Dont know how to model an UNmodded rainbird cp-100 1" valve. DONT send me to the GGDT website where he details a MODDED valve, I have already been there and since I do not have a Modded valve, I dont belive it works well with my situation. Just needed to know how to model an UNmodded valve Thank You,

Same values... except you might drop the pilot volume .1-.07 cubic inches, and the vent is much smaller. (dunno how big. Maybe .05" or so.)

I'll point out that this vent is ported to the barrel, and GGDT can't do that [anymore]. This will cause your model to preform better than it really would.
