DN80 Flanged Discharge Ball Valve uses a ball with a circular through hole as the opening and closing part. The ball is driven by the valve stem to rotate 90 degrees around the center of the valve stem to complete the opening and closing function. It is made of forged or seamless pipes and steel plates made of high-quality stainless steel materials and welded as a whole, which avoids any possible leakage of media. The strength, safety, and resistance to harsh environments of the ball valve have been specially considered during design and are suitable for various corrosive and non-corrosive media.
