Actuator ARA639, 24V, 6Nm, 15/30/60/120s, control signals: 010 V, 210 V, 020 mA, 420 mA 12520100

Electric actuator for mixing valves – precision and reliability in a compact housing

This actuator from the ARA600 series by ESBE is an ideal solution for controlling mixing valves in heating and cooling systems. Designed to work with VRG130 and VRB140 valves, it allows for precise adjustment of the mixing ratio throughout the operating range. Thanks to the possibility of voltage (0-10V) and current (4-20mA) control, the actuator offers flexibility and accuracy, essential in modern installations.

Functionality and application

The ARA639 actuator is designed to handle mixing functions, ensuring optimal system performance. Its compact design (width 105 mm, height 88 mm, depth 77 mm) makes it easy to install even in tight spaces. A torque of 6 Nm guarantees effective operation, and a rotation angle of 90° provides full flow control. The possibility of manual operation – thanks to the removable knob – is an additional advantage in emergency situations or during servicing.

Key features and benefits

• Versatile control: Support for 0-10V and 4-20mA signals allows integration with various control systems.
• Compact size: Facilitates installation in limited space.
• Durable construction: The housing made of high-quality materials ensures long-lasting and reliable operation in temperatures from -5°C to 55°C.
• Protection class IP41: Provides protection against the ingress of solid objects larger than 1mm and against condensation.
• Manual operation possible: Enables quick intervention in the event of a failure or the need for adjustment without using the automation system.
• Optional auxiliary contacts: Expand the functionality of the actuator, allowing connection of additional signaling or control devices.
• Gearbox: Ensures smooth and precise operation of the actuator.
• Cycle time 15 seconds: Fast response to control signals.

The ARA639 actuator is a solid and reliable solution for professionals and users looking for an effective way to control mixing valves in their heating and cooling installations.
