The use of a frequency converter specially conceived for the actuator deployment offers many advantages. Besides the variable speed, the insensitivity to voltage and frequency variations, the lack of current increase during motor start-up as well as the valve protection by soft approaching of the end positions should be mentioned.
The rugged design makes these actuators extremely resistant to environmental impacts (standard corrosivity category C5, IP67, double sealed - enclosure protection is also ensured during commissioning) and can be further enhanced as an option.
The SEVEN actuator is available in three electronic variants: ECOTRON, PROFITRON and HiMod.
