A pneumatic control valve is a type of control valve that uses compressed air as the actuating medium to control the flow of fluids (typically gases or liquids) within a system. The valve adjusts the flow rate by changing the size of the flow passage, responding to signals from a controller or process system. Pneumatic control valves are often used in applications requiring precise flow control, reliability, and safety.

A pneumatic butterfly valve is a type of actuated butterfly valve that utilizes compressed air to open or close the valve disc, allowing or blocking media flow in a pipeline. Unlike manual valves that require physical intervention, pneumatic valves enable remote or automated control, making them ideal for high-speed and high-cycle applications in industries such as water treatment, chemical processing, and HVAC.

A pneumatic ball valve is a type of valve that uses compressed air to operate a stainless steel ball inside the valve body, allowing or blocking the flow of fluids such as water, oil, or gas. This valve is often used in industrial systems where fast, reliable, and automated open and close actions are required.
