<p>A flow force compensating method for a flow control valve and a flow control valve using the same method, in which a spool is supported by hydrostatic bearings (20) within a sleeve and fluid flow from the hydrostatic bearing flows into a valve space defined between a spool land (2) and a circumferential groove of the sleeve, wherein a circumferential groove (7) is formed in the spool land, bearing fluid flow flowing out of the bearing into the valve space defined between the circumferential groove and the sleeve groove is directed toward a central axis of the spool, and control flow is swirled by the bearing fluid flow, thereby compensating a flow force, acting on the spool. <IMAGE></p> |
