1. The butterfly valve is a two-way pressure bearing and two-way metal seal. The special structure can adjust the sealing pressure at will. The eccentric S-shaped conical valve seat sealing surface is used to prevent the sealing surface from being damaged and improve the service life of the valve.

2. The operating torque is small, and it can be opened and closed at 90 degrees, which is light and fast.

3. Small flow resistance, good hydraulic characteristics, flow characteristics approximate to inclined straight line, good energy saving effect, two-way sealing has no direction requirements for water flow.

4. The seal is reliable, and the opening and closing life is more than 25000 times.

5. The valve plate adopts the double plate truss type multi channel design which conforms to the hydrodynamic performance.
