A valve that has at least one internal port on a valve core and at least one an internal slot in a valve body. The valve core is biased into a position wherein the port of the valve core is aligned with a sealing surface of the valve body thereby prohibiting fluid flow through the valve. The valve core is slidable such that the port of the valve core becomes aligned with the internal slot of the valve body thereby allowing fluid flow through the valve. Another valve includes a self-aligning valve seat carrier which is pivotably engaged with a valve core member. The self-aligning valve seat carrier engages a sealing surface in a valve body to prohibit fluid flow through the valve, but the valve core is slidable such that the self-aligning valve seat carrier disengages from the sealing surface in order to allow fluid flow through the valve.

1. A valve having a fluid flow path therethrough and comprising: a valve body which includes a sealing surface; a valve core disposed in said valve body and having a central throughbore which defines a fluid flow area through said valve core; a self-aligning valve seat member pivotably engaged with said valve core, said self-aligning valve seat member including a sealing surface; and spring means engaged with said valve body and said valve core, said spring means not being disposed in the fluid flow path of said valve, said spring means biasing said valve core into a closed position wherein said sealing surface of said self-aligning valve seat member engages said sealing surface of said valve body thereby prohibiting fluid flow through said valve, said valve core being slidable generally within said valve body to an open position wherein said sealing surface of said self-aligning valve seat member disengages from said sealing surface of said valve body thereby allowing fluid flow through said valve. 2. A valve as defined in claim 1, wherein said self-aligning valve seat member includes a hollow portion which allows fluid flow through the self-aligning valve seat member. 3. A valve as defined in claim 1, wherein said self-aligning valve seat member includes a barb which engages said valve core. 4. A valve as defined in claim 1, wherein said self-aligning valve seat member includes a ball which engages a corresponding socket on said valve core. 5. A valve having a fluid flow path therethrough and comprising: a valve body which includes a first sealing surface and a second sealing surface; a valve core disposed in said valve body and having a central throughbore which defines a fluid flow area through said valve core; a sealing member disposed on said valve core and engaged with said first sealing surface of said valve body; a self-aligning valve seat member pivotably engaged with said valve core; a sealing member disposed on said self-aligning valve seat member; and spring means engaged with said valve body and said valve core, said spring means not being disposed in the fluid flow path of said valve, said spring means biasing said valve core into a closed position wherein said sealing member on said self-aligning valve seat member engages said second sealing surface of said valve body thereby prohibiting fluid flow through said valve, said valve core being slidable generally within said valve body to an open position wherein said sealing member on said self-aligning valve seat member disengages from said second sealing surface of said valve body thereby allowing fluid flow through said valve.
