Electrothermal head 24V

Product detailed description

This 24V electrothermal head is commonly used in residential and commercial buildings with hydronic floor heating systems. It is typically installed by heating engineers and service technicians to regulate individual heating loops in response to room temperature changes. The actuator connects to a room thermostat and works in conjunction with a thermostatic valve to manage the flow of heating medium. It is suitable for systems where precise temperature control is required in specific zones or rooms.

The device is designed for integration into existing heating systems where electrical control of flow is needed. It is often used in multi-room installations where each floor heating loop requires independent regulation. The actuator is mounted on a pipe thermostatic valve and controlled via a low-voltage electrical signal. The system operates within ambient temperatures up to 60°C, making it suitable for most indoor environments.

Technical parameters

Installation and connection

Installation involves mounting the actuator onto a thermostatic valve using the standard M30x1.5 thread. The actuator must be aligned with the valve stem to ensure correct operation. The 0.8 m control cable (2x0.75 mm²) connects to the room thermostat and must be routed to avoid damage and interference. During installation, it is important to verify that the actuator is securely fastened and that the valve stem moves freely within the actuator's range. Common mistakes include misalignment of the actuator and valve, incorrect cable routing, and failure to check for mechanical resistance in the valve stem.

Compatibility and accessories

This actuator is compatible with thermostatic valves that have an M30x1.5 thread. It requires a room thermostat capable of providing a 24V signal to operate. Additional components such as wiring and mounting hardware may be required depending on the installation. No specific related products are listed for this model.

Technical background for designers

The actuator operates by converting electrical energy into mechanical movement to control the position of a thermostatic valve. The 24V supply is sufficient to drive the motor, which moves the valve stem over a 4 mm range. The materials used are selected for durability and resistance to environmental factors. The integration into the system depends on the control logic of the thermostat and the hydraulic characteristics of the heating loop. The service life and efficiency of the actuator are influenced by the frequency of operation, ambient temperature, and the condition of the connected valve.

Service and operation

Regular inspection of the actuator and connected valve is recommended to ensure continued operation. Checkpoints include verifying the alignment of the actuator with the valve stem, ensuring the cable connections are secure, and confirming that the valve moves freely. No specific service intervals are provided in the technical data.

Frequently asked questions

Can this actuator be used with a standard room thermostat?
Yes, provided the thermostat is capable of supplying a 24V signal. The actuator is designed for compatibility with such control systems.

What is the maximum ambient temperature for operation?
The actuator is rated for ambient temperatures up to 60°C, making it suitable for most indoor environments.

How long does it take for the actuator to fully open or close the valve?
The switching time is 3 minutes, which is typical for this type of actuator and ensures smooth operation.

What is the length of the control cable?
The actuator is supplied with a 0.8 m control cable, which is suitable for most installations. Longer cables may be required for more complex layouts.
