The disc is the central component of the butterfly valve. It is typically a flat, circular or oval-shaped plate that is mounted on a spindle or shaft. When the valve is open, the disc is parallel to the flow of the fluid, allowing for unobstructed flow. When the valve is closed, the disc is turned perpendicular to the flow, blocking the passage of fluid. The body of a butterfly valve is a casing or housing that contains the disc and provides a path for the fluid to flow through when the valve is open. Butterfly valve bodies come in various shapes and configurations, such as wafer-style, lug-style, and flanged-style, depending on the specific application and installation requirements. To control the position of the disc (open or closed), butterfly valves are equipped with an actuator. Actuators can be manual (hand-operated), pneumatic, electric , or hydraulic. The choice of actuator depends on the valve’s size, application, and the level of automation required. The seat is a sealing surface located around the perimeter of the valve’s body, against which the disc makes contact when the valve is closed. The seat provides a tight seal to prevent leakage when the valve is in the closed position. The stem is the shaft that connects the actuator to the disc. When the actuator is activated, it rotates the stem, which in turn rotates the disc to control the flow of fluid.
