Overheat Safety Valve Pressurised Systems

An overheat safety valve provides protection to a boiler stove that has been designed for installation onto pressurised systems.

How does this work?
The boiler stove will have a copper finned coil inside the boiler jacket, this is called a quench coil.  The over heat valve has a sensor probe which is fitted into an immersion pocket on the boiler stove, if the heat sink radiator does not get rid of the excess heat in an emergency (temperatures in excess of 97 deg C) then the valve will release cold mains water through the quench coil which will cool down the boiler temperature.
