Electric actuator troubleshooting should begin with the fault indication, local or remote operating mode, available power and the valve’s mechanical condition. Repeatedly resetting a trip or raising the torque setting can hide the cause and risk damage to the valve...

A modulating electric actuator moves a valve to intermediate positions in response to a control signal. Unlike an open-close actuator, it can position the valve between its end stops. Selecting a modulating electric actuator requires attention to both the control...

Manual valve automation allows an existing valve to be operated by an actuator instead of a handwheel or lever. A successful retrofit starts with the valve’s condition, operating load, mounting arrangement and control requirements. Buying an actuator before checking...

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....

Introduction Selecting the correct electric actuator is not only about knowing the valve size. A reliable actuator selection depends on several technical factors, including valve type, torque requirement, operating conditions, control requirements, and environmental...

Introduction Valve automation plays a critical role in modern industrial plants. Whether used in water treatment, mining, power generation, manufacturing, or process industries, actuators allow valves to be operated safely, efficiently, and reliably. Two of the most...

The Hidden Cost of Incorrect Actuator Sizing When automating a valve, selecting the correct actuator is one of the most important decisions in the entire project. While many people focus on valve size alone, proper actuator sizing requires a detailed understanding of...
