Thermostatic mixing valve
VTS550
- High temperature resilience.
- Anti-scald and anti-legionella protection.
- Accuracy of regulation.
- Suitable for HWC (hot water circulation).
The series VTS550 for domestic hot water distribution connected to solar heating systems, where the high water temperatures require extra durable components. VTS550 has symmetrical flow pattern. These series of valves are also suitable for domestic hot water installations equipped with HWC (hot water circulation).
