High-Performance & Triple-Offset Butterfly Valves

As a leading manufacturer of high-performance butterfly valves in China, TWIV delivers heavy-duty sealing solutions engineered specifically for demanding applications, ensuring exceptional "zero-leakage" performance even under extreme industrial pressures and temperatures. Our specialized series of triple-offset butterfly valves are custom-designed to offer performance and longevity that far exceed those of traditional valves, providing an ideal—and both cost-effective and space-efficient—alternative for a wide range of severe service environments.

Thanks to an integrated, optimized, and friction-free sealing design, every TWIV triple-offset butterfly valve completely eliminates component wear caused by friction during valve opening and closing cycles. This design not only significantly reduces operating torque and extends service life but also ensures reliable bi-directional shut-off capabilities. For international procurement managers and EPC contractors in sectors such as power generation, chemicals, oil & gas, and heavy-duty water treatment, TWIV butterfly valves represent the ultimate, preferred solution.
