Thermostatic mixing valve ESBE VTA522 20-43°C G1 1/4 + R1 20-3.4 31621000

Thermostatic mixing valve – precise temperature control

This ESBE VTA522 thermostatic mixing valve is a reliable solution for regulating temperature in domestic hot water systems and heating systems. Designed for installation both at draw-off points and on the supply line, it provides comfort and safety, protecting against scalding. This valve is particularly useful in installations with a domestic hot water circulation system or where additional protection against excessively high temperatures is required.

The VTA522 valve is characterized by its high flow rate and versatile application. Thanks to precise temperature control in the range of 20-43°C, it allows you to adjust the operating parameters of the installation to individual needs. Supplied with two check valves (for hot and cold water) simplifies installation and ensures proper system operation.

Construction and application

The VTA522 valve has an external thread size of 1 inch, making it easy to integrate with existing installations. Its asymmetrical flow characteristic ensures a stable output temperature even with fluctuating supply pressure. It can be used in various configurations – from simple domestic hot water installations to more complex systems with underfloor heating or solar collectors. Made of dezincification-resistant brass, it guarantees durability and reliable operation for a long time.

This valve finds application in:

• Domestic hot water installations with or without a circulation system
• Underfloor heating systems (taking into account the requirements regarding temperature range and flow)
• Solar installations
• District heating system substations
• Systems with heat pumps and domestic hot water tanks
