Three eccentric hard seal butterfly valve

Product structure and performance: three eccentric hard seal butterfly valve series products, the Department of our company developed a long life, energy-saving butterfly valve. The product conforms to the national standard JB/T8527 (metal seal butterfly valve),GB/T13927 (general valve pressure test) and other relevant standards of the valve. This product consists of valve body, butterfly plate, sealing ring, transmission mechanism and other major components. Its structure is designed with three-dimensional eccentric principle. Elastic seal and hard and soft multi-layer seal compatible processing new technology, so that the butterfly valve in the operation of the work, reduce its torque force, to save effort, energy saving function. So as to ensure the overall corrosion resistance, high temperature resistance, wear resistance reliability.

 

 

 

Brief introduction of product structure and performance

Three eccentric hard seal butterfly valve series products, the Department of our company developed a long life, energy-saving butterfly valve. The product conforms to the national standard JB/T8527 (metal seal butterfly valve),GB/T13927 (general valve pressure test) and other relevant standards of the valve.

This product consists of valve body, butterfly plate, sealing ring, transmission mechanism and other major components. Its structure is designed with three-dimensional eccentric principle. Elastic seal and hard and soft multi-layer seal compatible processing new technology, so that the butterfly valve in the operation of the work, reduce its torque force, to save effort, energy saving function. So as to ensure the overall corrosion resistance, high temperature resistance, wear resistance reliability. Its main performance characteristics are:

1. Unique structure, small and light, flexible operation, labor saving and convenient.

2. The seal is reliable, and the air seal can be achieved without leakage.

3. The flow characteristics tend to be the best in linear regulation.

4. Using three eccentric principle, the sealing surface is approximately zero wear to extend 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. Applicable to different temperature and pressure grade below 6.4MPa, corrosion resistance and other media pipeline.
