ABSTRACT:
A top entry expansible tube valve has a generally cylindrical receptacle in the valve body disposed transversely of the flow passageways to receive a slotted core sleeve with a central barrier and expansible elastomer sleeve sealed around it. A generally circular cap closure is bolted to the valve body to seal around the access opening and a perforated sleeve is secured between the cap closure and the core sleeve so that the cap closure and core sleeve, with expansible tube thereon, may be removed as a unit for inspection.
