Metallurgy / Oil Engineering Triple Offset Butterfly Valve Bidirectional Zero Leakage

YSMETER Triple Offset Butterfly Valve

Triple Offset Butterfly Valve, both valve disc and three sealing ring are designed in special three eccentric structure,with characteristics of impact structure, good shut-off performance and long operation life etc, so it has both regulating and shut-off functions; Due to the adoption of the three eccentric structure design, when it is  opening and closing, the valve plate and the sealing ring can be quickly disengaged (without friction design), which effectively prevent the seal ring from wearing; The valve seat and the sealing ring adopt the replaceable structure design, allowed client to repair and replace conveniently; Its low torque advantage, can really realize the bidirectional zero leakage, small flow resistance and large rated flow coefficient which could be widely used to cut off and regulate the processing fluids, such as metallurgy, oil,chemical engineering,electric power,natural gas.
