Name: High-Performance Metal Seat Butterfly Valve
Brand: Lotoke
SKU: 134712678

◆ New lotoke double eccentric high-performance metal to metal butterfly valve is further improved on the basis of the single eccentric butterfly valve. Its structural feature is that the axis of the valve stem deviates from the center of the butterfly plate and the center of the body. The double eccentric effect 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, reduces wear and improves The life of the valve seat is improved. The scraping is greatly reduced, and the double eccentric butterfly valve can also use metal seat, which improves the application of the butterfly valve in the high temperature field.

Design Feature+

◆ Reasonable design, compact structure, easy assembly and disassembly, and easy maintenance.

◆ The eccentric structure is adopted to reduce the friction of the sealing ring and prolong the service life of the valve.

◆ Completely sealed, zero leakage. Can be used in ultra-high vacuum conditions

4 Replace the valve plate sealing ring, butterfly plate, shaft and other materials, which can be applied to a variety of media and different temperatures
