Thermostatic mixing valve ATM 333 DN20 RP 3/4 inch temperature range 35-60 °C, Kvs 1.6 m3/h 1233310

Thermostatic mixing valve – scald protection and precise regulation

The ATM 333 thermostatic mixing valve is a reliable solution for regulating domestic hot water temperature, providing comfort and safety in every home. Designed for installation between a DHW tank and draw-off points, it protects against scalding, particularly important for children and the elderly. Thanks to its quick response to changes in water pressure and temperature, it guarantees a stable temperature even with large fluctuations in the installation. The valve is ideal for both single-family and multi-family buildings.

Construction and application

The ATM 333 valve is characterized by a solid construction made of DZR brass, which ensures its durability and corrosion resistance. It is equipped with an internal Rp 3/4 inch thread and a temperature adjustment range of 35 to 60°C, allowing for precise adjustment of the water temperature to individual needs. The Kvs value of 1.6 m³/h ensures adequate water flow, even with high demand. The valve is used in DHW installations, and can also be used in central heating systems, e.g. underfloor heating as an element for regulating the return temperature. The "anti-scald" function blocks the flow of hot water if cold water is not available – an additional safety feature for users.

Key features and benefits

• Scald protection: The valve automatically limits the water temperature, eliminating the risk of scalding, especially important for families with children or the elderly.
• Stable temperature: Quick reaction to changes in pressure and temperature ensures a constant water temperature regardless of conditions in the installation.
• Durable construction: Made of high-quality DZR brass guarantees long-term use and corrosion resistance.
• Wide adjustment range: The temperature adjustment range of 35-60°C allows you to adjust the temperature to individual user preferences.
• Possibility of sealing: The valve cover can be sealed, which prevents accidental changes to the settings by unauthorized persons.
• Convenient operation: A large knob with a clear setting indicator makes it easy to precisely set the desired water temperature.
• No maintenance required: The valve does not require regular maintenance, which translates into saving time and operating costs.
• Versatility: Can be used with clean water or water containing up to 50% glycol, expanding the range of valve applications.
