Zusammenfassung:	A valve cavity cap arrangement including an insert and a threaded cap is provided in combination with a valve body defining a valve cavity, a central passage, and at least one offset passage. The insert is received in the valve cavity and includes an inner annular sealing surface sized to seal against a portion of the recessed surface surrounding the central passage, an outer annular sealing surface sized to seal against an outer periphery of the recessed surface, surrounding the offset passage(s), and a solid web portion extending between the inner and outer annular sealing surfaces. The threaded cap includes an outer threaded portion threadably engaged with an internal threaded portion of the valve cavity, a central end portion configured to apply a first sealing force to the inner annular sealing surface, and an outer end portion configured to apply a second sealing force to the outer annular sealing surface.
