Abstract
A gas valve assembly may include an electronic valve controller secured relative to a valve body. The electronic controller may be configured to count each operational cycle of the gas valve and maintain a cumulative count of the number of operational cycles experienced by the gas valve in a memory, such as a non-volatile memory. In some cases, the non-volatile memory may also store one or more operational cycle threshold values that may be retrieved and compared to the cumulative count of the number of operational cycles experienced by the gas valve. In some instances, where the cumulative count of the number of operational cycles experienced by the gas valve meets and/or exceeds the threshold number of operational cycles, the gas valve may be prevented from opening.
