PURPOSE: To prevent the self-action of an actuator through flow rate control with a throttle section at a meter outlet side, by using a two-way throttle valve having two throttle sections at the meter outlet side and meter inlet side, to control the rate of flow to the actuator. CONSTITUTION: When a fixed pump 3 is caused to perform unloaded operation through a compensation valve 11 and valves 4, 20 are placed in positions shown in the drawing, a predetermined flow rate of a fluid is supplied to a port 36 from the meter-inlet-side throttle section 4a of the valve 4 pressure-compensated by the pressure compensation valve 11. As a result, a double-rod cylinder (actuator) 1 is moved at a prescribed speed. In the deceleration of the cylinder 1, the valve 4 is operated and its meter-outlet-side throttle section 4b is compensated by a compensation valve 30 to control the rate of flow to regulate the self-action of the cylinder (actuator) 1.
