How would the illustrated valve respond to a complete loss of charge from the remote bulb-to-control diaphragm power element if the valve is used as a temperature control valve for a steam-heated heavy fuel oil service heater? Illustration GS-0045
A
The valve would fail in the fully closed position, resulting in a low fuel oil temperature alarm.
B
The valve would fail in the fully open position, resulting in a high fuel oil temperature alarm.
C
It is not possible to predict how the valve will respond to a complete loss of charge from the power element.
D
The valve would fail in the exact position it was in before the power element lost its complete charge, resulting in a fluctuation in fuel oil temperature as demand changes.
