DELCO Stainless Steel 4 Way Pneumatic Actuator Threaded Ball Valves

The 4-way pneumatic actuator threaded ball valve is widely used in various pipeline systems such as water supply, petrochemical, metallurgy, mining, textile, energy, paper, food, and steel industries. It is designed to switch the flow direction of media and to separate or mix the media. Available in stainless steel and plastic materials, it offers multiple connection types including threaded, flange, tri clamp, and welding. The valve ensures good sealing performance, achieving a leak-free seal through the elastic deformation of polytetrafluoroethylene (PTFE).

    DELCO Pneumatic 4 Way Air Operated NPT Thread Ball Valve

    The pneumatic actuator valve is designed with a compact structure for quick opening and closing, providing a smooth flow channel and minimal fluid resistance. It is available with both spring return (single acting) and double acting actuators, operating with a quarter-turn rotation. Made from new, durable stainless steel material, this valve is suitable for various media, including water, oil, air, and gas.

    Technical Parameters of Valve Actuator

    Double actingAir to open, air to close, air supplier failure to keep the current position
    Single acting N/CAir to open, interrupt air to close, air failure to close
    Single acting N/OAir to close, interrupt air to open, air failure to open
    Optional accessoryReversing solenoid valve, limit switch box, air filter reducing valve, positioner, handle manual, lock up valve.

    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.
