Product Details
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.
