A pressure regulator in a boiler primarily serves to manage the pressure within the system to ensure safe and efficient operation. Maintaining a constant pressure is crucial for the boiler's performance, allowing it to operate optimally and preventing damage from pressure fluctuations. Adjusting the flow rate based on demand is also a critical function, as it helps to match the output of the boiler with the needs of the system while optimizing fuel consumption.

Compensating for load variations is important as well, as the pressure regulator adjusts the system to accommodate changes in demand for steam or hot water, ensuring reliable operation under varying conditions.

However, controlling water quality is not a function of the pressure regulator. Water quality is managed through other means, such as chemical treatment, filtration, and monitoring systems which address aspects like pH, dissolved solids, and contaminants rather than pressure control. Thus, since water quality management does not relate to the function of a pressure regulator, this is why it is the correct choice.
