Chinese Butterfly Globe Valve Body AUMA SQ Part-turn SA Multi-turn Electric Control Valve Actuators
The SQ 05.2 – 14.2 (open-close) and SQR 05.2 – 14.2 (modulating) from AUMA are electric part-turn actuators certified under UKCA for incorporation into valve machinery. Driven by 3-phase AC motors with self-locking gearing, they provide adjustable torque for 90° operations. Paired with controls like AUMA NORM, SEMIPACT, MATIC, or AUMATIC AC 01.2, they support advanced features including fieldbus integration. These actuators ensure compliance with UK safety standards (Machinery, Electrical, EMC, RoHS, Radio), making them reliable for industrial valve automation.
- Duty Classification: SQ: S2 short-time (15/30 min); SQR: S4/S5 intermittent (25/50%) for modulating with high start rates.
- Torque Management: Adjustable tripping, limit/torque seating; mechanical position indicator and end stops.
- Motor and Protection: Asynchronous motor with F/H insulation, thermoswitches/PTC; automatic phase correction.
- Advanced Controls: AUMATIC with LC display, Bluetooth, logging (events, torque); NAMUR NE 107 signals.
- Safety Integration: Programmable EMERGENCY, overload protection; SIL-capable in configurations.
- Environmental Specs: IP68 submersion, 100% RH, KS/KX corrosion; vibration tolerance per EN standards.
- Feedback and Inputs: Galvanically isolated analogue outputs; up to 12 contacts; 24-115 V inputs.
