Liquid thermostatic head - M30x1,5; chrome-matt IVAR.T 3000

Product detailed description

Liquid thermostatic heads are essential components in hydronic heating systems, ensuring precise temperature control in individual rooms or zones. Installers and service technicians commonly use these heads in residential and commercial buildings where consistent thermal comfort is required. These systems are typically found in central heating setups with radiators, where each head is mounted on a thermostatic valve to regulate heat output based on ambient temperature. The integration of such heads allows for efficient energy use and improved occupant comfort, particularly in systems where manual adjustments are impractical or insufficient.

When installing these heads, technicians must consider the system’s overall design, including the type of radiators, pipe connections, and the presence of other control mechanisms. The M30x1.5 thread ensures compatibility with a range of valves and compact radiator designs. The chrome-matt finish is chosen for its resistance to fingerprints and wear, making it suitable for high-traffic areas or environments with frequent adjustments.

Technical parameters

Installation and connection

Installation begins with ensuring the thermostatic valve is fully assembled and ready for the head. The M30x1.5 thread must be aligned with the valve’s corresponding port and tightened by hand, followed by a final quarter-turn with a wrench to prevent over-tightening. It is crucial to check for any debris or manufacturing residue in the valve seat before attaching the head to avoid leaks or performance issues. Common mistakes include using incorrect thread sizes or failing to clean the connection surface, both of which can lead to reduced efficiency or system failure.

Compatibility and accessories

This head is compatible with IVAR.VD, VS, VCD, VCR, and M-ventil valves, as well as compact radiator valves with M30x1.5 connections. It also supports the Danfoss Clip-Clap system, allowing for use in mixed systems with different valve manufacturers. For installations requiring temperature locking, the head includes a feature to fix the setting at a desired level. No additional accessories are required for basic installation, though a wrench may be necessary for tightening.

Technical background for designers

The operating principle of this head relies on a liquid-filled sensor that expands or contracts in response to ambient temperature changes. This movement adjusts the valve’s opening, controlling the flow of hot water through the radiator. The chrome-matt finish is made from a durable alloy that resists oxidation and wear, ensuring long-term performance. The head is designed to integrate seamlessly with thermostatic valves, allowing for proportional control of heat output. Factors such as ambient humidity, exposure to direct sunlight, and the frequency of temperature adjustments can influence the head’s service life and efficiency.

Service and operation

Regular visual inspections are recommended to check for signs of wear, corrosion, or leakage around the connection. The head does not require scheduled maintenance, but any issues with temperature regulation should be investigated promptly. If the head becomes unresponsive or fails to maintain the set temperature, it may need to be replaced. No specific service intervals are provided, but adherence to standard system maintenance practices is advised.

Frequently asked questions

Can this head be used with Danfoss valves?
Yes, it supports the Danfoss Clip-Clap system, making it compatible with Danfoss valves in mixed installations.

Is the temperature setting adjustable?
Yes, the head allows for manual adjustment within the +6.5°C to +28°C range and includes a locking feature to maintain the selected setting.

What thread size is required for installation?
The head uses an M30x1.5 thread, which is standard for compact radiator valves and compatible with IVAR and Danfoss systems.

Can this head be used in high-humidity environments?
Yes, the chrome-matt finish is resistant to corrosion and suitable for use in environments with variable humidity levels.
