DELCO Stainless Steel Pneumatic 3 Way Thread Ball Valves
The DELCO pneumatic ball valve is available in L port or T port configurations and features a double-acting standard control mode, with a single-acting option also available. It is constructed from 304 or 316 stainless steel and operates with an input air pressure of 2.5 to 8 bar. The valve has a minimum 1/4 inch female thread connection and comes with a default PTFE seat, providing resistance to almost all fluids. It is suitable for applications involving higher operating pressures and temperatures.
Model: DK66-3T
Size Range: 1/4″ to 4″
Pressure Range: 1.0 to 1.6 MPa
Material: Stainless Steel 304/316
DELCO Pneumatic 3 Way Thread Ball Valve
The valve features a long service life, eco-friendliness, and easy installation. It is available with spring return (single acting) and double acting actuators. You can choose between 2-way air actuator ball valves or 3-way air actuator ball valves in T type and L type configurations. Operating with a quarter-turn rotation, the valve is constructed from stainless steel and plastic materials. Connection types include threaded, flange, tri clamp, and welding, making it versatile for various applications. It is suitable for a wide range of media, including water, oil, air, and gas.

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.
