摘要：
A valve assembly, including a quarter turn ball valve (498), an insert (402) carried by the valve housing (400D), and a flange (406), rotatably carried on the insert (402). The flange (406) is used to secure the valve assembly in a fluid system and the assembly and disassembly of the valve assembly is facilitated by the adjustable position of the flange (406). A check valve carried in the housing assembly for preventing fluid flow from the outlet port (422D) to the inlet port (420D) when an associated fluid system is unpressurized.
