This disclosure relates generally to valves, and more particularly, to gas valve assemblies. In one illustrative but non-limiting example, a valve assembly may include a valve body, a valve situated in a fluid path of the valve body, a valve actuator for selectively moving the valve actuator, one or more sensors in communication with the fluid path, a controller secured relative to the valve body and in communication with the sensors, and memory operatively coupled to the controller. A user interface may be in communication with the memory and the controller and may be configured to receive a selection from a user for selecting one of two or more selectable options from the memory. The controller may compare sensed parameters to threshold values associated with the selected option. The user interface may have a lock on it to prevent tampering and to provide accountability.
