Set AVK Vekoluxivar - straight, 1/2" x EK, 15 x 1, CU

Product detailed description

Two-pipe heating systems in residential and commercial buildings require reliable and precise control of heat distribution. Installers and service technicians working on such systems often encounter the need to integrate thermostatic controls with existing pipe configurations. The AVK Vekoluxivar kit is designed for these applications, offering a complete solution for connecting radiators with 1/2 inch internal thread to copper or ALPEX multilayer piping. This kit ensures accurate temperature regulation and secure hydraulic connections, making it suitable for both new installations and system upgrades.

When installing this kit, the system must accommodate the specific dimensions and connection types. The straight configuration of the kit allows for straightforward integration into standard piping layouts, while the included compression fittings ensure a leak-free connection to copper or multilayer pipes. The thermostatic head provides local temperature control, allowing for zoned heating where required.

Technical parameters

Installation and connection

The AVK Vekoluxivar kit is installed using a combination of compression fittings and threaded connections. The 1/2 inch internal thread allows for direct connection to radiators with compatible valve inlets. The compression fittings connect to copper or ALPEX multilayer pipes with an outer diameter of 15 mm and a wall thickness of 1 mm. During installation, it is important to ensure that the compression rings are properly seated and that the tightening torque is within the specified range: 20–35 Nm for the thermostatic head (IVAR.TA 4420) and 35–45 Nm for the compression fitting (IVAR.TR 4430).

Compatibility and accessories

This kit is specifically designed for radiators with a valve inlet thread of M 30 x 1.5. It is compatible with copper or ALPEX multilayer pipes of the specified dimensions. No additional accessories are required for standard installation. However, if the system includes radiators with different connection types or dimensions, alternative kits may be necessary.

Technical background for designers

The AVK Vekoluxivar kit operates by combining a thermostatic head with a control and shut-off valve. The thermostatic head responds to ambient temperature changes and adjusts the flow of heating fluid through the valve. The nickel-plated brass construction provides resistance to corrosion and ensures long-term reliability in wet environments. The kit is integrated into the system through the specified compression fittings, which provide a secure and leak-free connection. The efficiency of the system depends on proper sizing of the valve and correct installation of the fittings. The service life is influenced by the quality of the installation, the operating conditions, and the maintenance performed.

Service and operation

Regular inspection of the compression fittings and thermostatic head is recommended to ensure continued performance. Check for signs of wear, leakage, or damage to the sealing rings. The tightening torque should be verified periodically to ensure that it remains within the specified range. If any issues are detected, the affected components should be replaced according to the manufacturer's guidelines. No specific service intervals are provided in the brief; however, routine maintenance is advised to maintain system efficiency and prevent failures.
