Which devices control water flow in sprinkler systems?

• A. Gauges
• B. Valves
• C. Alarms
• D. Sprinkler Heads

Answer: (B)

Valves are the devices that control water flow in sprinkler systems. They physically start, stop, and segment the water supply, which is essential for both fire response and maintenance. The main shutoff valve can stop water to the entire system, while sectional valves isolate parts of the network so a problem in one area doesn’t affect the rest. Test and drain valves enable testing and draining without draining the whole system. Gauges, alarms, and sprinkler heads have important roles—gauges monitor pressure, alarms signal when water moves, and sprinkler heads release water when heat is detected—but they do not regulate or route the flow.
