D673H Pneumatic Triple Eccentric Hard Seal Butterfly Valve Product Features

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

  1. Small opening torque, flexible and convenient, labor-saving and energy-saving.
  2. The three-dimensional braided core structure makes the butterfly plate tighter and tighter, and its sealing performance is reliable and leak-free.
  3. High pressure resistance, corrosion resistance, wear resistance, long service life, etc.
