During an annual inspection, what is the primary focus regarding control valves?

The primary focus during an annual inspection of control valves is on their physical condition and operation. This is crucial because control valves play a vital role in the functionality of a fire protection system. Inspectors need to ensure that these valves are not only in good physical condition—checking for signs of corrosion, leaks, or damage—but also that they are operating correctly. This includes verifying that they can be opened and closed as intended and that there are no obstructions preventing their normal operation.

While aspects like the color of the valve, its location, and the type of valve used are important considerations in broader contexts, they do not directly relate to the operational readiness and reliability of the fire protection system. The primary concern during inspections is to ensure that the equipment will perform effectively in the event of a fire, and assessing the physical condition and operation of the valves is key to achieving this goal.
