What is the purpose of a makeup control valve?

The purpose of a makeup control valve is to maintain a constant water level within a steam system or boiler. This valve automatically regulates the flow of water into the system to compensate for water loss due to steam generation, blowdown, or leakage. By ensuring that the water level remains stable, the makeup control valve helps to prevent issues such as overheating or damage to the boiler caused by low water levels, which could lead to inadequate cooling of the boiler and potentially dangerous operational conditions.

Maintaining the appropriate water level is critical for the safe and efficient operation of steam systems, as fluctuations in water levels can impact overall system performance and safety. Thus, the makeup control valve plays a crucial role in ensuring operational reliability and efficiency in a boiler system.
