The thermostatic mixing valve ESBE series VTA 320 is a suitable component for universal use in domestic hot water installations equipped with HWC (hot water circulation). It is also suitable for smaller floor heating circuits (up to 50m2) if you want to pay special attention to the temperature and flow range.
Usage
- Distribution of fresh/drinking water
- Water distribution with antifreeze (≤ 50% glycol mixture)
- Closed water system
