The invention discloses a switch valve for railway vehicle equipment, and belongs to the technical field of railway vehicle braking, the switch valve comprises a spring cover and a valve core seat which are arranged up and down, the valve core seat is provided with a first accommodating cavity, and the spring cover is provided with a second accommodating cavity; the valve element base is provided with an inflation channel and an air inlet channel, and the inflation channel communicates with the first containing cavity. The valve element is arranged in the first containing cavity in a sliding mode, a first inner cavity is formed in the first end of the valve element, and a plurality of air inlet holes communicating with the first inner cavity are formed in the valve element in the radial direction; the second end of the valve element is provided with a second inner cavity. The adjusting screw is arranged at the end, away from the valve element base, of the second containing cavity in a position-adjustable mode. The pressure limiting assembly is located in the second containing cavity and arranged between the valve element and the adjusting screw. The air inlet is provided with a structure with a one-way function, and it is ensured that the air inlet can only be opened in one direction; and meanwhile, the inlet valve limit adjustment and the outlet valve limit adjustment adopt a serial connection structure, so that small-range adjustment of numerical values after integral installation is facilitated.
