Thermal protection of a solid fuel boiler 5067.20.000

Thermal protection 5067 of the installation is used to protect solid fuel boilers in heating installations equipped with thermostatic valves in accordance with the Polish Standard PN-EN303-5. It is especially recommended for boilers that are not equipped with a cooling exchanger.
The thermal protection valve 5067 consists of the following parts: a check valve, a pressure reducer, a thermally controlled filling and discharge valve, a temperature sensor with a capillary.
The pressure reducing valve is connected to the water mains, the output of the thermally controlled filling valve is connected to the boiler return line as shown in the adjacent figure. An ejection valve is connected to the power supply line and hot water from the heating system flows out, thus cooling the boiler
