D343H, D343Y- -PN6~PN40- double eccentric PTFE sealing butterfly valve

Double eccentric butterfly valve is also called high performance butterfly valve, mainly applicable to water plants, power plants, steel smelting, chemical industry, water source engineering and environmental infrastructure construction system for drainage, especially suitable for use as a water pipeline, regulation and closure device. Compared with the midline butterfly valve, double eccentric butterfly valve is more resistant to high pressure, longer life, good stability.

Double eccentric butterfly valve is also called high performance butterfly valve, mainly applicable to water plants, power plants, steel smelting, chemical industry, water source engineering and environmental infrastructure construction system for drainage, especially suitable for use as a water pipeline, regulation and closure device. Compared with the midline butterfly valve, double eccentric butterfly valve is more resistant to high pressure, longer life, good stability. Compared with other valves, the greater the diameter of the lighter material, lower cost. However, due to the middle of the butterfly plate, flow resistance, so less than DN200 of the butterfly is not significant

Double eccentric butterfly valve in a single eccentric butterfly valve on the basis of further improvement. The structure is characterized in that the stem axis deviates from the center of the butterfly plate, and also deviates from the center of the body. The effect of the double eccentric valve can be opened immediately after the disc from the valve seat, substantially eliminating the unnecessary disc and valve seat over squeezing, scratching phenomenon, reduce the resistance from the open, reducing the wear and improve seat life. Scraping greatly reduced, but also makes the double eccentric butterfly valve can also be used to improve the application of butterfly valve in the field of high temperature.

1 reasonable design, compact structure, easy assembly and disassembly, easy maintenance.

2 adopt eccentric structure, reduce the friction of the sealing ring, prolong the service life of the valve.

3 completely sealed, leakage is zero. Can be used for ultra high vacuum conditions

4 replace the valve plate sealing ring, butterfly plate, shaft and other materials, can be applied to a variety of media and different temperatures
