The bidirectional butterfly valve product structure features:
1, the butterfly valve is bi-directional under pressure, two-way metal sealing, the structure of special sealing pressure ratio can be adjusted arbitrarily, adopts eccentric s-shaped conical seat sealing surface, make the sealing surface is not easy to damage, improve the service life of the valve.
2, small operation torque, turn 90 degrees, opening and closing light quickly.
3, small flow resistance, good hydraulic characteristics, flow characteristic of approximate straight line, energy-saving effect is good, two-way seal for water flow direction.
4, reliable sealing, open/close life for more than 25000 times.
5, valve plate used in fluid mechanics performance of the double plate girder more flow design.
