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.
Design features ECOTRON:
- Torque range up to 4000 Nm / 2800 Nm (Inching/Modulating)
- Variable output speeds up to 160 rpm / 80 rpm (Inching/Modulating)
- Variants in modulating classes A (On/Off), B (Inching) and C (Modulating) according to EN 15714-2
- Symbol LC display with “Drive Controller“ for simple commissioning
Design features PROFITRON:
- Torque range up to 4000 Nm / 2800 Nm (Inching/Modulating)
- Variable output speeds and complex speed functions up to 160 rpm / 80 rpm (Inching/Modulating)
- Variants in modulating classes A (On/Off), B (Inching) and C (Modulating) according to EN 15714-2
- Full graphic user interface with “Drive Controller“, intuitive operation
- Many options for parameterization and process adjustment
- External USB port and Bluetooth connection standard
Design features HiMod:
- Torque range up to 2800 Nm (continuous modulation) Variable output speed up to 80 rpm (continuous modulation)
- Continuous modulation class D according to EN 15714-2
- Full graphic user interface with „Drive Controller“ control button, intuitive operation
