Description
The HAK Pneumatic 3500 Series Air Actuated Ball Valve features a robust stainless steel 3-piece body, designed for long-lasting 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 double-acting pneumatic actuator, the valve uses compressed air to both open and close, providing precise bi-directional control without relying on internal springs. This setup is ideal for systems that require consistent, powered actuation in both directions. The 3500 Series is available in both L-port and T-port flow configurations, offering flexible solutions for diverting, mixing, or isolating media based on application needs.
Compared to direct-acting valves, the 3500 Series delivers higher flow capacity, expanded pressure and temperature compatibility, and enhanced operational durability. Its reliable and efficient design makes it a trusted solution for industrial automation, chemical processing, and fluid handling systems where accurate flow routing is critical.
Construction/Specification
| Valve Type | 3-Way Ball Valve with Spring Return Actuator |
| Material: Body | 316 Stainless Steel / CF8M |
| Service Media | Air, Gas, Liquid, Water, Steam |
| Actuator Operating Pressure | 100 PSI Standard |
| Actuator Operating Pressure Range | 45 – 120 PSI |
| Seal Material | Teflon (PTFE) |
| Operating Pressure | 0 to 1000 PSI at 100 °F |

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.
