Set M - valve - straight, 1/2" x EK, 16 x 2

Product detailed description

This M-Valve kit is commonly used in residential and commercial heating systems where precise temperature control and reliable connections are required. It is suitable for installations involving copper or multi-layer ALPEX piping, and is typically used with radiators or heating bodies that have a 1/2 inch internal thread. The kit is designed for direct installation, ensuring compatibility with standard heating circuits and simplifying the integration of thermostatic control into the system.

Installers working with modern heating systems often encounter the need to connect radiators to either copper or ALPEX piping. This M-Valve kit provides a complete solution by combining a thermostatic head with a compact fitting that includes an integrated valve and compression fittings. The design ensures a secure and leak-free connection, while the pre-set configuration reduces the need for on-site adjustments, saving time during installation.

The valve is constructed from nickel-plated brass CW617N, a material known for its corrosion resistance and durability in heating applications. The 1/2 inch internal thread allows for direct connection to standard radiators, while the EK 16 x 2 configuration ensures compatibility with ALPEX tubing. The pre-set configuration simplifies system balancing, and the specified tightening torques for the compression fittings ensure a secure and long-lasting connection.

Installation and connection

The installation process begins with preparing the copper or ALPEX tubing to the correct length and ensuring the internal thread of the radiator is clean and undamaged. The compact fitting is then threaded onto the radiator, followed by the installation of the compression fittings onto the copper or ALPEX tubing. The tightening torque must be strictly followed: 20–35 Nm for IVAR.TA 4420 and 35–45 Nm for IVAR.TR 4430. It is important to check that all connections are tight and that there is no visible damage to the tubing or fittings. A common mistake during installation is over-tightening the compression fittings, which can damage the sealing surfaces and lead to leaks. Another frequent error is using incorrect thread types or sizes, which can result in misalignment and improper sealing.

Compatibility and accessories

This M-Valve kit is specifically designed for radiators with a 1/2 inch internal thread, such as those from KORADO, PURMO, and KORAD. It is compatible with copper tubing (Ø 15 x 1 mm) and ALPEX multi-layer tubing (Ø 16 x 2 mm). No additional accessories are required for basic installation, as the kit includes all necessary components. However, installers should ensure that the system is equipped with the correct tools for cutting and preparing the tubing, as well as torque wrenches for tightening the compression fittings to the specified values.

Technical background for designers

The M-Valve operates by allowing the thermostatic head to regulate the flow of hot water through the radiator based on the ambient temperature. The nickel-plated brass construction ensures resistance to corrosion and long-term stability in wet environments. The compact fitting integrates the valve and compression fittings into a single unit, reducing the number of components and potential leak points. The use of ALPEX tubing allows for flexibility in routing and reduces the need for additional fittings. The pre-set configuration of the valve helps maintain system balance without requiring manual adjustments, making it suitable for both new installations and system retrofits.

Service and operation

Regular inspection of the compression fittings and the thermostatic head is recommended to ensure continued performance. The tightening torque should be rechecked periodically, especially after the initial weeks of operation when settling may occur. No specific service intervals are provided in the brief, but any signs of leakage or reduced efficiency should be addressed immediately. The thermostatic head can be adjusted if necessary, but it is generally left in the pre-set position unless system balancing is required.

Frequently asked questions

Can the M-Valve be used with copper tubing of a different diameter?
No, the M-Valve is specifically designed for copper tubing with a diameter of 15 x 1 mm and ALPEX tubing with a diameter of 16 x 2 mm. Using a different diameter may result in improper sealing and potential leaks.

Is the thermostatic head adjustable?
Yes, the thermostatic head can be adjusted to control the temperature of the radiator. However, the valve is pre-set for standard operation and does not require frequent adjustments under normal conditions.

Can the M-Valve be used in a system with multiple radiators?
Yes, the M-Valve is suitable for use in systems with multiple radiators. Each radiator should be equipped with its own M-Valve to ensure individual temperature control and system balance.

What tools are required for installation?
A torque wrench is required to tighten the compression fittings to the specified values. Additionally, standard plumbing tools such as a pipe cutter and deburring tool are needed for preparing the copper or ALPEX tubing.
