Electric flanged butterfly valves are essential components used in a wide range of industrial applications where flow control is necessary. These valves are designed to regulate the flow of liquids, gases, and slurries in pipelines, providing an efficient and reliable solution for a variety of industries, including water treatment, oil and gas, HVAC, and chemical processing. In this article, we will explore the construction, working principle, advantages, applications, and maintenance of electric flanged butterfly valves, highlighting their significance in modern industrial systems.

    Construction of Electric Flanged Butterfly Valves

    An electric flanged butterfly valve consists of several key components: a valve body, a disc, a shaft, a seat, and an electric actuator. The valve body is typically made of materials such as cast iron, stainless steel, or other durable metals, depending on the specific requirements of the application. The disc, which is the primary element that controls the flow of fluid, is positioned in the center of the valve. When the valve is in the closed position, the disc completely obstructs the flow path, while in the open position, the disc is rotated to allow the flow to pass through.
