Double Flanged Butterfly Valves boast a unified one-piece body configuration featuring flanges at both ends, enhancing resistance for dead-end service. The distinctive strength of these TTV Butterfly Valves lies in their face-to-face interchangeability, adhering to international standards not only for Butterfly Valves but also extending compatibility to some Gate Valves. This design offers end-users a broader spectrum of options when replacing existing valves in the pipeline. The substitution of outdated Gate Valves with Butterfly Valves has become a prevalent practice in specific applications.
