The control fluid is controllable in dependence upon an electrical or magnetic field which is applied to the control fluid. A control unit (11) is provided to control the pressure and/or flow of the control fluid. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for the control of a main fluid flow through a piloted fluid control valve. USE - The piloted fluid control valve may be used to control relatively large fluid flows and may be in the form of a proportional directional valve, a regulating valve, or a high-response regulating valve. ADVANTAGE - A high control dynamic can be achieved in a simple and reliable manner.de608620670patent102005021850
