UAE Valve is recognized for its superior Double Eccentric Butterfly Valve Supplier in UAE. This valve is one of the configurations used to affect the flow of the liquid through its distinct disc and stem. The term “double eccentric” is in relation to the two areas that have an offset in the geometry, which gives more efficiency and durability than an ordinary butterfly valve.
Working Mechanism
The disc in its axial closure compresses against the sealing surface so that there is no leak. At first look, it seems that for disc valves operated this way, there will always be high torsional friction—the disc-ending is dragged by the fluid into the sealed position. This makes it relatively easier to open the valve and requires less twisting force from the operator. When in the fully open position, the entire disc is brought into alignment, ensuring no obstruction to fluid flow.
Key Design Features
- First Offset: The valve shaft (or stem) is recessed behind the centerline of the valve seat. This arrangement helps minimize contact between the disc and the seat whenever the valve is turned from the closed to the open position and vice versa.
- Second Offset: The disc itself is positioned at an offset from the centerline of the valve body. This cam movement minimizes contact between the disc and the seat, reducing wear during operation.
Advantages
- Reduced Wear and Tear: The offset design reduces contact between the disc and seat, minimizing friction and extending the valve's lifespan.
- Tight Seal: Provides a positive shut-off and leak-proof closure, making it ideal for applications requiring no leaks.
- Lower Operating Torque: Requires less force to open and close the valve, reducing the cost of actuation.
- Versatility: Suitable for high-pressure and high-temperature applications, widely used in water treatment, oil and gas, and chemical industries.
Applications
The double eccentric butterfly valve is suitable for industries requiring reliable flow control, particularly in the water industry, HVAC, and power industries where strength and sealing are critical.
