DELCO Stainless Steel 3 Way Pneumatic Flange Ball Valves

The DELCO DK66-TF pneumatic flange ball valves offers versatile port configurations, available in 2-way, 3-way, or 4-way setups. While the default standard is GB, it also accommodates ANSI and API 6D standards. The valve comes with a standard double-acting control mode, with an option for single-acting. Constructed from either 304 or 316 stainless steel, it operates within an input air pressure range of 2.5 to 8 bar.

Featuring a minimum 1/2 inch flanged connection and a default PTFE seat, the DK66-TF is resistant to nearly all fluids. This robust valve is designed to withstand higher operating pressures and temperatures, making it suitable for demanding applications.

    Actuator

    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.
