CNC Brass Pneumatic Valve Spool Precision Turned Flow-Control Part

This custom CNC turned brass valve spool is intended for pneumatic directional valves used in automated assembly fixtures, where compressed air must be switched to extend or retract clamping cylinders during component positioning and fastening operations.
Its stepped lands and circumferential grooves define the spool geometry and the interfaces with the mating valve body. The critical checks are the land diameters, groove widths, concentricity, surface finish and clearance specified on the drawing.
Brass offers good machinability, but the alloy should be selected according to working pressure, air or fluid compatibility, wear conditions and seal materials. Before ordering, provide the valve-body bore dimensions, operating conditions and required port arrangement so the spool can be manufactured to the intended fit.
