse pressure, and truly achieves the two-way pressure-bearing 100%. The valve body adopts the formed seamless steel pipe assembly welding, which more effectively solves the potential external leakage problem of the casting. It has unique structure, novel design, easy opening and closing, and long service life.
