Abstract
This disclosure relates generally to valves, and more particularly, to gas valve assemblies. In one example, a valve leakage test may be performed on a valve assembly including a valve body with a first valve and a second valve, where the valves may be positioned across a fluid path in the valve body with an intermediate volume between the valves. A pressure sensor may be in fluid communication with the intermediate volume and may sense a measure that is related to the pressure in the intermediate volume. The pressure sensor may communicate with a controller to determine a measure that is related to a pressure change in the intermediate volume and compare the measure that is related to a pressure change to a first and/or second threshold value. The controller may output a signal if the measure meets and/or exceeds the first and/or second threshold value.
