3PS Stainless Steel Pneumatic Thread Ball Valves
The DELCO pneumatic threaded ball valve features a double-acting standard control mode, with an option for single-acting. It is constructed with a 304 or 316 stainless steel body and operates with an input air pressure range of 2.5 to 8 bar. The valve includes a minimum 1/4 inch female thread connection and a default PTFE seat, providing resistance to almost all fluids. It is suitable for applications involving higher operating pressures and temperatures.
Model: DK66-3PS
Size Range: 1/4″ to 4″
Pressure Range: 1.0 to 1.6 MPa
Material: Stainless Steel 304, 316
3PS Series Pneumatic Actuator Thread Ball Valve
The valve is available with either a spring return (single acting) or double acting pneumatic actuator and can deliver high torque up to 4678Nm.

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.
