Triple Offset Multilevel Seal Butterfly Valve

◆ Triple eccentric Multilevel floating sealing butterfly valve: 1. The floating metal seat design enables the seat and the sealing ring to automatically fit under the promotion of the medium, reducing the torque and extending the serve-life to achieve a bi-direction 1:1 seal. 2. The composite seal of metal and non-metal is more tightly sealed, which can realize working conditions such as high temperature and high pressure. 3.triple offset eccentric design,When the valve is switched on and off, the butterfly disc does not scratch the valve seat, and the torque of the valve stem is directly transmitted to the sealing surface through the butterfly disc, which eliminates the inability of control caused by various unstable factors such as friction in the low opening range of the valve.
