A controlled pressure release vault panel assembly is capable of functioning as a second, or auxiliary, relief port to allow the escape of fluid from the vault in the event of pressure build-up inside the vault or in an explosion event. The vault panel assembly may define an opening that includes a manhole cover assembly. The manhole cover assembly may also be vented, and may function as a primary vent. The vault panel assembly may include a retention assembly extending from the vault panel underneath a portion of the vault, enabling a limited range of motion of the vault panel for the escape of fluid and allowing the reseating of the vault pane on the vault once the pressure inside the vault approaches ambient pressures.

A fire hydrant having a valve seat flange with an integral liner. In one embodiment, the fire hydrant includes a valve seat flange disposed between a standpipe and a hydrant shoe. The valve seat flange includes a standpipe neck defining internal threads to directly connect to the standpipe and a base flange to directly connect to the hydrant shoe. The liner includes an outer peripheral edge that is entrapped within the valve seat flange and an inner circumferential surface defining threads for receiving the valve seat of a valve assembly. The present invention also discloses a process of manufacturing a valve seat flange, including the steps of: (a) manufacturing the liner, (b) incorporating the liner into a core with the outer peripheral region of the liner exposed, (c) placing the integral core/liner into the valve seat flange mold and (d) forming the valve seat flange around the liner with the valve seat flange entrapping the outer peripheral region of the liner.
