Which component is equipped with a bypass as a manually operated regulating valve for manual control in case of automatic regulator failure?

• A. Bypass valve
• B. Unloading valve
• C. Make-up valve
• D. Gland seal regulating station

Answer: (A)

Think of it as having a manual escape route around the automatic regulator so you can keep control if the automatic system fails. The bypass valve is designed exactly for that—it provides a manually operated path to regulate flow or pressure when the automatic regulator isn’t working. Opening and adjusting this valve lets you take over control and stabilize the system until the automatic regulator can be repaired. The other components serve different functions—unloading valves manage turbine load, make-up valves handle boiler feedwater, and gland seal regulating stations control gland steam—none are intended as the manual bypass path around the regulator.
