Set Classic EK - corner, 1/2" x EK, 15 x 1, CU

Product detailed description

This EK corner set is commonly used in residential and commercial heating systems where precise control over radiator temperatures is required. Installers working with copper or multi-layered ALPEX piping will find this set suitable for ensuring secure and efficient connections. The components are selected for compatibility with standard pipe sizes and allow for integration into both new and retrofit heating systems.

The assembly includes a thermostatic head, a thermostatic valve, and both regulating and compression fittings. This ensures that the system can maintain consistent performance while allowing for adjustments based on room conditions. The nickel-plated brass construction provides resistance to corrosion and ensures long-term reliability in a variety of environments.

Technical parameters

Installation and connection

The set is intended for use with copper or ALPEX multi-layered pipes. The compression fittings require careful tightening to the specified torque values to ensure a leak-free seal. The connection size is 1/2 inch, which aligns with standard pipe dimensions in many European heating systems. Before final tightening, installers should verify that the pipe ends are clean and free from burrs to prevent damage to the sealing surfaces.

A common mistake during installation is over-tightening the fittings, which can cause deformation of the sealing rings and lead to leaks. It is also important to ensure that the thermostatic head is aligned correctly with the valve to avoid misalignment issues that could affect control accuracy. The tightening torque for the IVAR.TA 4420 fitting is 25–35 Nm and for IVAR.TR 4430 it is 35–45 Nm.

Compatibility and accessories

This EK corner set is specifically designed for use with copper or multi-layered ALPEX piping. It is compatible with standard pipe diameters and requires no additional adapters for typical applications. When installing, ensure that all components are from the same set to maintain consistency in material and performance characteristics. No additional products are required for basic installation.

Technical background for designers

The set operates by allowing controlled flow through the thermostatic valve, which adjusts based on ambient temperature. The nickel-plated brass CW617N material offers good mechanical strength and resistance to corrosion, making it suitable for long-term use in wet environments. The sealing rings used in the compression fittings are designed to maintain integrity under normal operating conditions. The overall system integration depends on proper sizing and positioning within the heating circuit to ensure even distribution of heat and minimal pressure loss.

Efficiency and service life are influenced by the quality of installation, particularly the cleanliness of the pipe ends and the accuracy of the tightening torque applied. Regular inspection of the fittings for signs of wear or leakage can help identify potential issues early.

Service and operation

No specific service intervals are provided in the technical documentation. However, it is recommended to periodically inspect the compression fittings for signs of leakage or wear, especially after initial installation or following periods of high usage. Any visible damage to the sealing surfaces should be addressed promptly to prevent system inefficiencies or potential failures.
