IP Class of SP90 actuator

I don't get it....
Can anyone tell me why the first number in the IP class changes on the SP90 valve when it mounted with the actuator down? It goes from 5 to 4 which mean it goes from being protected from dust to protected against objects with a diameter greater than 1mm.

@FlatBeach just a guess, gravity... the moving parts for the plunger are all on the underside and in the upside-down position they become more exposed. It's unlikely that anything would fall upwards and lodge in there when mounted normally.
