The two-way air control valve is characterized in that a spacer bush (30) is sheathed between the air cylinder (20) and the piston rod (22), and one side of the spacer bush (30) is fixedly connected to the valve body (10) and the other side of the spacer bush (30) is rotatably connected to the air cylinder (20). The air cylinder portion of the two-way air control valve is rotatable and provides convenience in installation for a client during usage, and the service life of a sealing gasket is prolonged.
