The invention discloses a solenoid control valve for an engine VVT system. The solenoid control valve comprises a valve sleeve and a solenoid coil part connected with the valve sleeve. The solenoid coil part is mainly composed of a shell, a coil, a tubular yoke and a plunger, wherein the coil is arranged on the inner side of the shell, the yoke is arranged on the inner circumference side of the coil and used for forming a magnetic circuit, and the plunger is arranged on the inner side of the yoke. The yoke comprises a front-end yoke portion, a rear-end yoke portion and a yoke check ring arranged between the front-end yoke portion and the rear-end yoke portion. The front-end yoke portion, the yoke check ring and the rear-end yoke portion are welded into a whole. The solenoid control valve is simple in structure, high in accuracy, simple in assembly process and good in wear resistance.
