In gravity dump systems, the dump valve may be closed manually or by what device?

• A. Hydraulics
• B. Electronic Device
• C. Pneumatic Cylinder
• D. Electric Motor

Answer: (B)

In gravity dump systems, the dump valve can be closed automatically by an electronic control that drives the valve opener/closer. The best answer is an electronic device because electrical controls (like a solenoid or electronic actuator) provide reliable, rapid closure triggered by the system’s timing or safety interlocks, coordinating with the dump cycle without manual effort. While hydraulic, pneumatic, or electric motor actuators could close a valve, the description calling for an electronic device specifically points to an electrical control element that manages the shutdown automatically.
