Caleffi double thermal safety valve ½" opens at 90-100°C

Double thermal safety valve with built-in refill for wood-burning stoves and boilers with water jacket
The double thermal relief valve is used as a safety device in heating systems with solid fuel heat generators. The device combines a thermal relief valve and a filling valve in a single unit, which are activated simultaneously with positive safety when controlled by a remote sensor.
When the valve is activated, the built-in refill system adjusts the water circulation during the combustion of the remaining fuel, thereby protecting your boiler and heating system.
