Abstract
A gas valve assembly may include a valve body with one or more valves movable between an opened position and a closed position, one or more valve actuators configured to operate the valves, and one or more pressure sensors to sense a pressure within a fluid path of the valve assembly. A valve controller may receive a measure related to a sensed pressure from the one or more pressure sensor(s). The valve controller may compare the received measure related to the sensed pressure to an overpressure threshold. In the event the measure related to the sensed pressure surpasses the overpressure threshold value, the valve controller may be configured to provide a signal that indicates an overpressure event has occurred.
