Detailed Product Description
 
Double Eccentric 1.6MPa Flanged Butterfly Valve With Resilient Seat Conform to BS5155
 
Product Introduction:
The Rubber-seat Double eccentric Flange Butterfly valve,can be used for water supply and draniage systems in the industries of problem processing,chemicals,water works,Power generating factory,mill plant,paper-making and water source projects,especially suitable for use as anideal equipment for throttling or shutting off flow in water pipelines.
 
Features:
1. 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. Bubble-tight sealing with no leakage under testing pressure.
4. Replacing materials of the disc sealing ring,”O”ring,and disc,the valve can be used for various medium and tempreture.
