An oil pump control valve including a valve for controlling a flow of a fluid, and a solenoid for operating the valve, the valve comprising: a tube-like holder having a hollow internal space, configured to include an inflow port formed at one end thereof and a control port formed at a middle end thereof, the inflow port and the control port being connected to each other in the hollow internal space; a tube-like first valve sheet formed in the middle end of the holder, configured to include an inflow hole connected to the inflow port, which is formed at a first end of the first valve sheet, and a discharge hole connected to the control port, which is formed at a middle end of the first valve sheet; a ball valve mounted in the first valve sheet to open or close the inflow hole; a second valve sheet coupled to a second end of the first valve sheet, which is opened; and a load mounted in the second valve sheet, one end thereof being extended through the second valve sheet to come into contact with the ball valve, wherein, when the solenoid is operated, the ball valve is moved to open the inflow port, wherein the solenoid comprises: a bobbin having an external circumferential surface around which a coil is wound; a core mounted in the other end of the bobbin, a part of the core being inserted into the bobbin; a plunger mounted in the bobbin, the other end of the load being coupled to the plunger; and a spring mounted between the plunger and the core to elastically support the plunger, wherein the solenoid is coupled to the other end of the holder, characterised in that a yoke is mounted in one end of the bobbin and in that a guide is mounted between the bobbin and the plunger to guide movement of the plunger. a tube-like holder having a hollow internal space, configured to include an inflow port formed at one end thereof and a control port formed at a middle end thereof, the inflow port and the control port being connected to each other in the hollow internal space; a tube-like first valve sheet formed in the middle end of the holder, configured to include an inflow hole connected to the inflow port, which is formed at a first end of the first valve sheet, and a discharge hole connected to the control port, which is formed at a middle end of the first valve sheet; a ball valve mounted in the first valve sheet to open or close the inflow hole; a second valve sheet coupled to a second end of the first valve sheet, which is opened; and a load mounted in the second valve sheet, one end thereof being extended through the second valve sheet to come into contact with the ball valve, wherein, when the solenoid is operated, the ball valve is moved to open the inflow port, wherein the solenoid comprises: a bobbin having an external circumferential surface around which a coil is wound; a core mounted in the other end of the bobbin, a part of the core being inserted into the bobbin; a plunger mounted in the bobbin, the other end of the load being coupled to the plunger; and a spring mounted between the plunger and the core to elastically support the plunger, wherein the solenoid is coupled to the other end of the holder, characterised in that a yoke is mounted in one end of the bobbin and in that a guide is mounted between the bobbin and the plunger to guide movement of the plunger. a bobbin having an external circumferential surface around which a coil is wound; a core mounted in the other end of the bobbin, a part of the core being inserted into the bobbin; a plunger mounted in the bobbin, the other end of the load being coupled to the plunger; and a spring mounted between the plunger and the core to elastically support the plunger, wherein the solenoid is coupled to the other end of the holder, characterised in that a yoke is mounted in one end of the bobbin and in that a guide is mounted between the bobbin and the plunger to guide movement of the plunger.
