Proper Pressure Settings for Residential Steam Boiler

The pressuretrol serves to turn the boiler off it the pressure rises above the cutoff setting -- which in your case should be 1 on the diff and 1 on the main, or even better 0.7 on the main. Reset it to where it was! What it doesn't do is raise the pressure in the boiler. The fact that your 0 to 5 psi gauge doesn't move, and the pressuretrol doesn't turn the boiler off, and the system heats well, simply indicates that …

Plant Engineering | Set-up and design for a steam-pressure

Dec 13, 2013· Steam enters the PRV station at a higher pressure than what is required for downstream applications, and the station reduces the pressure to the desired level before delivering steam to those applications. Within a steam PRV station (See Figure 1), the controlling valve—which reduces the steam pressure—is typically a pneumatic control valve.
