ASME Boiler and Pressure Vessel Code - Stop valves

Boiler master control should provide two kinds of control mode, one is the common master mode and the other one is the individual boiler master mode.. 1. Common master control: When the boiler is operated in parallel with the other boiler units, this control mode must be selected. In this mode the boiler is controlled so as to maintain the common high-pressure steam header pressure.

300 PSI), whereas Industrial applications tend to have high-pressure systems (over 600 PSI). System pressure determines which water treatment chemicals are appropriate for oxygen scavenging. For example, in a high-pressure system, the feedwater quality needs to be very pure and free of dissolved solids to avoid causing scale.
