Modulating Butterfly Control Valve

Modulating butterfly control valves are versatile in their ability to isolate or regulate fluid flow within various industrial applications. At the heart of these valves is a centrally positioned disc that functions as the closing mechanism. This disc is connected to a handle or actuator through a shaft extending from the disc through the top of the valve body, enabling precise control over flow rates.

Unlike ball valves, where the ball completely obstructs or allows flow, the disc of a butterfly valve always remains within the flow path. This continuous presence of the disc can induce a slight pressure drop across the valve, depending on its position and the characteristics of the fluid being controlled. Despite this characteristic, butterfly valves are favored for their reliability, ease of operation, and suitability for large-scale flow control applications in various industries.
