The ESBE thermostatic mixing valves series VTA320 offer high flow capacity and good functionality for universal applications, such as domestic hot water with or without HWC (hot water circulation) and smaller underfloor heating circuits.
Series VTA320 are the number one choice for domestic hot water systems requiring an in-line scald safe* function and where further temperature control devices have been installed at the water taps. These series of valves are also suitable for domestic hot water installations equipped with HWC (hot water circulation).
Series VTA320 are suitable for under floor heating applications, as long as special attention is paid to temperature range and flow requirements.
Asymmetrical flow pattern. Scald safe*.
