Servo drive, 230 V; 5 Nm

Product detailed description

This electric actuator is commonly used in heating systems where precise control of mixing valves is required. It is typically installed in residential and commercial buildings to regulate the flow of heating media in central heating systems. The actuator ensures accurate positioning of the valve to maintain desired temperature and flow conditions. It is designed for integration with IVAR mixing valves and boiler assemblies, allowing for automated control while retaining the option for manual override in case of power failure or maintenance.

When installing this actuator, it is important to consider the system's hydraulic and electrical requirements. The actuator must be connected to a compatible valve and powered by a stable 230 V supply. The 90° rotation angle and 5 Nm torque are suitable for standard mixing valve applications, ensuring reliable operation under normal load conditions. The IP41 rating provides protection against dust and splashing water, making it suitable for indoor installation in technical rooms or boiler houses.

The 5 Nm torque is sufficient for most standard mixing valve applications, ensuring smooth and accurate valve positioning. The 90° rotation angle corresponds to the full stroke of the connected valve, allowing for complete opening and closing. The 140 s time constant indicates the time required for the actuator to complete a full stroke, which is important for system response time and control accuracy. The IP41 rating ensures protection against dust and water ingress, but it is not suitable for outdoor or high-moisture environments.Installation and connection The actuator is installed directly onto the valve stem or actuator rod of the mixing valve. It requires a 230 V AC power supply at 50/60 Hz. Ensure the electrical connections are made in accordance with local regulations and the manufacturer's instructions. The actuator must be mounted in a position that allows for free rotation and does not interfere with the valve body. Check that the mechanical linkage between the actuator and the valve is correctly aligned to prevent binding or misalignment. Common installation errors include incorrect electrical wiring, misalignment of the actuator with the valve stem, and failure to secure the actuator properly to the valve body.

Compatibility and accessories

This actuator is compatible with IVAR MIX 3, MIX 4 and boiler assemblies. It is designed for use with the IVAR.ACTUATORS 05 series. No additional accessories are required for standard installation, but ensure the control system is compatible with the actuator's electrical requirements. No related products are specified for this model.

Technical background for designers

The actuator operates using an electric motor that rotates the output shaft through a gear system. The motor is controlled by an internal circuit that responds to electrical signals from the control system. The materials used are selected for durability and resistance to mechanical stress and environmental factors. The actuator integrates with the control system via standard electrical connections and is designed to operate reliably under normal system conditions. The service life and efficiency are influenced by the quality of the electrical supply, the alignment with the valve, and the operating environment.

Service and operation

Regular inspection of the actuator's electrical connections and mechanical linkage is recommended to ensure continued reliable operation. Check for signs of wear or damage to the motor and gears. No specific service intervals are provided in the brief, but any malfunction should be addressed promptly to prevent system disruption. Ensure the actuator is operating within its specified torque and temperature limits.
