A chromatography column has valve and method for filling it with a slurry of media, the valve utilizing a piston to compact the slurry in the column. The piston moves through a cavity in communication with both a slurry inlet and slurry ports which are in communication with the interior of the chromatography column. The piston assists in compacting the slurry within the column. The method of filling the column does not require disassembly of the column. The piston may also be utilized to change the valve position from a slurry fill position to a normal operation position or other position.
