What is the function of a pressure governor in firefighting?

The function of a pressure governor in firefighting is to maintain consistent pump pressure. This device automatically adjusts the throttle of the engine to ensure that the desired pressure level is achieved and maintained during operation. By continually monitoring and regulating the pressure, the pressure governor helps to deliver a stable water flow to the firefighting apparatus, allowing firefighters to effectively manage the water supply during operations. This is crucial for ensuring that hoses and nozzles operate within their designed pressure ranges, which enhances safety and efficiency while responding to fire incidents.

Maintaining consistent pump pressure also improves the accuracy of water distribution and helps prevent fluctuations that could compromise firefighting efforts.
