弁。 The valve body includes a spool having a spool hole formed therein, and a spool slidably provided in the spool hole of the valve body. is an electromagnetic proportional control valve having a pilot chamber into which hydraulic oil supplied to the pump port is introduced via an orifice, the spool having a cross-sectional area larger than the orifice, and the pump port having a pilot chamber formed therein; A horizontal hole is formed that extends from the facing outer circumferential surface in a direction intersecting the axis of the spool and is located adjacent to the pilot chamber in the axial direction of the spool, and between the horizontal hole and the pilot chamber. An electromagnetic proportional control valve characterized in that an orifice is formed along the axis of the spool, and a filter is provided inside the horizontal hole to remove dust mixed in the hydraulic oil flowing into the orifice.
