Set M - valve - straight, 1/2" x EK, 15 x 1

Product detailed description

The IVAR M-Valve set is commonly used in residential and commercial heating installations where precise temperature control and reliable connection to radiators are required. Installers working with copper or ALPEX piping systems will find this kit suitable for integration with standard 1/2 inch internal thread radiators. The compact design allows for efficient space utilisation in tight installation areas, while the integrated thermostatic function ensures accurate regulation of heat output. The set is particularly useful in systems requiring direct connection to copper or multilayer piping without the need for additional adapters or fittings.

Typical applications include new installations or system upgrades in domestic and light commercial buildings. The kit is suitable for use in central heating systems where radiators are connected via internal thread fittings. The inclusion of compression fittings ensures a secure and leak-free connection to both copper and ALPEX piping, making it a versatile solution for various pipe materials and installation requirements.

Technical parameters

Installation and connection

Installation begins with preparation of the copper or ALPEX tubing to the specified dimensions. The compression fittings are applied using the recommended torque values: 20-35 Nm for IVAR.TA 4420 and 35-45 Nm for IVAR.TR 4430. The internal thread of the valve must be aligned with the radiator port to ensure a secure connection. It is important to verify the correct orientation of the thermostatic head and to ensure that the compression fittings are tightened to the specified torque to prevent leaks. Common installation errors include incorrect torque application, misalignment of the valve body, and failure to clean the tubing before fitting installation.

Compatibility and accessories

This kit is compatible with radiators featuring a 1/2 inch internal thread, such as those from KORADO, PURMO, and KORAD. The set includes all necessary components for direct connection to copper or ALPEX piping, eliminating the need for additional fittings. However, if the installation involves multiple valves or larger systems, additional sets may be required. The kit is not compatible with other pipe materials or connection types outside the specified copper and ALPEX dimensions.

Technical background for designers

The M-Valve operates by combining a thermostatic head with an integrated valve mechanism to regulate heat output based on room temperature. The nickel-plated brass CW617N material provides high resistance to corrosion and mechanical stress, ensuring long-term reliability in heating systems. The valve is designed for integration with copper and ALPEX piping, where the compression fittings create a secure and leak-free connection. The service life and efficiency of the valve depend on correct installation, including proper torque application and alignment with the radiator. The compact design allows for easy integration into existing systems without requiring major modifications.

Service and operation

Regular inspection of the compression fittings and thermostatic head is recommended to ensure continued performance. The fittings should be checked for signs of wear or leakage, and the thermostatic head should be verified for correct operation. No specific service intervals are provided in the technical data, but any signs of malfunction should be addressed immediately. The valve requires no routine maintenance beyond visual inspection and verification of system performance.

Frequently asked questions

Can the IVAR M-Valve be connected to copper tubing with a different diameter?
No, the valve is specifically designed for copper Ø 15 x 1 mm and ALPEX Ø 16 x 2 mm tubing. Other diameters are not compatible with the compression fittings included in the set.

Is the thermostatic head adjustable?
Yes, the thermostatic head is pre-set for standard operation but can be adjusted according to the manufacturer's technical data sheet to meet specific system requirements.

Can this valve be used with radiators that have a different thread type?
No, the valve is designed for 1/2 inch internal thread radiators. Radiators with other thread types require a different valve model.

What is the recommended tightening torque for the compression fittings?
The recommended torque is 20-35 Nm for IVAR.TA 4420 and 35-45 Nm for IVAR.TR 4430. Incorrect torque application can lead to leaks or damage to the fittings.
