How pressuretrol works in steam boiler - Boilersinfo

24/6/2017 · The pressuretrol starts and shutdown the boiler according to adjusted pressure it also controls its operating range. For example, an average operating range of a steam boiler may be 240 to 250 psi. When the steam pressure in the boiler drops 10 psi, the boiler will start up automatically. When the pressure reaches to 250 psi, it will shutdown
