The SOPV is a device described as which type of valve?

• A. Check Valve
• B. Solenoid Operated Pilot Valve
• C. Gate Valve
• D. Manual Valve

Answer: (B)

The device is a Solenoid Operated Pilot Valve, meaning it uses an electric coil to move a plunger that opens or closes a small pilot passage. This pilot action controls pressure to a larger valve or actuator, enabling automatic, remote, or interlocked operation. It’s different from a manual valve (which you turn by hand), a gate valve (which uses a gate that slides to block flow), or a check valve (which prevents backflow). The key idea is that the solenoid provides the control signal for the pilot valve, which then governs the main flow path in the system.
