Actuator - EMOtec, NC 24V, First-Open, 4mm stroke 1806-17.500

Thermal actuator for precise regulation

The EMOtec First-Open thermal actuator is an advanced solution for two-point temperature and time regulation in heating systems. Thanks to the First-Open function, the device keeps the valve open until the room control is activated, ensuring a safe system startup.

Intelligent First-Open function

The key feature of this actuator is the First-Open function, which automatically keeps the drive in the open position until individual control is activated. This intelligent function eliminates the risk of improper heating installation startup and ensures the safe activation of the entire system.

Robust construction and protection

The housing, made of high-temperature and impact-resistant plastic, guarantees long-term operation in demanding industrial conditions. The IP54 protection rating ensures reliable operation in all mounting positions, protecting against dust and moisture.

Precise regulation and control

The actuator offers a 4mm stroke with a 180 second duty cycle, allowing for smooth regulation of the medium flow. The built-in position indicator enables easy monitoring of the valve's operating status without the need to disassemble the device.

Wide compatibility

The device fits all Heimeier thermostatic valve components and three-way valves, making it a universal solution for modernizing existing heating installations.

Operational safety

The actuator meets CE certificate requirements and protection class II, ensuring full electrical safety during operation. An operating temperature range from 0°C to 60°C guarantees reliability in various environmental conditions.

Easy installation and maintenance

A standard 1 meter cable terminated with 2x0,75 mm² cross-section wires facilitates installation without the need for specialized tools. The design allows for quick mounting and disassembly for servicing purposes.

Power parameters

A supply voltage of 24V AC/DC with a tolerance of ±20%/-10% and an operating frequency of 0-60 Hz ensures stable operation in various network conditions. A rated power of 2VA in continuous mode and a maximum of 6VA during the switching phase guarantees economical energy consumption.
