High Performance Eccentric Butterfly Valve

High Performance Eccentric butterfly valve differ from traditional concentric butterfly valves in that the disc is offset from the centerline of the valve body. This unique design feature allows the disc to rotate without rubbing against the seat throughout the entire range of motion, thus reducing wear and tear, and improving overall operational efficiency. The disc of an eccentric butterfly valve rotates around an axis that is not aligned with the pipe bore, which ensures a more reliable seal when closed. As the disc approaches the fully closed position, it moves towards the seat at an angle, ensuring a linear contact that enhances sealing effectiveness and minimizes leakage rates.

Features

1. Robust Construction: High-performance eccentric butterfly valves are constructed with high-quality materials such as stainless steel, carbon steel, or special alloys to withstand harsh operating conditions, high pressures, and extreme temperatures.

2. Zero Leakage: The linear seating action ensures bubble-tight shut-off, which is especially critical in applications dealing with hazardous materials, high purity fluids, or those requiring minimal emissions.

3. Reduced Wear: The non-rubbing action between the disc and seat prolongs valve life, decreases maintenance requirements, and minimizes downtime.

4. Low Torque Operatio: The off-centered design significantly reduces the required torque to operate the china valve supplier, leading to lower actuator costs and energy consumption.

5. Triple Offset Design: High performance butterfly valve vs butterfly valve feature a triple offset design, where the disc is offset from both the shaft centerline and the seat axis.
