Structural Characteristics and Applications

The hard-sealed high-temperature butterfly valve adopts a multi-layer metal hard-sealed structure (soft-hard laminated metal sheet), which combines the dual advantages of metal hard sealing and soft sealing. It exhibits excellent sealing performance under both room temperature and high-temperature conditions. Additionally, its unique tri-eccentric design ensures a tighter seal as the valve closes, providing automatic compensation for sealing. The oblique plate design allows for quick opening and closing, low flow loss, and flexible, convenient, and reliable operation.

This type of butterfly valve is widely used in industries such as metallurgy, building materials, chemicals, power stations, and papermaking, especially in applications requiring bi-directional sealing. Its design is based on the three-dimensional eccentric principle, which optimizes the spatial movement trajectory of the sealing surface, eliminating friction and interference between sealing pairs. Moreover, through carefully selected sealing materials, the butterfly valve ensures reliable sealing, corrosion resistance, high-temperature resistance, and wear resistance.

Product Features

  1. Small opening torque for flexible and convenient operation, saving energy.
  2. Tri-eccentric structure ensures a tighter seal as the valve closes, achieving leak-free performance.
  3. Resistant to high pressure, corrosion, and wear, ensuring a long service life.
  4. Utilizes an elastic stainless steel sealing ring installed on the valve body to achieve true zero leakage.
  5. Adjustable sealing, maintaining leak-free performance after 100,000 life cycles.
  6. Special sealing structure ensures excellent sealing performance under both high-temperature and room-temperature conditions, without stress deformation.
  7. Axial positioning device solves the problem of leakage caused by wear of the axial sealing surface, allowing the transmission actuator to be installed in any direction.
  8. Suitable for applications in clean pipelines in the food, pharmaceutical, chemical industries, as well as industrial environmental protection, water treatment, high-rise buildings, water supply and drainage pipelines, for opening, closing, or regulating media flow.
