In a boiler system, what is the role of control valves in relation to steam pressure?

Control valves play a crucial role in a boiler system by regulating and maintaining desired pressure levels within the system. Their primary function is to adjust the flow of steam or water based on the feedback from pressure sensors to ensure that the pressure remains stable and within specified limits. By doing so, control valves help to optimize the efficiency of the boiler operation, prevent overpressure conditions that could lead to safety hazards, and ensure that the steam or water delivered meets the needs of the system or processes dependent on it.

Maintaining the proper steam pressure is vital, as it affects the performance and efficiency of connected equipment. Should the pressure rise above safe operating levels, control valves will modulate the flow to alleviate excess pressure, thereby safeguarding the integrity of the system and maintaining consistent operational conditions. This regulatory function is essential for both safety and efficiency in boiler applications.
