The invention relates to an improved high-pressure multiway reversing valve which comprises a valve body. The improved high-pressure multiway reversing valve is characterized in that an oil inlet loop and an oil outlet loop. A check valve, a valve rod, an overload relief valve, an operating handle and a sliding positioning device are further arranged in the valve body. The operating handle is connected with one end of the valve rod, the other end of the valve rod is connected with the sliding positioning device, the oil inlet loop is provided with an oil inlet, the oil outlet loop is provided with an oil outlet, and the overload relief valve is arranged at the position of the oil inlet. The improved high-pressure multiway reversing valve has the advantages that the reversing valve is compact in product structure, light in weight and simple and convenient to operate, operating force is light when the valve rod is in reversing, pressure loss is reduced, the applied range is wide, safety performance is good, and stability performance is high in work.
