Yes, you can. I'm not sure on the hydraulic setup on your Yanmar and I can't see from the pictures as to how many hoses will connect to the valve. You have the 4 work port hoses that go to the cylinders. On on open center system you will have 3 more, pressure inlet, power beyond outlet, and return to tank. The configurtation of these 3 ( or maybe 2) hoses and your Yanmar's hydraulics will determine how the valve should be configured.
