  • Product Description
  • Detailed parameters
  • Pneumatic flange type hard seal butterfly valve series products, Department of long-life, energy-saving butterfly valve. Its structure adopts the principle of three-dimensional core design, the valve seat adopts the multi-level structure of hard and soft seal compatibility, exquisite processing, advanced technology. This product consists of valve body, butterfly plate, multi-level valve seat, valve stem, transmission mechanism and other major components.

    Pneumatic flanged butterfly valve

    Because the butterfly valve of this product adopts the three-dimensional eccentric principle design, the space motion trajectory of the sealing surface is idealized, and there is no friction and interference between the sealing surfaces, and the sealing material is properly selected, so that the sealing performance and corrosion resistance of the butterfly valve, High temperature resistance and wear resistance have been reliably guaranteed. Its main features are as follows:

    1. The opening torque is small, flexible and convenient, labor-saving and energy-saving.

    2. The three-dimensional core structure makes the butterfly plate tighter and tighter, and its sealing performance is reliable and there is no leakage.

    3. High pressure resistance, corrosion resistance, wear resistance, long service life, etc.
