The double soft seal design of the high-performance butterfly valve gives it zero leakage performance.

The high-performance butterfly valve can get the disk detached from the seat quickly when the valve is opened, significantly eliminating the unnecessary over extrusion and scraping between the disk and the seat, reducing the opening resistance torque as well as they wear, and increasing the seat life.

The seat design of the high-performance butterfly valve adopts different nonmetallic materials according to different customers to meet different working conditions. It can also use a soft and metal seal to make the valve fire seal by creating a double seal structure.

The external blow of the proof stem of the high-performance butterfly valve is safe and reliable and conforms
