Liquid thermostatic head - with remote valve control - 5m IVAR.T 5030

Product detailed description

This liquid thermostatic head is commonly used in residential and commercial heating systems where precise temperature control is required. It is typically installed in conjunction with radiators and compact valves, allowing for remote adjustment of flow rates in response to ambient temperature changes. The 5m capillary enables flexibility in positioning the control head away from the valve, which is particularly useful in tight or inaccessible spaces. The system is designed to integrate with a range of IVAR valves, ensuring compatibility across different installation scenarios.

Thermostatic heads of this type are often found in systems where individual room control is necessary, such as in multi-room buildings or where zoning is implemented. The M30 x 1.5 thread ensures secure and leak-free connections to the valve body. The temperature range of +6.5°C to +28°C allows for fine-tuning of heating output, adapting to varying thermal demands in different environments.

Technical parameters

Installation and connection

Installation involves connecting the thermostatic head to the valve body using the M30 x 1.5 thread. The capillary should be routed carefully to avoid kinks or damage that could affect its performance. The head should be mounted in a location free from direct heat sources or drafts to ensure accurate temperature sensing. A common mistake during installation is failing to secure the capillary properly, which can lead to reduced responsiveness or mechanical failure over time. Always verify that the connection is tight and that the capillary is not obstructed.

Compatibility and accessories

This thermostatic head is compatible with IVAR VD, VS, VCR, VCD, VCS, and M-ventil valves. It is also suitable for use with radiators that have a M30 x 1.5 connection. No additional accessories are required for standard installation, but it is important to ensure that the selected valve is correctly sized for the system. No related products are specified for this model.

Technical background for designers

The operating principle of this thermostatic head is based on the expansion and contraction of a liquid within the capillary in response to temperature changes. As the ambient temperature rises, the liquid expands, pushing the valve to reduce flow. Conversely, when the temperature drops, the liquid contracts, allowing the valve to open and increase flow. The materials used are selected for their durability and resistance to thermal cycling. The integration of this head into the system ensures stable and responsive temperature control, with the capillary length allowing for remote placement without compromising performance. The service life and efficiency are influenced by the quality of installation, the absence of mechanical stress on the capillary, and the correct pairing with compatible valves.

Service and operation

Regular visual inspections are recommended to check for signs of wear, leakage, or capillary damage. No specific service intervals are provided in the brief, but any issues with responsiveness or flow control should be investigated promptly. The system should be tested periodically to ensure that the head is responding correctly to temperature changes. If the capillary becomes kinked or damaged, it should be replaced to restore full functionality.

Frequently asked questions

Can this head be used with all IVAR valves?
It is compatible with IVAR VD, VS, VCR, VCD, VCS, and M-ventil valves. Always confirm compatibility with the specific valve model before installation.

Is the capillary length adjustable?
The 5m capillary is fixed in length and cannot be modified. It is designed to provide sufficient flexibility for most installation scenarios.

Can the head be mounted in a different orientation?
The head should be mounted in a position that allows for accurate temperature sensing. Avoid placing it in direct sunlight or near heat sources that could interfere with its operation.

What should be checked during installation?
Ensure the M30 x 1.5 connection is secure and that the capillary is routed without kinks. Verify that the head is installed in a location free from drafts and direct heat sources for optimal performance.
