Upon completion of the investigation it was noted that the valve was visually inspected it was noted that the stator and x ray dot were dislodged.Therefore; the cam position/pressure could not be determined.The valve was dismantled and was examined under microscope at appropriate magnification: a scratch mark in the valve casing was noted.This is probably due to the valve receiving some form of impact.The cam mechanism was also damaged.Corrosion was noted on the stator and the x ray dot.The cam magnets were controlled.The magnets passed.Review of the history device records confirmed the valve product code 82-3162, with lot cjcbrd, conformed to the specifications when released to stock on the 22nd may 2008.The root cause of the corrosion could not be clearly determined.The root cause for the dislodged stator and x ray dot could be partly due to the valve receiving some form of impact, as well as the corrosion, this however could not be determined.Investigation for the corrosion issue on hakim valves is being followed with capa.Based on the results of this investigation no further action is required.Trends will be monitored for this and similar complaints.At the present time this complaint is closed.
