Industrial Actuated Butterfly Valves

Industrial actuated butterfly valves are valves used to control the flow of fluids in industrial processes. They consist of a circular disc or vane with its pivot axis at right angles to the direction of flow in the pipe, which rotates on a shaft to open or close the valve. Actuation refers to the method by which the valve is controlled, typically through an external power source such as pneumatic, hydraulic, or electric actuators.

Here’s a breakdown of the components and functions:

  1. Valve Body: Usually made of metal such as cast iron, ductile iron, stainless steel, or carbon steel. The body contains the disc and is designed to withstand high pressures and temperatures.

  2. Disc: The disc is the part of the valve that controls the flow. It rotates around the shaft to open or close the valve.

  3. Shaft: The shaft is the central component that supports the disc and allows it to rotate. It connects the disc to the actuator.

  4. Actuator: This is the mechanism that drives the movement of the valve. Actuators can be pneumatic, hydraulic, or electric, depending on the application and requirements of the process.

  5. Seals: Seals ensure that the valve maintains a tight shut-off when closed and prevent leakage when the valve is open.

  6. Positioners and Controls: In some applications, positioners and control systems are used to precisely control the position of the valve based on feedback from sensors.

These valves are commonly used in industries such as oil and gas, water treatment, chemical processing, and power generation, where precise control of fluid flow is crucial. They offer advantages such as quick operation, tight shut-off, and suitability for large-diameter applications. Additionally, their actuation mechanisms allow for automation and remote control, improving efficiency and safety in industrial processes.
