Load valve

VTC400

  • accurate control of the return water temperature
  • high kvs value
  • available fixed and adjustable temperature setting
  • wide range of temperatures

The ESBE thermic valves series VTC400 are designed for applications with boilers, which require return temperature control. Maintaining a high and stable return temperature means a higher level of boiler efficiency, reduced tarring and increased life span of boiler.
