DELCO Valve Pneumatic Actuator Cast Iron Wafer Butterfly Valves
The pneumatic wafer-type butterfly valve is available with a double-acting standard control mode, with a single-acting option also available. It features a body made from either cast iron or ductile iron, with optional 304 or 316 stainless steel. The valve operates with an input air pressure range of 2.5 to 8 bar and has a minimum connection size of 2 inches. It comes with a default NBR seat, but EPDM, PTFE, and VITON seats are also available. This valve is suitable for handling air, water, light oil, fuels, solvents, alcohol, acids, and more.

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.
