ROSS valves actuate cylinders that align logs before entering saws or the debarker.

Logs are dogged down prior to sawing the cant. Durability and a high tolerance to dirt are critical here.

With saws raising and lowering, boards are cut to length before being stacked. Speed and consistency are crucial at this stage.

Diverters on the drop sorter knock the lumber into the appropriate bins. ROSS valves ensure that tipples operate consistently, so that missorting doesn't become a problem.
