Pressure fluid supply port, output port, discharge port, supply valve seat and discharge valve seat in a passage that communicates the output port with the supply port and discharge port, and these valve seats. It is equipped with a valve part that has a supply valve element and a discharge valve element that open and close, and a drive part that drives the valve part, and the magnitude of the driving force of the drive part and the acting force of the fluid fed back from the output port to the feedback chamber is determined. A pressure control valve in which the valve body is driven by a pressure control valve, wherein the drive section includes a pressurizing chamber for outputting an acting force in the same direction as the driving force. 2. The pressure control valve according to claim 1, wherein the drive section includes a pressure reduction chamber for outputting an acting force in a direction opposite to the drive force.
