Principle of Flanged Triple Offset Butterfly Valve

The pressure on its sealing surface is produced by the torque of the transmission and the action of the dielectric pressure on the valve plate. When the pressure of positive medium increases, the tighter the pressure between the disc oblique cone surface and the seat sealing surface, the better the sealing effect. When in reverse flow mode, the sealing between the disc and seat is driven by the torque of the actuator to force the disc towards the seat. As the pressure of the reverse medium increases, the unit positive pressure between the valve plate and the seat is less than the pressure of the medium.
