Float on remote?

Okay the silver wheel knob is for the float,its stamped in the wheel. Theres an arrow that indicates counter clockwise for float. How many turns out, before you get float? Can you turn this out to far?In the picture you can see a bolthead on the lower side of the valve body,looks like another spot for remote hookup any idea how that would work. Thanks much. Don

Float is automatic on single-acting hydraulic systems by virtue of simply letting the oil out of the cylinder. Float on double-acting systems connects both ends of the cylinder so the oil can flow to either end of the cylinder as the rod moves in and out. This is accomplished by a third position on the spool that allows free flow of oil to either end of the cylinder and free bypass flow from the pump. In your case, it appears that you have a regular two-position spool that locks the cylinder in neutral, and you obtain float by opening the needle valve. One full turn should be plenty. If you only have one line, (gravity-drop, single-acting) opening the needle valve will have no effect. (there's no place for the oil to go, the other port is plugged)

I don't believe you can open that valve too far. I don't think it will screw out of the body with removing some sort of keeper, either a set screw in the side or a snap ring.

As to Fritz' description, I don't entirely agree. If you don't open that valve for a single acting (one hose) cylinder, the hydraulic system will be putting full pressure against that 2nd port with nowhere for it to go except relief valve.

As to the front plug, I'm not sure what that might be unless it's an alternate for one of the other two.

Larry, I think you may be right. I'm wondering, how
does the oil get out of the cylinder through that
needle valve, combined with the flow from the pump?
Is it possible there is a float position on the
spool, and that knob is actually a FLOW control?
