Thermostatic mixing valve ATM 331 DN20 RP 3/4 inch temperature range 20-43 °C, Kvs 1.6 m3/h 1233110

Thermostatic mixing valve – protection and comfort in your home

The ATM 331 thermostatic mixing valve is a reliable solution for precise domestic hot water temperature control. It is ideal for both home installations and professional systems where safety and comfort are a priority. Designed for mounting on washbasin and shower batteries, it provides protection against scalding and a quick response to changes in water pressure and temperature.

Functionality and application

The ATM 331 valve is not only protection against burns. Its applications also include:

• Safe water overheating: Allows heating water in DHW tanks to a temperature that kills Legionella bacteria, without the risk of scalding users.
• Underfloor heating: Can replace complex and costly control systems in underfloor heating systems.
• Versatility: Designed to work with clean water or water containing up to 50% glycol, which expands its range of applications.
• Easy installation: Thanks to the internal Rp 3/4 inch thread, the valve is easy to install and disassemble.

The valve is characterized by high efficiency – the Kvs flow rate is 1.6 m³/h, which guarantees an adequate water flow even with high demand. The temperature regulation range from 20°C to 43°C allows for precise adjustment of the water temperature to individual preferences.

Construction and distinguishing features

The ATM 331 valve is distinguished by a solid construction made of high-quality DZR brass, which ensures its durability and corrosion resistance. Additional features that facilitate use include:

• Dual scale: Allows easy reading of the set temperature.
• Possibility of sealing the cover: Protects against accidental change of temperature setting.
• Convenient knob: Provides precise temperature control.
• Allen key socket: Facilitates turning the knob in case of regulation problems.
• Raw surface finish: Allows the valve to be adapted to the aesthetics of the installation.

Thanks to its well-thought-out design, the valve requires no maintenance and can be mounted in any position, making it easy to install even in hard-to-reach places.
