Beschreibung
Zusammenfassung:	A valve comprising a body having an interior cavity, an inlet port and an outlet port; an upstream seat and a downstream seat positioned within the cavity, each seat including a bore in alignment with the inlet and outlet ports to define a flow passage through the valve body; a closure member movably positioned between the seats to either open or close the flow passage; a seat-to-closure member seal defined between each seat and the closure member, the seat-to-closure member seal defining a first area between the seat-to-closure member seal and the bore of the upstream seat; wherein the upstream seat includes a sealing member between the seat and the valve body which is positioned asymmetrically around the bore; and wherein the sealing member defines a second area between the sealing member and the bore which is larger than the first area.
