◆ Triple eccentric PTFE soft sealing butterfly valve. On the basis of the double eccentric butterfly valve, the eccentric soft sealing butterfly valve which is easy to maintain is further improved. Its structural feature is that the axis of the valve stem deviates from the center of the butterfly plate, and also deviates from the center of the body and the valve seat. The effect of the triple eccentric PTFE soft sealing butterfly valve enables the butterfly plate to be released from the valve seat immediately after the valve is opened, which greatly eliminates unnecessary excessive extrusion and scratching of the butterfly plate and the valve seat, reduces the opening resistance and reduces It reduces wear and improves the life of the valve seat.

Design Feature+

◆ The hard-sealed butterfly valve adopts three eccentric designs and has a tighter sealing function.

◆ The sealing ring is made of PTFE, and the elastic seal has excellent sealing performance, corrosion resistance and easy maintenance.

◆ It can be designed to have a two-way sealing function, and it is not restricted by the flow direction of the medium during installation, and is not affected by the spatial position. It can be installed in any direction.

◆ The driving device can be installed in multiple positions (rotated by 90° or 180°), which is convenient for users to use.

◆ Widely used in petroleum, chemical, electric power, metallurgy, food, medicine, textile, paper and other industries
