What is a potential issue if the dropout voltage on the safety valve is high?

A high dropout voltage on the safety valve indicates that the valve may not be able to maintain proper closure when it should. This condition can lead to safety concerns, as the safety valve is crucial for controlling the gas flow in the system. If the dropout voltage is higher than normal, it may signify that the valve is not performing as required, which compromises its ability to shut off the gas supply when necessary. Therefore, a thorough check is warranted, and in many cases, replacement of the safety valve becomes necessary to ensure safe and reliable operation of the equipment.

In contrast, a functional thermocouple wouldn’t be indicative of high dropout voltage, as the thermocouple's role is to ensure that the gas valve opens under safe conditions. Similarly, adequate gas supply and a non-functioning thermostat do not directly correlate to high dropout voltage either. Inadequate or fluctuating voltage rather points directly to issues with the safety valve itself.
