Valve Actuators

The Ronk Add-A-Phase Type HD power converter is designed for valve actuators and other applications that must operate in harsh work environments. Type HD converters are built with heavy duty components to withstand extreme temperatures and frequent start-and-stop operation. They provide reliable, energy efficient operation.

Ronk Add-A-Phase power converters produce balanced three-phase power to operate three-phase motors from single-phase power units. They can operate motors at their full load rating, plus normal overload, but can also be adjusted for motors operating at lower, consistent horsepower loads. This feature extends motor life, and helps Add-A-Phase converters run at extremely high efficiency—approximately 97% compared to the typically less than 90% efficiency of standard converters.
