Thermostatic mixing valve ATM 343 DN15, G 3/4 inch, temperature range 35-60 °C, Kvs 1.6 m3/h 1234310

Thermostatic mixing valve – precise temperature control and protection

The ATM 343 thermostatic mixing valve is a reliable solution for regulating domestic hot water temperature in home and industrial installations. Designed to work with washbasin, shower and central heating systems, it provides comfort and safety, protecting against scalding. Its versatility makes it suitable for both private and public utility facilities.

The ATM 343 valve allows maintaining a constant water temperature, even with fluctuations in pressure and supply water temperature. This makes it ideal for situations where precise temperature control is required, such as in kindergartens or hospitals. Additionally, the valve allows for safe overheating of water in DHW tanks, which prevents the development of Legionella bacteria without the risk of scalding users.

Construction and application

The valve is made of high-quality DZR brass, which guarantees its durability and corrosion resistance. It has a G3/4 inch external thread and a temperature adjustment range of 35°C to 60°C. The Kvs value of 1.6 m³/h provides adequate water flow for most standard applications. The valve design allows for installation in any position, making it easier to install in various conditions.

The "anti-scald" function is an important safety feature – in the event of a lack of cold water supply, the valve automatically blocks the flow of hot water, eliminating the risk of scalding. Additionally, a plastic cover protects against accidental temperature adjustment, and a window allows for quick control. The valve is adapted to work with clean water or water containing up to 50% glycol.

• Scald protection: The "anti-scald" function blocks the flow of hot water if cold water is not available.
• Precise regulation: Maintains a constant water temperature regardless of changes in pressure and supply temperature.
• Sanitary safety: Allows for safe overheating of water in DHW tanks, preventing the development of Legionella bacteria.
• Durability and reliability: Made of high-quality DZR brass resistant to corrosion.
• Versatility: Possibility of installation in any position and use with various types of faucets and heating systems (including underfloor heating).
• Ease of use: The knob with a clear scale makes it easy to set the desired temperature.
• Protection against accidental adjustment: A plastic cover protects against unauthorized adjustment of the knob.

This valve can also be used as an element of underfloor heating installation, replacing more complex control systems and reducing the investment and operating costs of the heating system.
