Remote operation of a pilot-operated valve __________________.

Remote operation of a pilot-operated valve __________________.

• A. allows the relief to operate at two pressure levels
• B. requires use of a small DCV
• C. allows the machine operator to easily change pressure settings
• D. none of the above

Answer: (C)

Remote operation means the pressure setting for the pilot-operated valve can be adjusted from a distance, using a remote control signal or pilot line rather than having to reach the valve itself. This lets the machine operator change the set pressure quickly and safely from a control panel or remote station, which is why the best choice says it enables easy adjustment of pressure settings. The idea of two pressure levels isn’t intrinsic to remote operation of a pilot-operated valve, and requiring a small DCV isn’t a defining feature either—the control method can vary and isn’t mandated by the concept.
