What is the function of a pressure-reducing valve in a sprinkler system?

The function of a pressure-reducing valve in a sprinkler system is to secure a consistent and safe water pressure throughout the system. This device is critical for ensuring that the water pressure does not exceed the recommended levels, which can prevent damage to the sprinkler heads and the piping system. By regulating the pressure, these valves help maintain optimal operation of the system, promoting effective water distribution when the sprinklers activate. This consistent pressure allows for better coverage and efficiency in extinguishing fires, enhancing the overall effectiveness of fire suppression efforts.
