> Any open-center valve is a "power-beyond" valve, < That is another guy posting info about which he knows little or nothing. Plumbing the loader valve as you instruct will subject the return ports and galleys of the valve to pressures up to relief pressure, depending on the load on the hitch. Not a good idea. Power beyond valves use 3 connections; in (from pump or relief valve); out (return from work ports to reservoir); and power beyond (to another function). Some valves are convertible to power beyond, many are not. Certain Gresen valves will blow the spool seals almost instantly when the return is pressurized much at all, as many Arps backhoe owners have learned.
