Double Eccentric Butterfly Valve
Structural features:The axis of the valve stem deviates from both the center of the butterfly disc and the center of the body.
The effect of double eccentricity enables the butterfly disc to quickly detach from the valve seat after the valve is opened, greatly eliminating unnecessary excessive squeezing and scraping between the butterfly disc and the valve seat, reducing the opening resistance distance, reducing wear, and improving the valve seat life. Double eccentric butterfly valves are mainly used for water drainage in water plants, power plants, steel smelting, chemical industry, water source engineering, environmental facility construction, etc.
Advantages:
1. Reasonable design, compact structure, easy assembly and disassembly, and convenient maintenance.
2. The eccentric structure is used to reduce the friction of the sealing ring and prolong the service life of the valve.
3. Completely sealed with zero leakage. Can be used in ultra-high vacuum conditions.
4. Replacement of valve disc sealing ring, butterfly disc, shaft and other materials can be applied to a variety of media and different temperatures.
Standard:
1.Design and manufacture as per BS EN593
2.Face to face dimensions as per BS EN558 Series 13/14
3.Flange dimensions as per BS EN1092-2
4.Pressure test as per BS EN12266-1
