Hi gentlemen you that have worked with these outflow and safety valves might know the answer to my question. I am currently overhauling a safety valve 103036-5 (series 3) and the cmm I have 21-30-38 airesearch just have the ipl and information listing series 1 and series 2 and it does not make any reference to series 3 anywhere in the manual. By any change do you know what's the technical differences between series 3 and these series 1 and 2? thanks for your help.
