Thermal safety valve

Product detailed description

Cooling loop control valve – WATTS STS20 S - 93°C- 3/4"

The Watts STS thermostatic valve is most commonly used to protect against water overheating in biomass boilers. This simple valve, which does not require external power, opens when the temperature at the location of its sensor rises above the factory-set value (e.g. 95°C), allowing cold water to flow through the heat exchanger (e.g. coil), quickly and effectively reducing the temperature in the boiler.
