A butterfly valve in irrigation system is used for isolating or regulating flow of water. The working principle of butterfly valves is similar to that of ball valves, allowing for quick shut off. Butterfly valves are very popular because they are cheaper as well as light in weight, requiring less support and maintenance. The Butterfly disc is located at the center of the pipe; a rod passes through the disc and is connected to an actuator on the outside of the valve. Turning the actuator turns the disc either parallel or perpendicular to the water flow. In contrast to ball valve, the disc is always there within the water flow, so there is always a pressure drop in the pipe, irrespective of valve position.
Irrigation and landscaping flanged butterfly valve are quarter-turn valves. While being operated, these valves are either fully open or closed when the disc is rotated a quarter turn. Flanged butterfly valves have a metal disc mounted on a rod. When the valve is shut off, the disc is rotated so that it totally blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it lets the water in the pipeline pass without restriction.
