    Triple offset butterfly valve application

    Tips: Why use a triple offset butterfly valve?

    The triple offset valve design achieves zero leakage on metal-to-metal contact. The main advantages of a triple offset butterfly valve are its conical sealing design, which results in repeatable sealing and vastly extended valve life. The hard-facing seat eliminates the rubbing between the seat and seal ring through the flow path to extend the cycle life. Its uniform sealing can operate more frequently, and open and close quickly.
