ESBE ARA6X9 Proportional Actuator (600 Series) for VRG/VRB Mixing Valves

🚀 The Highest Level of Precision in Flow Regulation

He ESBE ARA6X9 Proportional Actuator It represents the most advanced control technology in the ARA600 Series. Designed to operate rotary valves DN15-50This actuator is essential for systems that require a continuous and highly precise regulation of the temperature, based on an analog input signal (e.g. 0-10 V either 4-20 mA).

This functionality is the ideal solution for complex mixing applications where even minimal deviations in the control signal require immediate and proportional valve adjustment. ARA639In particular, it offers monitoring and quick-start features that set a new standard for Authority and Experience in hydronic control.

✨ EEAT and Benefits: High-End Closed-Loop Control

Choosing an ARA6X9 proportional actuator is the key investment for maximum efficiency and precision in control.

• Analog Regulation (Proportional Control): It allows continuous and ultra-precise modulation of the valve, directly proportional to the received control signal (the most accurate control available).
• Multi-System Compatibility: In addition to proportional control, the ARA639 models can be configured to operate with signals from 3 points and 2 pointsoffering unprecedented versatility.
• Advanced Monitoring (ARA639): It has a proportional analog output signal to monitor the valve position, integrating device monitoring into BMS (Building Management System) systems.
• Quick Start: It incorporates positioning memory to return to the last known position after a power failure, minimizing disruptions to the system.
• Easy Coupling: Includes adapter kit Ref. ESBE 16000500 for a direct and stable installation in the series VRG, VRB, VRH and many more.

❓ Frequently Asked Questions (FAQ) Technical

💡 What is the application difference between 3-point control and proportional control?

The 3-point (modulating) control uses time pulses to move the valve, being precise but slower. Proportional (ARA6X9) uses a constant voltage or current signal (e.g. 0-10 V), by moving the valve to an exact position and holding it there continuously. Proportional control is more precise and more common in centralized management systems (BMS).

💡 Does the "Positioning Memory" function make the actuator more reliable?

Yes, it significantly increases system reliability. The positioning memory allows the actuator, after a power outage and restoration, to instantly return to the exact position it held before the failure. This minimizes circuit deregulation time, which is crucial in critical systems.

💡 Why are there only versions of 24 V AC/DC available for proportional control?

Analog (proportional) control systems are inherently sensitive to electrical noise. Low voltage (24 V AC/DC minimizes interference, ensuring the clarity and stability of the control signal. For this reason, most advanced automation systems use this voltage.
