Which valve is the AFFF flow control valve known as, commonly called powercheck?

• A. AFFF Flow Control Valve (powercheck)
• B. Seawater Flow Control Valve (hycheck valve)
• C. Solenoid Operated Pilot Valves (electronically activate the AFFF)
• D. Eductor

Answer: (A)

The function being tested is metering the foam concentrate in the AFFF system. The valve that does this specific job is the AFFF Flow Control Valve, and it’s commonly called powercheck in Navy terminology. This nickname comes from its role in throttling the concentrate flow and preventing backflow, ensuring the foam mix is the correct proportion when the system is activated. Other options refer to different components: a seawater flow control valve would manage seawater supply, solenoid operated pilot valves control electrical actuation of the AFFF system, and an eductor uses a Venturi effect to draw concentrate into water. So the valve that’s known as powercheck is the AFFF Flow Control Valve.
