In refineries, the process media flowing through valves are
primarily liquids. With liquids, critical operating conditions
caused by cavitation or flashing may occur. Symptoms are, for
instance, increased noise emission, valve and pipe component
erosion or low-frequency mechanical vibration in the valve and the
connected pipeline. Under these conditions, in particular,
neglecting details can result in negative influences on plant
performance and costs of ownership. Unfortunately, common practice
today is to select control valves in a "quick and dirty" fashion,
because the phases of planning, bidding and order processing are
connected with significant pressures of cost and time.
