Product Description
The metal sealed butterfly valve is developed and optimized by our company's technical personnel after years of research and development, combined with advanced technology of foreign butterfly valves. Adopting the principle of three-dimensional eccentricity, there are two structural forms: elastic and multi-level. The butterfly plate and valve seat of the elastic metal sealed butterfly valve are machined into spherical surfaces, which are sealed by the deformation of the spherical surface caused by the force when closed. The two sealing surfaces of the multi-level structure are in contact with each other, and the sealing part of the butterfly plate is formed by overlapping and pressing two sealing materials, soft and hard, relying on the deformation of the sealing pair during compression to form a sealing force. The two structures can instantly separate the two sealing pairs when opened, resulting in minimal friction and prolonging the service life of the valve. In summary, metal sealed butterfly valves have the following advantages:
1. Unique and compact structure, easy to open and close, and easy to operate.
2. Reliable sealing, achieving airtight sealing without leakage.
3. The flow characteristics tend to be adjusted proportionally, resulting in the best performance.
4. Adopting the principle of three eccentricities, the sealing surface is approximately zero wear and has a long service life.
5. Wide application range. For example, it can be used in media such as water, steam, oil, air, gas, etc.
6. Suitable for various medium pipelines at different temperatures and below 4.0MPa.
7. Especially suitable for high temperature situations.
Triple eccentric metal sealed butterfly valves are the development direction of butterfly valves today, and are the best devices for regulating flow and cutting off or connecting fluids.
