What is the role of a pressuretrol in a steam boiler?

The role of a pressuretrol in a steam boiler is to control the steam pressure. This device is crucial for maintaining safe and efficient operation within the boiler system. The pressuretrol monitors the pressure of the steam produced and has the ability to activate the boiler’s burner or shut it off when the pressure reaches pre-set levels.

When steam pressure rises beyond the desired setting, the pressuretrol will trigger a response, typically by signaling the burner to turn off, thus preventing overpressure conditions that could lead to safety hazards. Conversely, if the pressure drops below a certain threshold, the pressuretrol will activate the burner to restore the pressure back to the required level.

This critical function ensures that the steam system operates reliably within designated parameters, enhancing safety and efficiency in steam generation.
