What is the purpose of the HYD SOV?

• A. Interrupts flow between the reservoir and the engine-driven pump
• B. Regulates reservoir temperature
• C. Controls anti-skid functions
• D. Provides electrical power to pumps

Answer: (A)

A HYD SOV is a hydraulic shut-off valve that isolates the hydraulic system by interrupting flow between the reservoir and the engine-driven pump. This valve lets maintenance or a fault isolation scenario quickly stop fluid movement into the pump, preventing unwanted pump operation or cross-contamination. When commanded, it closes to block flow; when not commanded, flow can continue to the pump as needed. It’s not responsible for regulating reservoir temperature, anti-skid functions, or supplying electrical power to pumps—the latter comes from the electrical power system, and the others are handled by separate subsystems.
