Abstract

Equipment and methodology are provided for performing seat leakage detection on a valve assembly including at least two valves to be tested, wherein, while both of the valve assembly valves remain closed, at least a first shut off valve of a plurality of shut off valves is closed to enable flow of fluid through manifold passages of a plurality of manifold passages to test the first valve of the valve assembly valves and, subsequently, at least another shut off valve of the plurality of shut off valves is closed to enable flow of fluid through manifold passage of the plurality of manifold passages to test the second valve of the valve assembly valves.
