The three-eccentric butterfly valve, through a three-layer eccentric design, enables the butterfly plate to come into instantaneous contact with the valve seat without friction when opening and closing, significantly extending the sealing life. Viti's three eccentric butterfly valve adopts a special hard alloy surfacing sealing pair, achieving bidirectional high pressure and zero leakage. It is an ideal choice for critical working conditions such as petrochemicals and long-distance pipelines.
