The high-performance butterfly valve adopts a double eccentric butterfly plate with a spherical sealing surface, equipped with a single flexible lip seal seat, suitable for occasions that require reliable sealing and adjustment characteristics. Due to the design of the double eccentric butterfly plate, it has tight sealing performance and a long service life. It can be used for quickly cutting off or adjusting flow, and is suitable for transporting liquids and gases (including steam) in various industrial pipelines.

The high-performance butterfly valve adopts the three-dimensional eccentric principle, which idealizes the spatial motion trajectory of the sealing surface. The sealing surfaces have no friction or interference with each other, and the sealing material selection is appropriate, which makes the sealing performance, corrosion resistance, high temperature resistance, and wear resistance of the butterfly valve reliable. Can be used for media such as chlorine, oxygen, high vacuum, sulfur resistant or corrosive media

High performance butterfly valves have fire-resistant structures to choose from. The connection method can be clamp type or lug type single flange used for large pipe diameters and pipeline terminations. Mainly suitable for drainage systems in water plants, power plants, steel plant smelting, chemical industry, water source spring engineering, environmental facility construction, etc., especially suitable for use in waterway pipelines as regulating and intercepting equipment.
