<p>A flow control valve includes a pressure compensating valve (5,65,85) and a first switching valve (2, 62, 82). The pressure compensating valve (5,65,85) is configured to enlarge an opening area of a variable orifice between a load pressure line (13, 73, 93) and a compensating pressure line (14, 74, 94) when a pressure of working fluid of the compensating pressure line (14, 74, 94) is smaller than a first set pressure, and narrow the opening area of the variable orifice when the pressure of the working fluid of the compensating pressure line (14, 74, 94) is larger than the first set pressure. The first switching valve (2, 62, 82) is configured to switch between a meter-cut operation and a neutral operation by an external operation, wherein the working fluid of the compensating pressure line (14, 74, 94) is drained in the meter-out operation, the working fluid of the compensating pressure line (14, 74, 94) is not drained in the neutral operation. The load pressure line (13, 73, 93) guides the working fluid to be supplied to an actuator (4, 64, 84).
