Abstract: PURPOSE: To enable the efficient use of a power of a pressure fluid source, by a method wherein, in a direction-switching valve with pressure compensation, when the control amount of the direction-switching valve exceeds a given value, a pressure compensating function of the pressure compensate valve is caused to stop and  a whole amount of a pressure fluid is supplied to an actuator.  
     CONSTITUTION: Through the rightward movement of a spool 25, a bridge path 23 and a toroidal channel 27a are connected in a throttle state, and with a pressure compensate valve 4 actuated, a pressure fluid is fed so as to hold a constant pressure at the front and the rear of said throttle. Through the further rightward movement of the spool 25, a small-sized part 36a couples together the bridge 23 and the toroidal channel 27a, and thereby said parts equalize in a fluid pressure. Said fluid  pressure is exerted on a spring chamber 53 of the pressure compensate valve 4  through a pilot path 40, and a pressure chamber 52 of the pressure compensate  valve 4 and the spring chamber 53 equalize in the fluid pressure. As a result, the  pressure compensate valve 4 stops functioning and a discharge fluid in a pressure  fluid source 3 is all fed to the direction switching valve 2.
