D973H electric clip-seal butterfly valve

D973H electric clip-seal butterfly valve is widely used in petroleum, chemical, electric power, metallurgy, food, pharmaceutical, textile, paper and other industries, can be installed in temperatures ≤425 ℃, the medium is gas, air, steam, water, sea water, oil and other industrial pipe-line and off for regulating the flow medium.
Drive in the form of a manual, worm gear, pneumatic, hydraulic, electric, electro-hydraulic actuator linkage, enabling remote control and automation. Metal seal butterfly valve series, the Department of long life, energy-saving butterfly. Its structure using three-dimensional knitting heart principles of design, the use of hard and soft seat sealing compatible multi-level structure, processing skills, advanced technology. The product consists of the main components of the valve body, disc, multi-level seat, stem, transmission and other components. It is widely applied to the pipe metallurgy, electric power, petroleum, chemical, air, gas, flammable gas, and water supply and drainage and other corrosive media.
Product Features
Because this product uses a three-dimensional eccentric butterfly valve design principles, so that the sealing surface space trajectory to reach an idealized, no mutual friction between the seal faces, without interference, coupled with the sealing material is properly selected, so that the valve sealing, corrosion resistance , high temperature resistance and wear resistance has been a reliable guarantee. Its main features are as follows:
1, open the small moments, flexible and convenient, energy saving.
2, three-dimensional knitting heart structure, the disc more and more tightly shut, reliable sealing performance, achieved without leakage.
3, high pressure, corrosion resistance, wear resistance, and long life.
