DELCO Cast Iron Pneumatic Double Flange Butterfly Valves
Introducing the DELCO DK67-FB pneumatic butterfly valve, featuring a double-acting standard control mode with an optional single-acting configuration. This valve boasts a robust construction with a choice between cast iron or ductile iron bodies, and optional 304 or 316 stainless steel components. Designed to operate with an input air pressure range of 2.5 to 8 bar, it requires a minimum 2-inch flanged connection. The default seat material is NBR, with options for EPDM or PTFE seats to accommodate various applications including air, water, light oil, fuels, solvents, alcohol, and many acids.
DELCO offers a range of pneumatic actuator butterfly valves in wafer type, lugged type, and flanged configurations. Contact us for more information.

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.
