Beschreibung
Zusammenfassung:	Valve assemblies may be configured to perform a valve proving test as part of an operational cycle of a combustion appliance coupled to the valve assembly. The valve assembly may include a valve body having a fluid path, first and second valves situated in the fluid path, first and second valve actuators, and a pressure sensor in fluid communication with an intermediate volume of the fluid path between the first and second valves. A valve controller may monitor a measure related to a pressure in the intermediate volume. The valve controller may then output a signal if the measure related to the pressure in the intermediate volume meets and/or exceeds a threshold value, where the threshold value is determined based on a measure related to an initial pressure in the intermediate volume and a known test duration.
