High Performance Butterfly Valve

This high performance butterfly valve is a professional-grade valve for demanding jobs. It performs better than standard butterfly valves in pressure, sealing, and service life. The valve uses a double-offset or triple-offset design. The shaft is offset from both the valve center and the seat center. This design makes the disc lift off the seat quickly as it opens. This reduces friction and wear. Our product gives you zero leakage in both directions. It lasts much longer than standard valves. We make the valve body from carbon steel, stainless steel, or alloy steel. We select the material based on your process conditions. Our product meets Class 150 and Class 300 pressure ratings. We have supplied these valves for oil refineries, power plants, and chemical plants worldwide. A maintenance manager at a Chinese petrochemical plant said our product ran for three years without any seat replacement. That is a real-world result we are proud of.

This high performance butterfly valve gives you a choice of sealing systems. We offer PTFE soft seals for temperatures from -40℃ to 200℃. We offer metal hard seals for high temperatures up to 400℃ and above. We also offer fire-safe designs that meet API 607 standards. The fire-safe seal keeps the valve shut even after a fire. Our high performance butterfly valve includes low-emission packing. This meets ISO 15848 for fugitive emissions. For oil and gas projects, we offer NACE-compliant materials. These resist sulfide stress cracking. We test every product on our own equipment. We check shell strength, seat tightness, and packing seal. Each valve must meet Class VI leakage standards. Our product is a dependable choice for critical applications.

This high performance butterfly valve serves many heavy industries. Oil and gas plants use it for pipeline collection and processing. Power plants use it for cooling water and boiler feed water bypass. Pulp and paper mills use it for stock and chemical lines. Chemical plants use it for corrosive and high-temperature fluids. Sizes range from DN80 to DN300. Pressure ratings are Class 150 and Class 300. You can choose handle, worm gear, pneumatic, electric, or hydraulic operation. Our product gives you the strength and sealing you need for severe service.
