Large-Diameter Butterfly Valve Manufacturer

Tianjin TWIV Fluid Valve Company specializes in the design and manufacturing of large-diameter butterfly valves, dedicated to meeting the most demanding industrial fluid control requirements. Our product range covers a wide spectrum of nominal diameters—reaching up to DN3600—ensuring reliable operational performance in large-scale infrastructure projects, municipal water supply mains, power plant circulating water systems, and desalination facilities.

 One-Stop Solutions for Your Engineering Designs

Our large-diameter butterfly valves are available in various structural configurations, including double-flanged, U-type, and concentric designs. To ensure structural integrity under high-pressure and high-flow conditions, we utilize premium manufacturing materials such as Ductile Iron (DI), Cast Steel (WCB), Stainless Steel (SS304/SS316), Bronze, and Alloy Steel. Each valve is precision-engineered to minimize fluid pressure drop while achieving a tight, zero-leakage shut-off at both the valve body and sealing interface.

 Customized Services Tailored to Your Needs

Actuation Options: Can be equipped with high-torque worm gearboxes, electric actuators, or pneumatic actuation systems for effortless and convenient operation.

 Corrosion Resistance: Optional epoxy resin coatings and specialized liners (such as EPDM, NBR, or PTFE) are available, making them particularly suitable for applications involving seawater desalination and wastewater treatment.

 Standard Compliance: Manufactured in strict adherence to international standards such as AWWA C504, API 609, and EN 593.
