What is the function of the control valve in a sprinkler system?

• A. Indicating Valve to Control Water Supply to Sprinklers.
• B. Check Valve to Prevent Backflow.
• C. Drain Valve for System Drainage.
• D. Pump Controller Switch.

Answer: (A)

The control valve’s job is to regulate the water supply to the sprinkler system, allowing the system to be shut off for service or in an emergency. In many residential setups this valve is an indicating valve, which also provides a visible status and may include a tamper switch to alert the fire alarm if someone changes it. This is different from a backflow prevention device (check valve) that stops water from flowing backward into the supply, a drain valve used to drain the system, or a pump controller switch that starts or stops the fire pump. So, its function is to control the water supply to the sprinklers.
