The Electric Actuator - PACO | ARI is a versatile device designed for precise valve control in industrial settings. It features a thrust force of 0.85 kN and offers various control signals, including 3-point and 0-10V or 2-10V with position transmitter options. The actuator provides a feedback signal of 0-10V DC and includes manual control via a handwheel. It operates within a temperature range of 0°C to +50°C and has an IP 54 enclosure for dust and water protection. The actuator's travel distance is up to 20 mm, with power consumption of 4.1 VA or 4.8 VA depending on the model, and it weighs 1.3 kg. Special smart functions for the ARI-PACO® 0.85 Y model include automatic travel adaptation, direct control with manual mode priority, and variable control and feedback signals. It also features wearless actual value sensing, non-contact motor travel switching, valve blocking protection, error detection, dynamic hysteresis, and zero crossing for accurate operation. The actuator is suitable for applications requiring precise valve position adjustments. Accessories include additional limit switches, a potentiometer for manual position adjustment, and an optional switch board. Wiring diagrams and dimensions are provided, with the actuator body measuring 145 mm x 95 mm x 242 mm. A LED indicator offers visual feedback on the actuator's status, signaling modes such as automatic operation or error detection.
