DELCO Industrial Pneumatic Valve Actuator Series, High Torque, Compact Design, Anti-Corrosion for Ball/Butterfly Valve Control Systems
-
Flexible Operating Media: Uses dry/lubricated air or non-corrosive gases (≤30μm particles).
-
Wide Air Pressure: Operates from 2.5 Bar to 8 Bar air supply.
-
Broad Temperature Range: Functions from -35°C to +80°C (low temp) and -15°C to +50°C (high temp).
-
Standard Operation: Reliable performance within -20°C to +80°C.
-
Precise Adjustment: Allows ±5° travel adjustment at 0° and 90° rotation.
-
Industrial Durability: Built for robust industrial air-operated applications.
The DELCO AT Series Pneumatic Valve Actuator offers versatile solutions for valve control.
Single - Acting Model
Principle: It uses compressed air to drive valve opening or closing in one direction. When the air supply is interrupted, a built - in spring automatically resets the actuator to a pre - set safe position, like a fail - safe close or open.
Features & Advantages: Compact and energy - efficient, it ensures safety in case of air failure. It's ideal for industries where safety is crucial, such as petrochemicals, as it quickly triggers protection mechanisms in emergencies.
Double - Acting Model
Principle: Alternately supplying compressed air to two chambers on either side of the piston, it enables bidirectional movement for valve operation.
Features & Advantages: Characterized by fast action, stable output force, and high - frequency operation capability. It's perfect for applications demanding precise valve position control, like in power plants or large - scale water treatment facilities, where frequent and accurate valve adjustments are necessary.

Pneumatic Valve Actuator Accessories
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.
