The main control valve for a sprinkler system should always be what type?

• A. Indicating type valve
• B. Gate valve
• C. Globe valve
• D. Ball valve

Answer: (A)

Having a clear indication of the valve’s position on the main control valve is essential. An indicating type valve provides a built-in indicator that shows whether the valve is open or closed, so responders and maintenance personnel can instantly verify the system’s status without guessing or relying on lock positions or handle orientation. This visibility is crucial for safe operation, testing, and compliance, ensuring the sprinkler system can be reliably isolated for maintenance or verified as ready for service during an emergency. Other valve styles can function, but they don’t inherently give a reliable, immediate read of the valve’s status, which can lead to confusion or unsafe assumptions in critical moments.
