The present invention relates to a control valve for a freight train that can be operated in a cryogenic environment, which is made of cast iron so that it can be properly used in a cryogenic environment, while modularizing the inside so that breakdown repair and maintenance can be easily performed. According to the present invention, the control valve comprises: a main body (10); a braking pipe control unit (20) installed inside the main body (10); an auxiliary air passage control unit (30) installed inside the main body (10) to one side of the braking pipe control unit (20); a braking cylinder control unit (40) installed inside the main body (10) to one side of the auxiliary air passage control unit (30); and a control air chamber (50) installed inside the main body (10) as a lower part of the braking pipe control unit (20).

    본 발명은 주철로 제작되어 초저온 환경에서 적절히 사용할 수 있도록 하면서 내부를 모듈화하여 고장 수리 및 유지 관리가 간편하게 이루어지도록 하는 초저온 환경에서 운용이 가능한 화차용 제어 밸브에 관한 것으로, 본 제어 밸브는 본체(10)와, 상기 본체(10)의 내부에 설치되는 제동관제어부(20)와, 상기 제동관제어부(20)의 일측으로 상기 본체(10)의 내부에 설치되는 보조공기통제어부(30)와, 상기 보조공기통제어부(30)의 일측으로 상기 본체(10)의 내부에 설치되는 제동실린더제어부(40)와, 상기 제동관제어부(20)의 하부로 상기 본체(10)의 내부에 설치되는 제어공기실(50)을 포함한다.
