The Model 6000 sectional valve is a directional control valve designed for use with parallel, conventional and series circuit hydraulic systems, of open or closed center types. Model 6000 inlets, mid-inlets, outlets and spool sections provide a compact envelope to save Standard spool types include single acting, double acting, motor and double acting float, with non- standard custom designed spools available. Most design requirements can be met with a variety of work port options and end mechanisms. • "Zero leak" spool seals • 4000 psi maximum operating pressure — see page 6. • Open center...

The term "Low Effort" was associated with this spool type as a result of the successful design efforts to reduce the variety of flow forces on the spool during The machined notch design in detail A directs the fluid entering the spool land area in such a way as to create a reactionary force on the spool that reduces the force created by the high velocity. The machined notch in detail B cushions the exhausting fluid from the land area by directing the initial flow jet back against the housing land when the grooves are first exposed, then vertical to the spool axis as the groove completely...
