The invention discloses a pneumatic electronic parking brake integrated valve which is used for connecting with an air storage tank and a parking brake air chamber. The integrated valve comprises a relay valve assembly (M5), a solenoid valve assembly (M234), a parking brake controller assembly (M10), an upper shell (55) and a lower shell (101), the relay valve assembly (M5) comprises a relay valve (5), the solenoid valve assembly (M234) comprises a first solenoid valve (2), a second solenoid valve (3) and a third solenoid valve (4), the parking brake controller assembly (M10) comprises a parking brake controller (10), the upper shell (55) is detachably and fixedly connected with the lower shell (101), the solenoid valve assembly (M234) is adjacent to the relay valve assembly (M5), the mounting surface of the solenoid valve assembly (M234) is mutually perpendicular to that of the relay valve assembly (M5), both the solenoid valve assembly (M234) and the relay valve assembly (M5) are arranged in the upper shell (55), and the parking brake controller assembly (M10) is arranged at the bottom of the integrated valve and mounted in the lower shell (101). According to the integrated valve, the parking brake controller, three solenoid valves and the relay valve are effectively integrated, pipeline connection is simplified, manufacturing and assembling of components are simplified, and the integrated valve is compact in structure, low in cost and reliable in performance.
