Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed: 1. A control member assembly for a control valve, the control member assembly comprising: a control member; a retainer secured to one end of the control member, the retainer having a body portion, the body portion having a longitudinal axis, a top surface, and a bottom surface, the bottom surface having a first portion that extends parallel to the longitudinal axis and a second portion that extends away from the first portion, the second portion being angled mor…
