Product introduction
The soft seated eccentric flanged butterfly valve ,newly developed by company ,can be used for water supply and drainage systems in
water works ,power generating factory ,mill plant ,paper-making ,chemicals and water source projects and the construction of
environment installations ,especially suitable for use as an ideal equipment for throttling or shutting off flow in water pipelines .
Structure traits
1. Reasonable in design, compact in construction ,easy to install and maintain .
2. The double eccentric structure reduces friction of the sealing ring, providing the valve a long service life .
3. "T" structure of the disc sealing ring .The sealing pair is linear sealing .
4. Bubble-tight sealing with no leakage under testing pressure .
• Replacing materials of the disc ring ,"O"-ring ,disc and shaft ,the valve can be used for various medium and temperature .
