WebMay 14, 2024 · A valve controls system or process fluid flow and pressure by performing any of the following functions: Stopping and starting fluid flow. Varying (throttling) the amount of fluid flow. Controlling the direction of fluid flow. Regulating downstream system or process pressure. Relieving component or piping over pressure. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they cost less than other valve designs, and are lighter weight so they need less support. The disc is positioned in the center of the pipe. A rod passes through the disc to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, so it indu…
