A lever safety valve consists of a valve body that has flange fixed to the steam boiler. The valve seat made of bronze is screwed to the body. The valve seat contains the valve which is also made up of bronze. Since the valve seat and valve is made up of same material, the rusting is prevented. The strut transmits the thrust on the valve.

The refractory acts as both an insulating material and a protective layer for preventing the external walls of the boiler from getting damage. However, the problem with using refractory material in the furnace walls is that due to high temperature and pressure the material tends to come out of its position, especially from vertical walls.
