Steam and Condensate - A basic overview of a steam system

The stop or crown Valve isolates the boiler and its steam pressure from the process or plant. If steam is pressurised, it will occupy less space. Steam boilers are usually operated under pressure, so that more steam can be produced by a smaller boiler and transferred to the point of use using small bore pipework.
