DELCO 2 Way Stainless Steel Pneumatic Flange Ball Valves
The DELCO pneumatic flange ball valve is available in 2-way, 3-way, or 4-way port configurations, with a default GB standard and optional ANSI or API 6D standards. It features a double-acting standard control mode, with a single-acting option available. Constructed from 304 or 316 stainless steel, it operates with an input air pressure of 2.5 to 8 bar and has a minimum 1/2 inch flanged connection. The valve comes with a default PTFE seat, making it resistant to almost all fluids and suitable for applications with higher operating pressures and temperatures.
Model: DK66-2PF
Size Range: 1/2″ to 8″
Pressure Range: 1.0 to 6.4MPa
Material:Stainless Steel 304/316, WCB

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.
