What valve permits the sprinkler valve for the magazine sprinkler system to be secured from other stations?

• A. Hydraulically operated control valve
• B. Manual valve
• C. Check valve
• D. Gate valve

Answer: (A)

Remote actuation is the key idea here. The sprinkler valve for the magazine sprinkler system needs to be able to be secured from a different station, so you can isolate the system without exposing yourself to heat, smoke, or danger at the valve location. A hydraulically operated control valve is designed to be actuated from a remote station through a hydraulic control line, letting you shut or secure the valve from afar. This remote capability is what makes it the right choice for securing the magazine sprinkler valve from other stations. A manual valve, by contrast, requires you to be at the valve to operate it, so it can’t be secured from a distant location. A check valve’s job is to prevent backflow, not to control the sprinkler valve remotely. A gate valve is a type of shutoff, but unless it’s specifically configured for remote actuation, it doesn’t provide remote control from other stations in the magazine sprinkler setup.
