Steam Heating System Controls & Gauges: Photo Guide

Low pressure steam boilers still require a pressure/temperature safety relief valve. A pressure relief valve is a spring-loaded device that will open to spill excess pressure (and temperature) in the form of water, steam, or a mix of the two, at a pre-determined pressure in order to protect the heating appliance from damage, or worse, a dangerous BLEVE explosion.
