Pneumatic control valves are valves actuated by compressed air or gas to regulate fluid flow in a piping system. They are widely used in industrial automation processes due to their reliability, precision control, and ease of operation.

Features:

• Pneumatic Actuation: Uses compressed air or gas to open, close, or modulate the flow of fluid within the valve.
• Precise Flow Control: Pneumatic control valves offer precise control over flow rate or pressure, making them suitable for various automation applications.
• Remote Operation: Pneumatic valves can be controlled remotely using solenoid valves or pilot valves, enabling centralized control systems.
• Wide Range of Applications: Pneumatic control valves are used in various industries for process control applications involving liquids, gases, or slurries.
• Bellows Seal (Based on the Image): The image specifically shows a bellows pneumatic control valve, where the bellows most likely function as a seal or isolating element within the valve.
