Why not? You just plumb one work port to the single acting cylinder and the other work port back to the reservoir. Ports are generally P to T in neutral with A and B blocked. Move the valve in one direction and the pressure goes to the head end of the cylinder and since the other work port B is already plumbed tothe reservoir, nothing happens there. Move the valve the other direction and the cylinder port returns to the resevoir, allowing the loader to drop. The pressure is then diverted through the other port to the reservoir. The key is to tie the second work port to the tank or reservoir... if it is plugged, the pressure will be 'dead-headed" against the plug and the system will build heat that it doesn't need.
In reality the valve is properly called a 4-way valve, not a 2 way, but that's just a difference in how people use the terminology.
