When the critical temperature of 95°C is reached, cold domestic water is passed through the heat exchanger to cool the boiler. As soon as the temperature drops, the valve closes automatically. The discharge safety device complies with the requirements of the DIN 3440 and DIN 4751 standards for solid fuel boilers with outputs up to 100 kW.\u003c\/p\u003e\n\n\u003ch2\u003e \u003cstrong\u003eProduct features:\u003c\/strong\u003e\n\u003c\/h2\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e\n\n \u003cstrong\u003eEffective overheating protection:\u003c\/strong\u003e Protects boilers by automatically opening at temperatures above 95°C.\u003c\/li\u003e\n\n\u003cli\u003e\n\n \u003cstrong\u003eReliable reset:\u003c\/strong\u003e Valve closes automatically when the temperature returns to the safe range.\u003c\/li\u003e\n\n\u003cli\u003e\n\n \u003cstrong\u003eHigh-quality materials:\u003c\/strong\u003e housing and control spindle made of brass, seals made of robust EPDM, spring made of stainless steel.\u003c\/li\u003e\n\n\u003cli\u003e\n\n \u003cstrong\u003eEasy installation:\u003c\/strong\u003e With 3\/4\" female thread connections and an immersion sleeve with 1\/2\" male thread for the temperature sensor.\u003c\/li\u003e\n\n\u003cli\u003e \n\u003cstrong\u003eCompliant with standards:\u003c\/strong\u003e Complies with DIN 3440 and DIN 4751 as well as the ISPESL standard (Chapter R 3C. 1.
