What role do pressure-reducing valves play in fire pump systems, and how are they applied?

Pressure-reducing valves (PRVs) are essential components in fire pump systems, particularly in high-rise buildings or situations where the pressure needs to be regulated. These valves reduce the pressure of the water supplied by the fire pump to a manageable level suitable for the fire protection system's components, such as sprinklers, standpipes, or hoses. PRVs ensure that the pressure does not exceed the design limits of the system, preventing damage to equipment and minimizing the risk of water wastage or leakage. Proper application of PRVs involves considering factors such as the desired outlet pressure, flow rate, and system layout to select the appropriate valve type and size.
