    Automation Simplified

    The AOX-MZ Multi-Turn Electric Actuator is a premium industrial actuator designed for the precise automation of multi-turn valves, including gate valves, globe valves, and other rising stem valve applications. Engineered for demanding operating environments, the AOX-MZ combines high torque output, intelligent control capabilities, and robust construction to deliver reliable valve operation across critical industries such as water treatment, mining, oil and gas, power generation, chemical processing, and manufacturing. The actuator is designed to operate valves requiring multiple revolutions (360° rotation) and can also be configured with additional mechanical components to automate butterfly valves, ball valves, dampers, plug valves, louvre valves, and other specialised valve types.

    Built for Demanding Industrial Applications

    The AOX-MZ is equipped with specially designed high-starting-torque motors that ensure reliable valve operation, even from fully closed positions. It is available with three-phase AC, single-phase AC, and DC motor options to suit a wide range of industrial installations and operating requirements.

    Its rugged die-cast aluminium housing is protected by a corrosion-resistant polyester powder coating, making it suitable for harsh industrial and marine environments. The actuator provides IP67 ingress protection as standard, with an optional IP68 rating for applications requiring additional environmental protection. Optional ATEX-certified explosion-proof versions are also available for hazardous areas.

    Intelligent Valve Control

    The AOX-MZ is available with multiple control configurations to meet different automation requirements, including:

    • ON/OFF Control
    • Modulating Control
    • Intelligent Control (ICU)
    • Light Indicating Control (LCU)
    • Fieldbus Communication Systems

    These control options allow seamless integration into modern PLC, SCADA, and distributed control systems, providing accurate valve positioning, remote monitoring, and reliable process automation.

    Easy Commissioning and Maintenance

    The actuator features a non-intrusive infrared commissioning system, allowing configuration, diagnostics, and parameter settings to be completed through the sealed display window without opening the electrical enclosure. This helps maintain the actuator's environmental protection while reducing installation and maintenance time.

    For local operation, the AOX-MZ uses magnetic field controls that eliminate the need for shaft penetrations through the enclosure, improving sealing integrity and protecting internal electrical components from moisture ingress.

    Reliable Manual Override

    A built-in handwheel and automatic clutch mechanism allow the actuator to be operated manually during commissioning, testing, or emergency situations. Manual operation is easily engaged by disconnecting the motor via the changeover handle and is automatically disengaged when motor operation resumes, ensuring safe and reliable operation.

    Engineered for Long-Term Reliability

    The AOX-MZ incorporates several design features that improve durability and simplify installation, including:

    • Double-sealed terminal box for improved electrical protection
    • Accurate mechanical valve position indication
    • High-starting-torque motor design
    • EN ISO 5210 and DIN 3210 mounting compatibility
    • Wide range of output drive kits for different valve types
    • Corrosion-resistant housing for harsh industrial environments
