Abstract
A flow path velocity modifier allows a control member of a control valve to operate very close to a seat ring while reducing or eliminating restricted flow areas, which results in greatly reduced flow velocity fluctuations, which results in smoother flow, between the sealing element and the seat ring. As a result, sealing elements made of relatively soft materials may be used without fear of damage from high flow velocities.
