AOX-MZ Multi-Turn Electric Actuator: The Smart Choice for Reliable Valve Automation in South Africa. Reliable Valve Automation for Demanding Industries.
Industrial valve automation requires equipment that delivers precision, reliability, and long service life. Whether you’re operating a water treatment plant, mining operation, chemical processing facility, or power station, selecting the right electric actuator is essential for maintaining safe and efficient processes.
The AOX-MZ Multi-Turn Electric Actuator has been engineered to automate multi-turn valves with exceptional performance, offering intelligent control, rugged construction, and flexible integration into modern industrial automation systems. Available from KVC Africa, the AOX-MZ provides a dependable solution for businesses across South Africa looking to improve operational efficiency and reduce maintenance costs.
What Is a Multi-Turn Electric Actuator?
Unlike quarter-turn actuators used for ball and butterfly valves, a multi-turn electric actuator is designed to rotate the output shaft through multiple revolutions. This makes it ideal for operating valves that require linear stem movement, such as:
- Gate valves
- Globe valves
- Sluice valves
- Rising stem valves
The AOX-MZ is specifically designed for these applications while also being adaptable for other valve types when used with appropriate gearboxes or mechanical drive systems.
Why Choose the AOX-MZ Multi-Turn Electric Actuator?
High Starting Torque
Many industrial valves require significant force to break away from their fully closed position. The AOX-MZ features specially designed motors that deliver high starting torque, ensuring smooth and reliable valve operation even under demanding conditions. It is available with three-phase AC, single-phase AC, and DC motor options to suit different installations.
Intelligent Valve Control
Modern industrial plants demand more than simple open-and-close operation. The AOX-MZ supports multiple control configurations, including:
- ON/OFF control
- Modulating control
- Intelligent control (ICU)
- Light indicating control (LCU)
- Fieldbus communication
These options allow seamless integration with PLC and SCADA systems, enabling precise valve positioning, remote monitoring, and advanced diagnostics.
Simple Commissioning
Commissioning an actuator should not compromise its environmental protection. The AOX-MZ offers non-intrusive infrared commissioning, allowing settings and diagnostics to be completed without opening the enclosure. This helps preserve the actuator’s IP rating while reducing installation time.
Built for Harsh Environments
Industrial environments often expose equipment to dust, moisture, chemicals, and extreme temperatures. The AOX-MZ is designed to perform reliably with features including:
- IP67 enclosure as standard
- Optional IP68 protection
- Corrosion-resistant aluminium housing
- Polyester powder-coated finish
- Stainless steel fasteners
- Optional explosion-proof models for hazardous areas.
Applications Across South African Industries
The AOX-MZ is used in a wide range of industrial sectors where reliable valve automation is essential.
Water and Wastewater Treatment
Water treatment facilities rely on automated gate and sluice valves to control water flow efficiently. The AOX-MZ delivers accurate positioning and dependable operation in challenging outdoor environments.
Mining
Mining operations require robust equipment capable of withstanding dust, vibration, and demanding operating conditions. The AOX-MZ’s rugged construction makes it well suited for mineral processing plants and mine infrastructure.
Oil and Gas
Optional explosion-proof configurations make the AOX-MZ suitable for hazardous environments where safety and reliability are critical.
Power Generation
Power stations use multi-turn actuators to automate steam, cooling water, and auxiliary process valves, ensuring consistent process control and improved operational efficiency.
Chemical Processing
Corrosion-resistant materials and intelligent control options make the AOX-MZ an excellent choice for chemical plants requiring precise valve operation in aggressive environments.
Easy Maintenance and Long Service Life
The AOX-MZ has been designed with maintenance in mind. Features such as:
- Double-sealed terminal box
- Manual override handwheel
- Mechanical valve position indicator
- Non-intrusive setup
- Robust gear design
help minimise downtime while extending the service life of the actuator. These design features contribute to lower maintenance costs and improved operational reliability.
