What is High Performance Butterfly Valve
High-performance butterfly valves are industrial valves that overcome the sealing and pressure limitations of traditional butterfly valves. Their design integrates double/triple eccentric structures, high-performance sealing materials, and precision machining technology, offering the following core advantages:
High Sealing Performance
The triple eccentric structure achieves "wedge effect compression" on sealing surfaces during closure through angle eccentricity design, meeting ANSI Class VI zero-leakage standards (leakage rate as low as 10⁻⁶ cc/sec), far exceeding traditional butterfly valves.
Soft sealing (e.g., fluororubber, PTFE) is suitable for low-temperature applications, while hard sealing (metal-to-metal or hard alloy) withstands 600°C high temperatures and highly corrosive media.
High Pressure Resistance & Long Service Life
Capable of withstanding pressure ratings from Class 150 to Class 2500 (PN16 to PN420), suitable for supercritical fluid and high-pressure gas pipelines.
Hard-sealed valves offer a lifespan of over 100,000 cycles, while soft-sealed valves provide approximately 50,000 cycles, with low maintenance costs.
Low Friction & Energy Efficiency
Eccentric design reduces sealing surface friction during operation, lowering torque by over 50%. With minimal flow resistance, the rated flow coefficient is about 3 times that of same-sized single-seat valves, ideal for high-flow applications.
Material Adaptability
Body materials include carbon steel, stainless steel, alloy steel, and corrosion-resistant alloys (e.g., Hastelloy C-276), resistant to acidic, alkaline, and saline corrosive media. Suitable for harsh environments such as chemical plants and marine engineering.
