Double Eccentric DN100 - DN2000 1.6 MPa Flanged Butterfly Valve




Detailed Product Description
 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.
 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.
