A butterfly valve is a valve that isolates or regulates the flow of a fluid. The closing mechanism is a disk that rotates. Principle of operation. Operation is similar to that of a ball valve, which allows for quick shut off.
Butterfly valves play an important role in water supply. Learn more about their types, actuation methods and advantages in particular applications.
Butterfly valves belong to the quarter-turn rotational motion valves family and are used primarily to stop, regulate, or start the flow. The term “butterfly” in a butterfly valve is actually a disk that is connected to a rod.
A butterfly valve is a quarter-turn valve used to open, close, and regulate fluid flow. It has an easy operation. The 90-degree rotation of the valve handwheel or actuator fully opens or closes the fluid flow.
Butterfly valves are quarter-turn rotational motion valves that can start, stop, and regulate flow. They are simple to use, which makes them a popular choice. Below are the parts of a butterfly valve and how they contribute to the function of the valve.
Butterfly valves are quarter-turn rotary motion valves used as throttling valves to control flow through a system. They can be used with many different media. Butterfly valves offer several advantages including quarter-turn, openness for less plugging, and good control capabilities.
According to the British Valve and Actuator Association, a butterfly valve is “a valve in which the obturator rotates about an axis at right angles to the direction of flow, and in the open position, flow passes around the obturator.”
