Three eccentric hard seal butterfly valve series products, is our company's development of long life, energy saving butterfly valve. The product conforms to the standard JB/T8527-97(metal seal butterfly valve), GB/T13927-92(general valve pressure test) standard and other valve related standards. This product is composed of valve body, butterfly plate, sealing ring, transmission mechanism and other main components. Its structure adopts the principle of three-dimensional eccentric design, elastic seal and hard and soft multi-layer seal compatible processing new technology, so that the butterfly valve in operation, reduce its torque force, to achieve the function of labor saving, energy saving. To ensure the overall corrosion resistance, high temperature resistance, anti - damage reliability.
Specification：
1. Unique structure, small and light, flexible operation, labor-saving, convenient;
2. Reliable sealing, can achieve gas seal without leakage;
3. Flow characteristics tend to linear adjustability is good;
4. Using three eccentric principle, so that the sealing surface nearly zero damage to prolong the service life of the valve;
. Wide range of applications. Such as: can be used in water, steam, oil, air, gas and other media.
6. Suitable for different temperature and pressure grade below 6.4mpa, corrosion resistant and other media pipeline.
