| 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? Refer to 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. |
