Aquastrom VT Thermal circulation valve with press connection
DN 15, 18 mm, with thermal insulation and thermometer

Aquastrom VT thermal circulation valve with presetting of the control temperature for thermal control and with presetting of the residual volume flow for hydronic balancing in circulation pipes according to DVGW work sheet W551/W553.

Thermal control:
Recommended control range: 55 °C to 60 °C (max. control range: 50 °C to 65 °C, control accuracy ±1 °C)

For a preset temperature (e.g. 57 °C), the valve reduces the volume flow from this temperature to a residual value, which is to be determined from the calculation regulations according to the DVGW work sheet and can be set accordingly on the valve. The valve also supports automatic thermal disinfection. Approx. 6 °C above the set temperature, the volume flow increases again and is reduced to the residual volume flow again from approx. 16 °C above the set temperature. The reduction back to the residual volume flow ensures that the downstream system sections are also supplied with a disinfection volume flow due to the restored hydronic balance. The valve thus optimally supports the thermal disinfection of the circulation system. At the end of the disinfection phase, the valve returns to its initial position.

Incl. insulation complying with fire protection class B1 and thermometer.
