Depends on the system, and it's design. Most standard sprinkler systems are designed for a 30 gallon per minute rate for each sprinkler head. Standpipes and hose lines have other design criteria, as do deluge systems. They ALL take a LOT of water!
A sprinkler bell valve in a fire protection system controls the flow of water to sprinkler heads. It opens when the system detects a fire, allowing water to flow and extinguish the fire.
Some fire sprinkler systems have a valve for testing the water-flow alarm by allowing water to flow to the alarm, or through the alarm-sensing pipe, without activating any sprinklers in the rest of the system.
The heat of the fire causes sprinklers to trip, releasing nitrogen or some other gas held under pressure in the system through the sprinklers. This action activates a dry pipe valve within the sprinkler system which releases fire protection water which has been restrained within the system, through the sprinklers with the intention of dousing if not extinguishing the fire.

The cooling effectiveness of the chilled water system depends on the water flow. Thus the water flow rate, as well as the temperature of the water, need to be monitored and adjusted to provide the chilling effect.

A gate valve in a water main system controls the flow of water by opening or closing a gate inside the valve. It is used to stop or regulate the flow of water in the system.
The Navien flow sensor in the Navien water heater system detects the flow of water through the system. It helps the water heater regulate the temperature and ensure efficient operation by activating the heating elements only when water is flowing.
