Two-way pressure butterfly valve features and technical functions
1. The butterfly valve is bi-directionally pressurized, bi-directional metal hard seal and sealed. The special structure can adjust the sealing specific pressure arbitrarily. The eccentric S-shaped conical seat sealing surface is used to make the sealing surface not easy to damage and improve the service life of the valve.
2, the operating torque is small, turn 90 degrees to open and close, light and fast.
3. The flow resistance is small, with good hydraulic characteristics, the flow characteristics are approximately inclined straight line, the energy saving effect is good, and the two-way sealing has no direction requirement for water flow.
4, reliable sealing, corrosion resistance, wear resistance, high temperature resistance, long service life.
5. The butterfly valve plate adopts a streamlined design with high strength, large flow area, small flow resistance and energy saving.
