Set Classic EK - straight, 1/2" x EK, 16 x 2, AL

Product detailed description

Classic EK sets are commonly used in residential and commercial heating systems where radiators are connected to copper or multi-layer ALPEX piping. Installers working on central heating systems often use these kits to ensure precise temperature control and efficient heat distribution. The set is suitable for applications where the system operates at a maximum temperature of 120°C and a nominal pressure of PN 10. The components are designed for compatibility with standard copper and ALPEX pipe dimensions, ensuring a secure and leak-free connection.

These kits are particularly useful in retrofitting older systems or in new builds where the use of ALPEX piping is preferred for its flexibility and thermal efficiency. The installation process involves crimping the fittings to the pipe, ensuring the correct torque is applied to the crimping tool. The nickel-plated brass construction of the valve body provides resistance to corrosion and ensures long-term durability in heating environments.

The operating temperature of +120°C and PN 10 pressure rating are essential for determining the suitability of the set for specific heating systems. These parameters ensure the set can handle typical central heating conditions without failure. The material selection (nickel-plated brass) also plays a role in the valve's resistance to thermal cycling and chemical exposure in the system.

Installation and connection

The installation process begins with preparing the copper or ALPEX pipe to the correct length and ensuring the inner diameter matches the specified 16 x 2 mm dimensions. The crimping tool must be calibrated to the correct torque values: 25–35 Nm for IVAR.TA 4420 and 35–45 Nm for IVAR.TR 4430. The thermostatic valve is then assembled with the head and connected to the pipe using the crimping fittings. A common mistake during installation is incorrect torque application, which can lead to leaks or damage to the fittings. It is also important to ensure the pipe is clean and free of debris before crimping to avoid compromising the seal.

Compatibility and accessories

The Classic EK set is compatible with copper and ALPEX pipes of the specified dimensions. It is designed for use with IVAR.TA and IVAR.TR crimping tools. No additional components are required for standard installation, as the set includes all necessary parts for a complete connection. The set is not interchangeable with other valve types or pipe dimensions without verification of compatibility.

Technical background for designers

The thermostatic valve operates by adjusting the flow of hot water in response to the temperature of the surrounding air. The nickel-plated brass body provides good thermal conductivity and resistance to corrosion, making it suitable for long-term use in heating systems. The integration of the valve into the system depends on the overall design of the piping network and the placement of radiators. The efficiency of the system is influenced by the correct sizing of the valve and the accuracy of the thermostatic head in responding to temperature changes.

Service and operation

The set requires minimal maintenance under normal operating conditions. However, it is recommended to periodically inspect the crimped connections for signs of wear or leakage. The thermostatic head should also be checked for responsiveness to temperature changes. No specific service intervals are provided in the technical documentation, so maintenance should be carried out based on the condition of the system and the manufacturer's recommendations.

Frequently asked questions

Can the Classic EK set be used with copper pipes?
Yes, the set is designed for use with copper and ALPEX pipes of the specified dimensions. The crimping fittings ensure a secure connection to both types of piping.

What is the maximum operating temperature of the set?
The set is rated for a maximum operating temperature of +120°C, making it suitable for standard central heating systems.

What torque values should be used for crimping?
For IVAR.TA 4420, the torque should be between 25–35 Nm. For IVAR.TR 4430, the torque range is 35–45 Nm. These values ensure a secure and leak-free connection.

Is the set suitable for use in high-pressure systems?
The set is rated for a nominal pressure of PN 10, which is suitable for most standard heating systems. It is not designed for use in high-pressure industrial applications.
