Product features
- Verified part-turn actuators architecture → SQ actuators are designed for open-close and positioning duty, while SQR is designed for modulating duty.
- Current performance data → The range combines limit and torque sensing, manual operation, mechanical position indication and control options from simple interfaces to microprocessor and fieldbus solutions..
- Manual operating provision → Allows local intervention during commissioning, maintenance or loss of normal remote control.
- High enclosure protection options → Supports reliable operation in demanding industrial and outdoor environments when the correct configuration is selected.
- Corrosion-protection options → Helps extend service life in aggressive atmospheres and reduces the risk of premature external degradation.
- Control and feedback flexibility → Simplifies integration with plant control systems and lets users select only the signals and functions required.
- Diagnostic capability → Provides condition information that can support maintenance planning and reduce avoidable troubleshooting time.
- Modular AUMA platform → Makes it easier to combine actuator, controls and accessories for the required valve and process duty.
- Serviceable construction → Supports lifecycle maintenance, spare-parts planning and repair instead of treating the actuator as a disposable component.
- AxFlow application support → AxFlow can help check valve interface, torque, duty class, controls and environmental requirements before selection.
Reliable valve automation depends on matching the actuator to the valve mechanics, required duty class, control philosophy and site conditions. AUMA SQ and SQR is intended for applications where repeatable remote operation and clear status feedback are important to process continuity, whether the valve is used for isolation, positioning or modulating control.
SQ actuators are designed for open-close and positioning duty, while SQR is designed for modulating duty. Current ranges cover 50 to 2,500 Nm, with 90-degree operating times from 4 to 100 seconds for SQ and 8 to 100 seconds for SQR depending on size and configuration. The operating principle and control architecture are selected to suit the specific valve movement and duty, helping avoid unnecessary mechanical stress and ensuring that the actuator delivers the required movement rather than simply maximum power.
The range combines limit and torque sensing, manual operation, mechanical position indication and control options from simple interfaces to microprocessor and fieldbus solutions. These verified characteristics give engineers a practical basis for comparing actuator size, duty, interfaces and environmental suitability. Exact torque margin, speed, supply, flange/interface, controls, functional-safety requirement and ambient conditions should be checked for the individual valve and project.
From a total-cost-of-ownership perspective, correct sizing and control selection can reduce commissioning issues, unnecessary wear and unplanned intervention. AUMA's serviceable modular architecture also supports maintenance and spare-parts planning over the installed life. AxFlow can support product selection, replacement assessment, service and spare-parts requirements; contact AxFlow for availability and a quote.
