Hydraulic systems are classified as open-center or closed-center depending upon the type of selector valves used. In an open-center system that has more than one selector valve, the valves are arranged one behind the other (in series). In a closed-center system, the valves are arranged parallel to each other. An open-center system has fluid flow but no pressure in the system when the selector valve is off. In a closed-center system, fluid is under pressure throughout the system when the hydraulic pump is operating.
