Our metal-sealed butterfly valve stands as a testament to years of dedicated research and cutting-edge innovation. Developed and optimized by Onn Valve Co., Ltd.'s expert technical team, this product seamlessly incorporates advanced foreign technologies. Utilizing the principle of three-dimensional eccentricity, our valve boasts two structural forms: elastic and multi-level. The elastic metal-sealed butterfly valve features a butterfly plate and valve seat machined into spherical surfaces, which achieve a secure seal through deformation when closed. In the multi-level structure, two sealing surfaces contact each other, with the butterfly plate's sealing part formed by overlapping soft and hard sealing materials. Compression-induced deformation creates a robust sealing force. These structures allow the sealing pairs to separate instantly upon opening, reducing friction and significantly extending the valve's lifespan. In essence, our metal-sealed butterfly valves offer the following exceptional advantages:
1. Unique and compact design ensures effortless operation with easy opening and closing.
2. Guarantees reliable and airtight sealing, eliminating any leakage.
3. Exhibits flow characteristics that facilitate proportional adjustment, ensuring optimal performance.
4. Employs the principle of three eccentricities, resulting in negligible wear on the sealing surface and an extended service life.
5. Versatile application range, suitable for media such as water, steam, oil, air, gas, and more.
6. Applicable to various medium pipelines at different temperatures and pressures up to 4.0MPa.
7. Specifically designed to perform exceptionally well in high-temperature conditions.
Our triple eccentric metal-sealed butterfly valves represent the pinnacle of modern butterfly valve technology. They are the ultimate solution for regulating flow and cutting off or connecting fluids.
