For the gland seal regulator shown in the illustration, an increase in gland seal pressure will result in _ . Illustration SE-0019
AI Explanation
The correct answer is D) piston "F" moving upward to shut the makeup steam valve "B" and open the exhaust valve "E".
Explanation:
An increase in gland seal pressure will cause piston "F" to move upward, which will shut the makeup steam valve "B" and open the exhaust valve "E". This allows the excess pressure to be released through the exhaust valve, rather than admitting more makeup steam through valve "B". The other answer choices describe the opposite movement of the piston, which would not be the correct response to an increase in gland seal pressure.
