ESBE VTA322 (¾”) mixing valve 70.70.00

Anti-scald function in domestic hot water installations

The ESBE VTA322 mixing valve is a key component of domestic hot water systems, ensuring a safe water temperature directed to the outlets. Its primary function is protection against burns by controlling the temperature of the heated water supplying the installation.

The operating mechanism is based on automatic mixing of hot and cold water, maintaining the outlet temperature at a level that does not exceed the set value. In practice, this means that even with high temperatures in the storage tank (often above 60°C), the user receives water at a safe temperature.

Technical parameters and construction

The device is equipped with an external thread G3/4", which ensures a standard connection with most hydraulic installations. Catalog number 70.70.00 identifies the specific model from the VTA322 series.

The temperature regulation range is 35-60°C, allowing for adjustment to individual user needs and sanitary requirements. The lower limit of 35°C ensures thermal comfort, while the upper limit of 60°C protects against the risk of second and third-degree burns.

The valve's construction enables precise regulation of the mixing ratio, which translates to a stable temperature regardless of changes in pressure or flow within the installation.

Operational benefits and system optimization

The use of the ESBE VTA322 mixing valve allows for system optimization and reduction of operating costs. By controlling the temperature of the heated water directed from the tank to the outlets, the system operates more efficiently, consuming less energy to maintain optimal operating parameters.

The anti-scald mechanism reduces the risk of thermal damage to plumbing components and pipelines caused by excessive temperatures, which translates to a longer lifespan for the entire installation.

Compliance and compatibility

The VTA322 valve can be used with various heat sources - gas boilers, heat pumps, as well as solar collectors. The standard threaded connection enables easy installation without the need for additional adapters or specialized tools.

The device can be installed in both new systems and during the modernization of existing domestic hot water installations.
