DELCO Corrosion-resistant Fluorine lined Pneumatic Ball Valves
The corrosion-resistant fluorine-lined ball valve is designed to control the flow in pipelines with strong corrosive media. Featuring a flange type design, its cavity and ball are lined with corrosion-resistant polypropylene through high-pressure injection molding, ensuring excellent sealing and durability.
This valve is widely used in chemical, petroleum, metallurgy, and pharmaceutical industries, particularly for handling acids and alkalis. It is especially effective in water treatment processes, making it an ideal choice for anticorrosive valve applications.

Air source processor: Combines filtering, pressure reduction, and lubrication functions, ensuring stable outlet pressure. Available in two-piece assemblies for filtering compressed instrument air and three-piece configurations for added lubrication.
Pneumatic solenoid valve: Regulates the opening and closing of pneumatic valves by magnetizing and demagnetizing to direct gas flow based on voltage signals. Offers precise control over valve operations, commonly used for managing gas source and circuit flow.
Limit switch: Detects valve status and outputs signals for open or closed positions. Critical in automatic control systems, confirming and executing subsequent programs, providing valve interlock protection, and indicating remote alarms within the system.
Valve positioner: Crucial for precise control over valve positioning in pneumatic control valves, comparing valve stem displacement and controller output signals, adjusting the actuator output signal accordingly.
Manual device: Complements pneumatic actuator assemblies, facilitating manual or pneumatic operation for butterfly and ball valves with a 90° opening. Ensures versatility and flexibility in valve operation, allowing for manual and automated control as needed.
