The 000024 26 valve also supports automatic thermal disinfection. 000025 26 Approx. 6 °C above the set temperature, the volume 000026 26 flow increases again and is reduced to the residual 000027 26 volume flow again from approx. 16 °C above the set 000028 26 temperature. The reduction back to the residual 000029 26 volume flow ensures that the downstream system 000030 26 sections are also supplied with a disinfection volume 000031 26 flow due to the restored hydronic balance. The valve 000032 26 thus optimally supports the thermal disinfection of 000033 26 the circulation system. At the end of the 000034 26 disinfection phase, the valve returns to its initial 000035 26 position. 000036 26 000037 26 Incl. insulation complying with fire protection class 000038 26 B1 and thermometer. 000039 26 000040 26 DVGW, SVGW, KIWA, VA, WRAS and WaterMark certified. 000041 26 000042 26 Material: Bronze 000043 26 000044 26 Nennweite: DN 20 000045 26 Anschluss: External thread 000046 26 000047 26 Art.-Nr.: 4206706 000048 26 EAN-Code: 4026755332261 000049 26 Hersteller: OVENTROP GmbH & Co.
