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

Product detailed description

Corner M-valve sets are commonly used in residential and commercial buildings to connect radiators to central heating systems. These installations require precision in ensuring tight, leak-free connections between radiators and supply lines. Installers typically work with copper or multilayer piping such as ALPEX, where secure compression fittings are essential for long-term reliability.

This valve set is suitable for systems using standard 1/2 inch internal thread connections. The corner design allows for directional changes in the piping layout, accommodating space constraints and optimising flow direction. The integrated thermostatic function enables individual temperature control per radiator, supporting energy efficiency and comfort in heating systems.

The material specification, nickel-plated brass CW617N, ensures good corrosion resistance and mechanical strength. The connection size of 1/2 inch is compatible with standard radiators and piping. The included compression fittings support both copper and multilayer piping, ensuring flexibility in installation choices. These parameters are critical for correct sizing and system integration.Installation and connection Begin by verifying the radiator has a 1/2 inch internal thread. Apply a small amount of pipe sealant if required, then screw the M-valve into place. Connect the copper or multilayer pipe using the provided compression fittings, ensuring the correct torque is applied. For IVAR.TA fittings, apply 20–35 Nm torque; for IVAR.TR fittings, use 35–45 Nm. Check all connections for tightness and signs of leakage after installation. A common mistake is under-tightening the compression fittings, which can lead to leaks over time. Always ensure the piping is aligned correctly to avoid stress on the valve body.Compatibility and accessories This M-valve set is compatible with radiators featuring 1/2 inch internal threads, such as those from KORADO, PURMO, and KORAD. It works with copper piping of 15 x 1 mm and multilayer ALPEX piping of 16 x 2 mm. No additional accessories are required for standard installation, as the set includes all necessary components for immediate use. Ensure the selected piping matches the specified dimensions for secure compression fitting.Technical background for designers This M-valve operates by combining a thermostatic head with a compression fitting system. The nickel-plated brass body provides good thermal conductivity and durability. The compression fittings allow for secure, leak-free connections to copper or multilayer piping. The corner design facilitates directional changes in the piping layout, making it ideal for tight spaces. The material properties of CW617N ensure long-term resistance to corrosion and mechanical wear. The valve's integration into the system depends on correct sizing and torque application during installation to maintain performance and longevity.Service and operation Regular inspection of the compression fittings is recommended to ensure no signs of leakage or wear. Clean the thermostatic head periodically to prevent dust accumulation that could affect temperature regulation. No scheduled maintenance is required beyond these checks. If leakage occurs, the fitting should be re-tightened or replaced. Ensure the system pressure remains within normal limits to avoid stress on the valve body.Frequently asked questions
