Which device converts electrical signals to mechanical energy?

Which device converts electrical signals to mechanical energy?

• A. Powertrol Valve
• B. Master SOPV
• C. Hycheck
• D. Station control

Answer: (B)

Electric signals are turned into motion when a valve is driven by a solenoid. The Master SOPV, or Master Solenoid-Operated Hydraulic Valve, is designed to receive electrical control signals and actuate a hydraulic valve spool, converting electrical energy into hydraulic pressure and mechanical movement. This direct energy transformation is what lets the control system move hydraulic actuators and valves throughout the ship. The Hycheck is a hydraulic check valve that blocks reverse flow and doesn’t respond to electrical signals. Station control is the command interface, not a device that converts electrical energy into motion. Powertrol Valve may be part of hydraulic control, but it isn’t the component whose primary job is converting electrical energy to mechanical energy like the Master SOPV.
