Thermostatic mixing valve – comfort and safety in your heating system

This thermostatic mixing valve ATM 561 from AFRISO is a reliable solution for precise temperature control in domestic hot water and central heating systems. Its main function is to maintain a constant, set temperature, ensuring user comfort and safety, particularly important in homes with small children or elderly people. This valve is ideal for both DHW systems and underfloor heating systems, offering versatility and ease of installation.

Protection against scalding and Legionella

A key feature of the ATM 561 valve is its "anti-scald" function. In the event of a loss of cold water supply, the valve automatically blocks the flow of hot water, eliminating the risk of scalding. Additionally, it enables safe overheating of water in DHW tanks, which is effective in combating Legionella bacteria – without exposing users to danger.

Versatile application and easy installation

The ATM 561 valve is characterized by its versatility and can be used in various heating system configurations. Its compact design allows for installation in tight spaces, and the G1" (DN20) threaded connection ensures compatibility with most standard installations. It requires no maintenance and can be mounted in any position, making it easy to install and use.

Construction features and parameters

The valve is made of high-quality DZR brass, which guarantees its durability and corrosion resistance. It has a temperature adjustment range of 20°C to 43°C and a flow coefficient Kvs of 2.5 m³/h, ensuring optimal performance in various hydraulic conditions. Additional features include a dual setting scale, the ability to seal the cover protecting against accidental change of settings, and a hex key socket for easy adjustment. A Kvs value of 2.5 m³/h ensures adequate medium flow in the installation.
