The master SOPV controls which two valves?

• A. Hycheck and power check
• B. Isolation valve and relief valve
• C. Check valve and shutoff valve
• D. Pressure relief valve and bleed valve

Answer: (A)

The master SOPV is the control that governs one-way flow in the hydraulic control path, specifically handling two check-type valves. Those two valves are the hycheck and the power check. The hycheck allows fluid to flow in the operating direction and prevents backflow, while the power check provides one-way flow in the power circuit and ensures pressure can’t reverse when the system is de-energized. Together, they manage how hydraulic pressure is delivered to and held in the actuating lines. Other valve types (isolation, relief, bleed, etc.) have different roles and aren’t the pair controlled by the master SOPV in this setup.
