Variable speed actuator SEVEN

Use of a specially developed frequency converter offers tremendous advantages. The most important features are variability in speed, resistance against voltage and frequency fluctuations, no current peaks during start-up as well as gentle operation of the valve by reducing speed in end positions. The robust design is extremely resilient against environmental influences (standard corrosivity class C5, IP67, double sealed – protection is also ensured during commissioning) and can be further enhanced as an option.


The SEVEN actuator is available in three electronics variants: ECOTRON, PROFITRON and HiMod.

Product Features
