New High Quality Chinese Ball Valve Butterfly Valve and Auma SQ Series Part-turn Actuators
AUMA's SQ 05.2 – SQ 14.2 and SQR 05.2 – SQR 14.2 are electric part-turn actuators designed for automating industrial valves, such as butterfly or ball valves, with swing angles typically around 90°. These actuators are available in open-close (SQ) and modulating (SQR) versions, integrated with various control options including AUMA NORM (basic), SEMIPACT (compact), AUMA MATIC (integral), and AUMATIC AC 01.2 (advanced with fieldbus). Certified under UKCA for compliance with Machinery Safety Regulations 2008, they ensure safe incorporation into final machinery for valve operation. Built for reliability in industrial environments, they feature electric motor drive, manual handwheel override, and non-intrusive settings in advanced models.
- Versatile Duty Types: SQ for short-time open-close (S2 - 15/30 min), SQR for intermittent modulating (S4 - 25/50%, S5 - 25%) with up to 1,500 starts/hour.
- Torque and Swing Flexibility: Adjustable tripping torque, swing angles from 75° to 105° (options 15°-135°), with mechanical end stops for precise manual positioning.
- Control Integration: Supports parallel control, Profibus DP, Modbus, Foundation Fieldbus; non-intrusive limit/torque setting via Bluetooth in AUMATIC.
- Safety and Protection: Overload/temperature monitoring, phase correction, EMERGENCY behaviors; complies with SIL requirements in select configurations.
- Diagnostic Capabilities: Logging of runtime, starts, torque curves; NAMUR NE 107 status signals for maintenance alerts.
- Rugged Construction: IP68 enclosure (submersion up to 8m/96 hours), vibration resistance 1g (10-200 Hz), corrosion protection KS/KX.
- Manual Operation: Lockable handwheel with torque bypass (0-5s) for emergency; signal indication for manual mode.

These actuators are ideal for automating part-turn valves in industries such as water treatment, power generation, chemical processing, and wastewater management. SQ models suit open-close operations in pipelines and tanks, while SQR excels in modulating duties for flow/pressure control. Suitable for non-explosive areas with optional Ex zone 22 dust certification; not for buried service or continuous underwater use.
What regulations do these actuators comply with?
UKCA for Machinery Safety (S.I. 2008 No. 1597), RoHS (S.I. 2012 No. 3032), EMC (S.I. 2016 No. 1091), Radio Equipment (S.I. 2017 No. 1206), and Electrical Safety (S.I. 2016 No. 1101).
Can they be used in hazardous areas?
Optional for Ex zone 22 dust (II3D IP6X T150°C); not for gas explosive zones without specific variants.
How do I integrate with control systems?
Via parallel inputs or fieldbus protocols like Profibus DP, Modbus, Foundation Fieldbus in AUMATIC controls.
What if the actuator is modified?
Unauthorized modifications void the declaration; contact AUMA for support.
Are they suitable for high-vibration environments?
Yes, resistant to 1 g vibrations from 10-200 Hz, ideal for industrial plants.
