Thermostatic flow limitation valve
VTF320
- Simple installation and usage
- Responsive, quick and accurate
- Flow limitation with 55°C
- System optimization
- Exploitation cost reduction
- Energy savings
Thermostatic flow limitation valves applicable where flow limitation and temperature safety is required. Series VTF300 are designed for potable hot water circulation systems to secure the right PHW-C temperature. The valves allow to optimize the system, keep it efficient and decries the exploitation cost.
The VTF320 closes the flow of the potable water circulation when the desired temperature is reached. This function allows to optimize the PHW system by shutting off zones which are already heated, and/or continue to heat zones which are below desired temperature. Thermostatic flow limitation valves applicable where flow limitation and temperature safety is required.
