ABSTRACT:
A fluid flow control device, sometimes called a variable fluid restrictor control valve or severe service control valve. These valves employ a moveable plug and are used to control high pressure fluids e.g. superheated steam. The valve of the invention provides axial flow passageways for the fluid, which have right-angled turns. The passageways are either on the radially outer surface of the plug or within an annular sleeve through which the plug is moveable.
