Thermal safety valve
VST200
- Excellent safety for solid fuel boilers.
- Two independant temperature sensors.
- Metal hose coating of the capillary tubes.
The series VST200 prevents excess temperatures in solid fuel fired boilers. Heating capacities of up to a maximum of 100 kW are allowed for these systems. The thermal safety valve is a pressure-relieved single-seated valve that opens in case of escalating temperature. Install the thermal safety valve preferably in the cold water inlet of the safety heat exchanger.
