Abstract: A block forged swing check valve body includes a fully encapsulated seat ring. The swing check valve body includes a through hole and a chamber having a shelf portion defined by a D-shaped passageway. The shelf portion overlies an annular shoulder that encapsulates the valve seat. Methods for the manufacturing and use thereof are also provided.

Abstract: A valve includes a valve body including a housing. The housing has a first internal housing surface defining an internal chamber. The valve further includes a valve assembly including a cartridge and a sleeve fixedly secured to the cartridge. The sleeve has an internal sleeve surface defining an interior cavity. The valve assembly further includes a plug positioned within the interior cavity and including a plug body. The plug body has an external plug surface configured to sealingly engage the internal sleeve surface. The cartridge is removably coupled to the housing such that the sleeve is disposed within the internal chamber of the housing.

Abstract: A valve assembly includes a plug extending along a central axis and including a plug body having an external plug surface. The external plug surface tapers radially outwardly in a first direction along the central axis. The valve assembly further includes a sleeve having an internal sleeve surface defining an interior cavity. The internal sleeve surface tapers radially outwardly in the first direction. The plug body is positioned within the interior cavity of the sleeve. The plug is rotatable about the central axis relative to the sleeve, and the plug is also translatable along the central axis relative to the sleeve.

Abstract: A valve assembly includes a cartridge configured to be removably coupled to a valve body. The cartridge includes a hub. The valve assembly further includes a sleeve encapsulating at least a portion of the hub and having an internal sleeve surface defining an interior cavity.

Abstract: A Y-globe valve assembly includes a valve body having a neck portion defining a chamber with a circumferential wall and an integrated pressure relief passageway formed in the circumferential wall and communicating between the chamber and a flow passageway downstream of a valve port. A valve includes a core having an outer surface spaced radially inwardly from the circumferential wall of the valve body so as to define an annular space therebetween. The pressure relief passageway is in fluid communication between the annular space and the flow passageway upstream of the valve port when the valve is in at least the open position.
