Abstract
A fluid flow control valve has a diaphragm for sealing against a valve seat. The diaphragm includes a bleed hole for passing fluid from one side of the diaphragm to the other. A debris arrestor comprising a one-piece flexible tag is inserted into the bleed hole by deforming the tag to pass therethrough. The tag after insertion expands to retain itself in the bleed hole.
