Abstract
A fluid flow control valve has a body enclosing a transfer passageway whose bounding surface is profiled to provide streamline flow conditions. The passageway is constricted by means of a piston-like valve moving transverse to the direction of fluid flow. A profiled shield protects the valve from direct impingement of fluid.
