Default Problem with moving mesh

I am trying to use a moving mesh to semi-steady state flow thru an orifice at various spool positions within a valve. I have set the boundary condition of the moving wall to .00005m/s to simulate a very slow moving wall. Next I am setting the time steps to 2sec and trying to solve for 15 positions (every .1mm). When I preview the moving mesh, the actual travel is orders of magnitude higher than what it should be. I am using Fluent 6.2.16. Please Help!!!!

i think that is sth related to scaling the boundary movement

The motion is described as a velocity within the boundary condition of the fluid and surface.

I have checked the scaling of the geometry of the model and everything seems to be OK.
