First, D643H hard seal pneumatic flange type butterfly valve overview:

The flanged hard-sealed pneumatic butterfly valve is designed with three-dimensional knitting principle. The valve seat adopts multi-layer structure compatible with hard and soft seal, and the technology is advanced. This product consists of valve body, butterfly plate, multi-level valve seat, valve stem, transmission mechanism and other main components. Therefore, it is widely used in pipelines of corrosive media such as metallurgy, electric power, petroleum, chemical, air, gas, combustible gas, and water supply and drainage.

Second, the main features of the hard seal pneumatic flange type butterfly valve:

1. The design adopts the principle of three eccentricity, the sealing is separated, the contact is closed, and the sealing performance is reliable;

2. The sealing ring is made of stainless steel. Under high temperature and cold conditions, the seal has no stress deformation, and has the characteristics of high temperature resistance, corrosion resistance and long service life.

3. The axial positioning device solves the problem of wear and leakage of the axial sealing surface, and the transmission device can be installed in any direction;

4. The flow area is large, the flow resistance coefficient is small, and the circulation capacity is strong;

5, anti-aging, anti-radiation, durable;

6, the seal can be adjusted, 100,000 life without leakage.
