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. When this rod rotates the disk by 90° the butterfly valve opens or closes.

Butterfly valve with actuator electric valve - An electrically actuated butterfly valve is a quarter-turn valve controlled by an electric motor. It offers fast and precise flow regulation, remote operation, and versatility for various applications.

Butterfly valves play an important role in water supply. Learn more about their types, actuation methods and advantages in particular applications.

The main function of the butterfly valve is to close, open, or slow the fluid flow. It uses to control the fluid flow in either direction.

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 work on a simple quarter-turn operation through a disc. Different butterfly valve parts function together to achieve the results. The process occurs at 90 degrees and acts perpendicular to the flow when closed, completely blocking the fluid flow.

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.”

2022年7月29日 · While throttling valves, most butterfly valves function as only block valves. They are functional for various media, and due to their lightweight and low cost, they are found in several modulation devices. The main components of a …

2024年8月24日 · Butterfly valves are a type of quarter-turn valve designed to regulate or isolate the flow of a fluid. They are named ‘butterfly’ because of a disc that rotates like a butterfly’s wings – with the stem as its body. The control mechanism in a butterfly valve is a …
