Description
The HAK Pneumatic 3500 Series Air Actuated Ball Valve features a robust stainless steel 3-piece body, designed for reliable performance and easy maintenance with a slide-out center section. This three-way pneumatic actuated ball valve is ideal for automated flow control of air, gas, water, steam, and other industrial fluids in demanding environments.
Configured with a single-acting (spring-return) pneumatic actuator, the valve opens using compressed air and automatically returns to its default position when air is removed, ensuring fail-safe operation. The 3500 Series is available in both L-port and T-port flow configurations, offering flexible solutions for diverting, mixing, or separating media depending on system requirements.
Compared to direct-acting valves, the 3500 Series provides higher flow capacity, broader pressure and temperature compatibility, and enhanced durability. Its design makes it an excellent choice for industrial automation, chemical processing, and hazardous environments where consistent and secure flow control is essential.

HAK Pneumatic 3500 Series Air Actuator – NAMUR Valve & Visual Indicator Compatible
The HAK Pneumatic 3500 Series air actuator is designed for direct integration with both 5-way NAMUR solenoid valves OR 5-way NAMUR air pilot valves, allowing seamless control without the need for additional mounting hardware.
Additionally 3500 Series actuator supports the installation of a Visual Position Indicator, providing a clear and immediate visual reference of valve open/closed status. This feature enhances operational safety and monitoring, especially in industrial automation and process control environments.
Together, the NAMUR-compatible valve interface and Visual indicator options make the 3000 Series actuator a versatile and high-performance solution for automated valve systems.
