DELCO Double Union UPVC 3 Way Pneumatic Ball Valves
The DELCO DK66-3PL Pneumatic PVC Ball Valves is available in 2-way or 3-way port configurations. It comes with a standard double-acting control mode, with a single-acting option available. Constructed from UPVC or PVC, with an optional CPVC body, this valve operates within an input air pressure range of 2.5 to 8 bar.
Featuring a minimum 1/2 inch union connection, it also offers an optional internal female thread. The default seat material is EPDM, making the valve suitable for common applications involving air, hot water, cold water, and low-pressure steam.
Model: DK66-3PL
Size Range: 1/2″-2″
Pressure Range: 1.0~1.6MPa
Material: PVC, CPVC, UPVC

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.
