Electrothermal head - for dynamic balancing valves - 24V; 0-10V IVAR.TE 3003

Product detailed description

Electrothermal heads are essential components in modern hydronic systems where precise flow control is required. They are commonly found in commercial and residential buildings equipped with dynamic balancing valves. Installers working on heating systems or plumbing networks often encounter these devices when integrating automated flow regulation. The electrothermal head allows for proportional control of water flow, ensuring consistent performance even in variable load conditions.

The IVAR TE 3003 electrothermal head is specifically designed for integration with dynamic balancing valves. It supports both ON/OFF control at 24V and modular control through a 0–10V signal. This makes it suitable for applications where flow needs to be adjusted continuously based on system demand. The M30 x 1.5 thread ensures a secure and leak-free connection to the valve body.

Brand	IVAR

The technical parameters define the operational range and compatibility of the electrothermal head. The 24V ON/OFF function is ideal for basic control loops, while the 0–10V input allows for more sophisticated modulation. These settings influence how the device integrates into larger control systems and should be considered during sizing and selection to ensure proper system response and stability.

Installation and connection

During installation, the electrothermal head is mounted onto the valve body using the M30 x 1.5 external thread. The connection should be tightened to the manufacturer’s recommended torque to prevent leaks and ensure mechanical integrity. The electrical connections require a separate terminal block or control unit capable of supplying 24V DC or a 0–10V signal. Before energising the system, the installer should verify correct polarity and insulation resistance to avoid damage. Common installation errors include incorrect thread orientation and failure to align the actuator with the valve’s travel range. To avoid these, always refer to the manufacturer’s installation instructions and perform a visual alignment check after mounting.

Compatibility and accessories

This electrothermal head is compatible with IVAR PICC 03 and PICC 13 actuators, which provide the necessary control signals for operation. For complete system functionality, a compatible controller or building management system capable of generating 0–10V outputs must also be installed. Additional components such as terminal blocks, junction boxes and control modules may be required depending on the system configuration. When planning the installation, ensure that all components are correctly matched in terms of voltage, signal type and mechanical interface.

Technical background for designers

The electrothermal head operates by converting electrical input signals into mechanical movement, which adjusts the position of the valve plug within the valve body. The internal mechanism is typically made of durable, corrosion-resistant materials to withstand long-term exposure to water and thermal cycling. The 0–10V signal provides a linear relationship between input and flow rate, allowing for precise modulation. Integration into the system requires careful consideration of the control loop dynamics and the need for feedback mechanisms to maintain setpoints. The service life of the device is influenced by factors such as operating temperature range, frequency of actuation and the quality of the electrical supply.

Service and operation

Routine service includes checking the mechanical connection for signs of wear or leakage and verifying the integrity of the electrical connections. No scheduled service intervals are specified in the technical documentation. During operation, the installer should monitor the system for unusual noise or erratic valve movement, which could indicate a fault in the control signal or internal component wear. If a problem is detected, the device should be isolated and inspected for damage or misalignment.

Frequently asked questions

Can the TE 3003 be connected to a 0–10V controller?
Yes, the device accepts a 0–10V input for proportional control. Ensure the controller is configured for the correct signal range and polarity.

Is the TE 3003 compatible with PICC 03 and PICC 13 actuators?
Yes, the electrothermal head is specifically designed for use with these actuators. Confirm that the mounting dimensions and electrical interfaces match the specifications.

What type of thread is used for installation?
The device features an M30 x 1.5 external thread for secure connection to the valve body. Use a suitable wrench to tighten the fitting according to the manufacturer’s guidelines.

Can this head be used with 230V systems?
No, the TE 3003 is rated for 24V operation only. Connecting it to a 230V supply will result in immediate damage to the internal electronics.
