Pneumatic butterfly valves are essential components in various industrial applications, renowned for their ability to control the flow of liquids and gases efficiently. This valve type comprises a circular disc or vane mounted on a rotating shaft, offering rapid opening or closing, which is crucial in processes requiring precise flow regulation. Among the leading manufacturers in this field is CNHELI, known for its commitment to delivering high-quality pneumatic butterfly valves that cater to diverse industry needs.

    The working mechanism of a pneumatic butterfly valve involves using compressed air to actuate the valve. When compressed air is supplied to the actuator, the valve disc rotates around its axis, allowing fluid to pass through or sealing it off completely. This rotational movement is typically 90 degrees, enabling quick and efficient operation. One of the significant advantages of pneumatic butterfly valves is their lightweight design compared to traditional valve types, which makes them easier to install and operate in various systems.

    Pneumatic butterfly valves are widely used across various sectors, including water treatment, chemical processing, oil and gas, and food and beverage industries. Their versatility makes them suitable for applications ranging from simple on/off control to more complex flow regulation systems. The ability to handle large volumes of flow efficiently while maintaining low-pressure drops is a key feature that sets pneumatic butterfly valves apart from their counterparts.
