This invention provides a direct-acting, high-pressure, high-flow-rate three-way proportional pressure reducing valve, comprising a valve sleeve, a valve core, a proportional electromagnet, and a push rod. The valve core is installed inside the valve sleeve and can slide within the valve sleeve. One end of the valve core contacts the end face of the push rod, which is installed inside the proportional electromagnet. The proportional electromagnet is connected to the valve sleeve. The valve sleeve has an inlet port P and an outlet port T. The valve core has a first annular groove and a second annular groove. The areas between the two ends of the valve core and the valve sleeve form a first control cavity and a second control cavity.

The diameters of the inlet and outlet ports are equal to the large-diameter end face diameter of the valve core. By increasing the large-diameter end face diameter of the valve core, the flow rate at the inlet or outlet port can be increased, thus achieving high-flow-rate control and decoupling control of the output pressure and flow rate of the three-way proportional pressure reducing valve.
