In this study directional control valves being the elements of industrial hydraulic circuits have been examined. A viscous fluid leakage between the spool ( piston of which the surfaces being machined parallel to each other ) and the valve body has been obtained. It has been seen that the misalignment within the piston-cylinder system increases the fluid leakage. Analysis has been expanded to cover the conical spool surfaces. It was concluded that for reduced leakage (as far as possible ) the misalignment, piston length and the value of surface coning should be selected properly. The study has been performed by non-dimensional parameters.
