Abstract:
1. Equipment for performing seat leakage detection on a valve assembly including at least two valves to be tested, the equipment comprising: a plurality of manifold passages defining a plurality of fluid paths; at least one flow sensor configured to sense flow in a fluid path of the plurality of fluid paths containing the at least one flow sensor; and a plurality of auxiliary valves provided in relation to the at least one flow sensor and configured to be closed or opened to alter paths for potential flow through the plurality of fluid paths from an upstream side of the valve assembly to a downstream side of the valve assembly, wherein, while each of the at least two valve assembly valves remain closed, at least a first auxiliary valve of the plurality of auxiliary valves is closed to enable flow of fluid to test a first valve of the at least two valve assembly valves and, subsequently, at least another auxiliary valve of the plurality of auxiliary valves is closed to enable flow of fluid to test a second valve of the at least two valve assembly valves.
