Counter-flashing (or cover flashing, cap flashing) is a term used when there are two parallel pieces of flashing employed together such as on a chimney, where the counter-flashing is built into the chimney and overlaps a replaceable piece of base flashing.
Extent of the pressure losses in pipes and elbows between the valve and, for example, a vessel at constant pressure, influences valve outlet pressure and, hence, flow status. Either flashing or cavitation can exist when the operating point is near the sharp transition from cavitation to flashing at xF = 1.n case of flashing or two-phase flow, it is imperative that a sufficiently large nominal valve size be selected to limit average flow velocity on the downstream side of the valve, thus minimising the problems described in the section on cavitation and flashing.
