Abstract
A valve assembly 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 valve sealing members translatable between an opened position and a closed position, and one or more pressure sensors in fluid communication with an intermediate volume of the fluid path between the first and second valve sealing members. A valve controller may be in communication with the pressure sensor and may monitor a measure related to a pressure change rate in the intermediate volume. The valve controller may then output a signal if the measure related to a pressure change rate in the intermediate volume meets and/or exceeds a threshold value.
