Thermostatic mixing valve

VTA330, VTA530

Series VTA330 is primarily designed to provide a highly accurate temperature regulation in point-of-use positions for domestic hot water, at taps or showers where no further temperature-control fittings have been installed. Series VTA530 is primarily designed to provide an accurate in-line temperature regulation of the domestic hot water in high flow applications, according to standards EN15092 or EN1111/NF079, where further temperature control fittings have been installed at taps or showers.
  • Excellent accuracy of regulation.
  • Anti-scald and anti-legionella protection.
  • Quick reaction time.
  • Performing under varying pressure conditions.
