For the gland seal regulator shown in the illustration, an increase in gland seal pressure will result in ________. Illustration SE-0019

Correct Answer: Option A — piston 'F" moving upward to shut the makeup steam valve "B" and open the exhaust valve "E"

Elevated seal pressure expands the sensing bellows, forcing piston 'F' upward. This mechanical action closes the makeup steam valve 'B' while simultaneously opening the exhaust valve 'E' to vent excess pressure, stabilizing the header.
