Features of D643W triple eccentric hard seal pneumatic butterfly valve:

Because the butterfly valve of this product adopts the three-dimensional eccentric principle design, the space movement trajectory of the sealing surface is idealized, and there is no friction and interference between the sealing surfaces, and the sealing material is selected appropriately, so that the butterfly valve has a sealing performance and corrosion resistance. , 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 seal is leak-free.

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