Lower Diaphragm Plate PN 43729 is being obsoleted and replaced with PN 43730. Plate 43729 was used only on Spring Assist Open V425 valves. PN 43730 is the current Diaphragm Plate used on all other configurations. It was determined the special plate 43729 which had a centering ring is not required because the spring is centered by the shaft guide and retained in application under spring compression.
