Furthermore, it has a discharge port on both sides, and a valve stem that is inserted into a valve hole that communicates these ports is connected to a valve seat between one output port and supply port, and the other output port and discharge port. In a directional valve equipped with a poppet-type elastic valve member that separates the valve, the valve seat is responsible for shutting off the flow of fluid from the supply port to the output port, and the valve member moves from the center side of the supply port to both ends of the valve body. A valve seat that abuts toward the side is formed by a tapered surface, a valve seat that abuts from both ends of the valve body toward the center is formed by a corner portion, and the valve member abuts the valve seat of the tapered surface. A directional control valve characterized in that a seal diameter when the valve body contacts a valve seat formed by a corner portion is larger than a seal diameter when the valve body contacts a valve seat formed by a corner portion.
