Sets vekoluxivar, AVK vekoluxivar

This category includes complete Vekoluxivar and AVK Vekoluxivar sets for thermostatic radiator valves in two-pipe heating systems. The kits are designed for installation on copper or multi-layer ALPEX pipes and include all necessary components for connecting the thermostatic head to the valve body. They are suitable for use with valve bodies featuring an M 30 x 1.5 thread and are available in straight or corner configurations to suit different pipe layouts and radiator positions.

The sets are manufactured from nickel-plated brass (CW617N) and are rated for a maximum operating temperature of +120 °C and a pressure rating of PN 10. They are compatible with a range of valve bodies from brands such as Kermi, Cosmonova, Buderus, Korado, Purmo, and Korad. The kits include clamping screws for secure pipe connections and are available in different configurations for 1/2" internal or 3/4" external thread valve bodies.

How to choose

• Select the correct configuration (straight or corner) based on the pipe layout and radiator position.
• Ensure compatibility with the valve body by checking for an M 30 x 1.5 thread on the valve insert.
• Choose the appropriate connection type (1/2" internal or 3/4" external thread) to match the valve body and system design.
• Verify the pipe material (copper Ø 15 x 1 mm or ALPEX Ø 16 x 2 mm) to ensure the correct clamping screw is included in the set.
