Pneumatic butterfly valves are widely used in various industrial applications due to their simple design, reliability, and efficiency in controlling the flow of fluids. Among the key players in the manufacturing and supply of these valves is CNHELI, a company known for its commitment to quality and innovation in valve technology. In this article, we will explore the concept of pneumatic butterfly valves, their components, working principles, advantages, and applications, while highlighting the contributions of CNHELI in this field.

    What is a Pneumatic Butterfly Valve?

    A pneumatic butterfly valve is a type of flow control device that utilizes a rotating disk to regulate the flow of liquids or gases. This valve operates using pneumatic actuators that provide the necessary force to open or close the valve by rotating the disk. The design of a butterfly valve comprises a tubular body, a disc, and an actuator, which are essential for its operation. The disk is mounted on a shaft that runs through the center of the valve body, allowing it to rotate 90 degrees to either fully open or fully close the flow path.
