The invention discloses a brake valve assembly. A brake pressure reducing valve is arranged in a brake pressure reducing valve cavity of a casing, a liquid-controlled conversion valve is arranged in a liquid-controlled conversion valve cavity of the casing, and the brake pressure reducing valve cavity and the liquid-controlled conversion valve cavity are communicated; the outer end of an oil return opening, the outer end of a first pressure supply opening, the outer end of a second pressure supply opening, and the outer end of a brake opening are separately connected with a hydraulic pipeline of a brake system of an aircraft; the inner end of the oil return opening, and the inner end of the first pressure supply opening are separately communicated with the brake pressure reducing valve cavity; the inner end of the second pressure supply opening is communicated with air inlets of the liquid-controlled conversion valve, and the inner end of the brake opening is communicated with an oil outlet of the liquid-controlled conversion valve. When the brake valve assembly disclosed by the invention is used in normal braking, the pressure of a pressure supply source of the brake system is reduced to needed brake pressure; when the aircraft is braked at a take-off line, the pressure of the pressure supply source of the brake system is directly output without reduction; a normal braking function and a braking function at the take-off line can be realized through the foot control of a pilot. According to the brake valve assembly disclosed by the invention, the brake system is simplified, and the reliability and the safety of the brake system of the aircraft are improved. In addition, independent accessories are integrated in the brake valve assembly disclosed by the invention, and the brake valve assembly is designed and manufactured according to modularization, so that the brake valve assembly is convenient to use and maintain.
