A streamlined control valve with integral seating means having a flow characteristic determining contour and being part of a gradually expanding flow path formed between said contour and a movable central valve plug with a streamlined contour facing an orifice and being designed to have an abrupt area change producing configuration on its discharge side.
Control valve with integral seating means and movable plug means capable of generating together low fluid flow resistant passages at the maximum retraction of said plug means from said sealing means and a turbulence and higher fluid resistant producing throttling path at lesser distances of said plug from said seating means, comprising: (a) a valve housing having inlet and outlet ports and a central reduced diameter orifice having a longitudinal axis which is located perpendicular to the axis of the inlet or outlet port, streamlined flow passages with in...
