The first handle on the right with the longest end is the spool with float. This can not be changed, You would connect the hoses to that spool to operate the float option.

In the float position, work ports are open to the return and the oil goes to the next spool or handle. This allows the cylinder to drift or float and does not lock into position but the handle does lock into place.

This type of spool is used on loaders or snow plows. This allows the hydraulic cylinder to float, all ports are connected to the reservoir when the valve is in the float position.

When the operating handle is held in the extreme "down" position, oil is permitted to flow in either direction. This allows any cylinder attached to those ports to be moved in and out by external forces. On my son's bulldozer, for instance, it allows the dozer blade to follow the terrain when scraping a pile of stones into a low spot.

Staff Answer
Closed center hydraulic systems rely on closed center circuits, or systems of interconnected components that move fluid, to provide pressure to the control valves, which partially or fully close or open, based on sensors that determine the level and rate of flow. The pump moves only minimal hydraulic fluid through the closed circuits until a valve is actuated by an operator. This allows the valve's spool to operate without an open return path to the hydraulic system's fluid reservoir. This configuration allows multiple valves to connect to different operations while sharing equal system pressure.
