What is true about high-performance butterfly valves?

High-performance butterfly valves are designed with specific features that enhance their functionality in demanding applications. The eccentric shaft mount is one of the key aspects that sets these valves apart. This design allows for a more efficient sealing capability by positioning the disc off-center relative to the valve body. As the valve opens, the disc moves away from the seat, which minimizes friction and wear on the sealing surface, leading to lower torque requirements during operation. This design contributes to increased reliability and longevity, making these valves suitable for high-performance applications.

The eccentric design also helps manage the flow dynamics within the valve, reducing turbulence and pressure drop, which can improve the overall efficiency of the system. This ability to function efficiently and with reduced wear under varying operating conditions is what makes the eccentric shaft mount a significant feature of high-performance butterfly valves.
