Thermostatic mixing valve TVM-W DN20 003Z3145

Thermostatic mixing valve – precise temperature control

The thermostatic mixing valve TVM-W DN20 is a reliable solution for maintaining a constant water temperature at draw-off points. It is a direct-acting valve that ensures the delivery of water at the required temperature, making it an ideal choice for both installers and end-users. Its robust construction and high precision regulation guarantee comfort and safety.

The valve is designed for use in domestic hot water installations, both in individual draw-off points (e.g., bathrooms, sinks, showers) and their groups. It is particularly important to use it in places where high safety is required – hospitals, schools, or during thermodisinfection of the installation to prevent the development of Legionella bacteria. Built-in check valves further increase the safety and functionality of the system.

Construction and characteristic features

The TVM-W valve is characterized by a solid construction with a body made of DZR brass with an anti-scale coating, which ensures durability and corrosion resistance. Its compact size (DN 20) allows for easy installation even in limited spaces. The external thread facilitates connection to the existing installation. The Kvs value of 2.1 ensures optimal water flow while maintaining precise temperature regulation. The maximum differential pressure in the open position is 5 bar, and the pressure class of the device and flange is PN 10 – which guarantees safe operation under standard installation conditions.

The valve has a factory-set temperature of 50°C, which can be locked after adjustment. This gives the user confidence that the temperature will not be accidentally changed. In addition, the valve automatically cuts off the water supply if one of the supply streams (hot or cold) fails, which provides additional protection against scalding.

Application and benefits

• Precise temperature regulation: Maintains a constant water temperature regardless of changes in pressure and supply temperature.
• Safety: Protects against scalding, especially important in public facilities and during thermodisinfection.
• High reliability: Solid construction with DZR brass and an anti-scale coating ensures long-term use without failure.
• Versatility: Can be used in individual draw-off points or their groups.
• Built-in check valves: Increase safety and functionality by preventing backflow of water.
• Easy installation: External thread facilitates connection to the existing installation.
• Setting lock: Prevents accidental change of the set temperature by the user.
