  • Product Introduction
  • Service Promise
  • Ordering Process

D643H pneumatic flange hard-sealed butterfly valve is widely used in petroleum, chemical, electric power, metallurgy, food, medicine, textile, paper and other industries. It can be installed in the temperature (< 425%) medium for gas, air, steam, water, sea water, oil and other industrial pipe network for regulating flow and cutting off the medium.


Drive forms include manual, worm gear drive, pneumatic, hydraulic, electric, electro-hydraulic linkage and other actuators, which can realize long-distance control and automatic operation. Metal hard seal butterfly valves series products are long life and energy saving butterfly valves. Its structure adopts three-dimensional core design principle, and the valve seat adopts a multi-level structure compatible with hard and soft seals, with exquisite machining and advanced technology. This product is made up of main parts such as valve body, butterfly plate, multi-layer valve seat, valve stem, transmission mechanism and so on. Therefore, it is widely used in metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas, water supply and drainage pipelines and other corrosive media.


Product features


The pneumatic flange hard-sealed butterfly valve is designed on the principle of three-dimensional eccentricity, which makes the space trajectory of the sealing surface ideal. There is no friction between the sealing surfaces, no interference, and the sealing material is properly selected. Thus the sealing, corrosion resistance, high temperature resistance and wear resistance of the butterfly valve are reliably guaranteed. Its main characteristics are as follows:


1, opening torque is small, flexible and convenient, labor-saving and energy saving.


2, three dimensional heart structure, so that the butterfly plate closer and closer, its sealing performance is reliable, to achieve no leakage.


3, high pressure, corrosion resistance, wear resistance, long service life and so on.
