The High-Performance Butterfly Valve features a double eccentric design, where the positioning of the valve shaft and disk connections causes the disk to follow a slightly eccentric path when opening. This design ensures that the disk moves out of contact with the seal as soon as it opens, minimizing friction and wear. Combined with a compensating seat design, this valve offers an extended service life and stable sealing performance. It provides excellent shutoff capabilities and corrosion protection while requiring minimal installation space.
