The metal sealed butterfly valve, perfected by Onn Valve Co., Ltd.'s team of experts, represents the pinnacle of innovation after extensive research and leveraging cutting-edge foreign technology. Utilizing the principle of three-dimensional eccentricity, it comes in two structural variants: elastic and multi-level. The elastic metal sealed butterfly valve features a butterfly plate and valve seat meticulously machined into spherical surfaces, achieving a seal through the spherical deformation upon closure. In the multi-level structure, the sealing surfaces make contact, with the butterfly plate's sealing area formed by overlapping soft and hard sealing materials, creating a sealing force through compression deformation. Both designs ensure the sealing pairs separate instantly upon opening, minimizing friction and significantly extending valve longevity. In essence, metal sealed butterfly valves offer the following exceptional advantages:
1. Innovative and compact design, facilitating effortless operation and ease of use.
2. Unmatched sealing integrity, delivering airtight performance without any leakage.
3. Flow characteristics are precisely adjustable, guaranteeing optimal performance.
4. Employing the principle of triple eccentricity, the sealing surface experiences negligible wear, ensuring an extended lifespan.
5. Versatile application range, suitable for media such as water, steam, oil, air, and gas.
6. Ideal for various medium pipelines across different temperatures and pressures up to 4.0MPa.
7. Exceptionally suited for high-temperature conditions.
Triple eccentric metal sealed butterfly valves represent the forefront of butterfly valve technology, making them the premier choice for flow regulation and the control of fluid dynamics.
