Actuator ARA661, 3-point, 230V, 6Nm, 120s. 12101300

Valve actuator – precise regulation and reliability

The ESBE ARA661 actuator is an executive component designed to control rotary valves in heating and cooling systems. The device, powered by 230V AC, offers a torque of 6Nm and a cycle time of 120 seconds. Its versatility makes it suitable for both professional and domestic installations. The gear-based construction ensures smooth and precise operation, and the manual override function facilitates servicing and diagnostics.

Construction and application

The ARA661 actuator is designed to work with mixing valves, allowing regulation of heat or cooling flow in the installation. Made of durable materials – aluminum and plastic – it guarantees long-lasting and trouble-free operation even in harsh environmental conditions (ambient temperature from -5°C to 55°C). The IP41 protection class provides resistance to the ingress of solid objects larger than 1mm and splashing water. The length of the connection cable (1.5m) facilitates installation and connection to the control system.

Key features for the installer:

• 3-point control signal: Enables easy integration with existing control systems.
• Manual override: Allows for quick checking of valve operation and its setting in the event of automation failure.
• Compact design: Facilitates installation even in tight spaces.
• Optional auxiliary contacts: Expand the functionality of the actuator, allowing valve status monitoring.
• Versatility: Compatible with various valve brands (connection type depends on the brand).

Benefits for the end user:

• Precise temperature control: Ensures thermal comfort in rooms.
• Reliability: Long-lasting, trouble-free operation minimizes the risk of downtime in the heating/cooling system.
• Energy saving: Optimization of the heating/cooling system operation translates into lower energy bills.
• Quiet operation: Comfortable use without annoying noises.
• Aesthetic appearance: Compact design and careful workmanship affect the aesthetics of the installation.

The ESBE ARA661 actuator is a solid solution for anyone who values precision, reliability and comfort in the operation of a heating or cooling system.
