What Is a Butterfly Valve?

A butterfly valve is a type of quarter-turn valve utilized in pipelines to control or block the flow of fluids. It functions by rotating a disc or vane, resembling the wings of a butterfly, within the valve body to manage the flow. These valves find widespread use across different industries owing to their straightforward design, adaptability, and cost-efficiency. They are particularly prevalent in water supply, distribution, and pumping stations, offering advantages such as lightweight construction, compactness, smaller installation footprint, and quicker actuation speeds compared to other valve types.

Why Use A Butterfly Valve?

Butterfly valves are lighter and smaller than other control valves. Therefore, for the regulation of pipeline flow, a butterfly valve is a better choice. The valve body of the butterfly valve is strong, which leads to the butterfly valve having a strong shock resistance. The connection mode of the butterfly valve can meet the requirements of different working conditions of different users.

What are butterfly valve parts?

Here are the main components of a typical butterfly valve:

  • Body: The body of the butterfly valve is the main outer casing that houses all the internal components. It provides connections for the inlet and outlet pipes.

  • Disc or Vane: The disc or vane is the central component of the butterfly valve that controls the flow of fluid. It is mounted on a shaft running through the center of the valve body.

  • Seat: The seat is a sealing surface within the valve body against which the disc makes contact when the valve is closed. It ensures a tight seal to prevent leakage when the valve is in the closed position.

  • Shaft: The shaft is the component that connects the disc to the actuator (such as a lever, handwheel, pneumatic actuator, or electric actuator). It transmits the rotational motion from the actuator to the disc, allowing it to open or close the valve.

  • Bearings: Bearings support the shaft within the valve body, allowing smooth rotation of the disc. They reduce friction and wear on the shaft and ensure proper alignment of the disc within the valve body.

  • Actuator: The actuator is the mechanism used to operate the butterfly valve. It can be manual, such as a lever or handwheel, or automated, such as a pneumatic or electric actuator.

  • Stem Seal: In some butterfly valve designs, a stem seal is used to prevent leakage around the shaft where it passes through the valve body.
