What feature does an indicating type valve provide?

• A. Visual indication of valve position
• B. Automatic leak detection
• C. Sound when opened
• D. Locking mechanism

Answer: (A)

An indicating type valve is designed to give a visible readout of its position from the outside. This lets a person quickly confirm whether the valve is open or closed without having to inspect the stem or operate the valve. The visual indicator—often a window, dial, or colored marker—shows the status so inspectors and operators can verify that the fire protection system is correct and ready for water flow. Automatic leak detection, an audible sound when the valve is opened, and a locking mechanism are separate features not defined by the indicating type valve’s purpose. The key point is the clear, at-a-glance visual indication of valve position.
