Product structure and performance of D643H pneumatic butterfly valve :
Hard-sealed butterfly valve series are long-life, energy-saving butterfly valves developed by our company in 1996. Products comply with national standards JB / T8527-97 (metal sealed butterfly valve), GB / T13927-92 (general valve pressure test) standards and other relevant standards of the valve. This product consists of valve body, butterfly plate, seal ring, transmission mechanism and other main components. Its structure adopts the three-dimensional eccentric principle design, and the new process compatible with elastic seal and hard-soft multi-layer seal enables the butterfly valve to reduce its torque force during operation and achieve the functions of saving energy and energy. So as to ensure the overall corrosion resistance. High temperature resistance. Reliability against wear and tear.
Second, D643H pneumatic butterfly valve features:
1. Unique structure, small and light, flexible operation, labor saving and convenient;
2. Reliable sealing, can achieve hermetic seal without leakage;
3. The flow characteristics tend to have the best linear adjustment;
4. Adopting the principle of triple eccentricity, so that the sealing surface is near zero wear and tear and prolong the service life of the valve
5. Wide range of applications. Such as: can be used for water, steam, oil, air, gas and other media.
6. It is suitable for various medium pipelines with different temperatures and pressure levels below 6.4MPa.
Third, D643H pneumatic butterfly valve uses:
Pneumatic butterfly valve is suitable for food. medicine. Petrochemical. Power plant. Steel Works. Industrial environmental water treatment and high-rise buildings. The best device for regulating the flow and cutting off the fluid is on the water supply and drainage pipeline.
