The invention discloses a control valve and a heat exchange system. The valve head is arranged at one end of the valve body, at least part of the driving device is installed in the valve head, the driving device is provided with an output shaft, the valve seat is located between the valve body and the valve head, the valve needle is in transmission connection with the output shaft, a valve needle runner is arranged in the valve needle, and the valve needle can move in a reciprocating mode. Wherein the valve body is provided with a valve needle cavity for accommodating the valve needle, and first, second, third and fourth flow channel ports communicated with the valve needle cavity, and the valve needle comprises a first side channel and a second side channel which are communicated with a valve needle flow channel and are positioned above the sealing device. The high-pressure reversing valve is small in overall size, simple in structure, small in overall flow resistance, smooth in high-pressure reversing and small in inner leakage.
