The butterfly valve of this product is designed based on the three-dimensional eccentric principle, which idealizes the spatial movement trajectory of the sealing surface. There is no friction or interference between the sealing surfaces. Coupled with the proper selection of sealing materials, the sealing of the butterfly valve is achieved
The performance, corrosion resistance, high-temperature resistance and wear resistance have been reliably guaranteed. Its main features are as follows:
It has a small opening torque, is flexible and convenient, and saves effort and energy.
2. The three-dimensional core-woven structure makes the butterfly plate tighter and tighter as it closes, ensuring reliable sealing performance and achieving no leakage.
3. High pressure resistance, corrosion resistance, wear resistance, and long service life, etc.

The D973H all-copper hard-sealed butterfly valve is widely used in industries such as petroleum, chemical engineering, power, metallurgy, food, medicine, light textile, and papermaking. It can be installed in environments with temperatures ≤425℃ and media including gas, air, steam, water, and seawater.
It is used for regulating flow and cutting off media in industrial pipeline networks such as oil products.
The drive forms include manual, worm gear transmission, pneumatic, hydraulic, electric, electro-hydraulic linkage and other actuators, which can achieve remote control and automated operation. The metal hard-sealed butterfly valve series products are long-life and energy-saving butterfly valves. its
The structure is designed based on the three-dimensional core-weaving principle. The valve seat adopts a multi-level structure compatible with both hard and soft seals, featuring exquisite processing and advanced technology. This product is composed of main components such as the valve body, butterfly plate, multi-layer valve seat, valve stem and transmission mechanism.
Therefore, it is widely applied to pipelines carrying corrosive media such as metallurgy, power, petroleum, chemical industry, air, gas, combustible gas and water supply and drainage.
