The use of thermal relief valves is obligatory in all open tank systems using solid, non-pulverised fuel fired boilers. The heat sensitive element, immersed in the boiler water, expands as temperature increases thus causing the valve plug to open when the temperature reaches the set value. The valve is furnished with 2 heat sensitive elements; in the event of failure of one element, the other will assure that the valve is operational.
