A sealing assembly for use in a valve plate assembly includes a sealing ring and a retention spacer. The sealing ring has a radial ring section and an axial ring section, the axial ring section extends axially from the radial section and includes an outer diameter surface and a contact face, the contact face includes a contact surface and an annular slot, and the contact surface is located radially outward relative to the annular slot. The retention spacer is configured to be positioned adjacent the sealing ring.

1. A butterfly valve plate sealing assembly comprising: a plate having a first outer diameter surface and an annular groove, the annular groove formed in an outer periphery of the plate and including an opening section and a cavity section, the opening section extending from the first outer diameter surface to the cavity section;a sealing ring having a radial ring section and an axial ring section, the radial ring section extending through the opening section of the annular groove into the cavity section of the annular groove, the axial ring section disposed in the cavity section of the annular groove and extending axially from the radial section toward a surface defining the cavity section of the annular groove, the axial ring section including a second outer diameter surface and a contact face, the contact face adjacent to the surface defining the cavity section and including a contact surface and an annular channel, the contact surface configured to contact the surface defining the cavity section and located radially outward relative to the annular channel, the annular channel forming a gap between the surface defining the cavity section and at least a portion of the contact face; anda retention spacer positioned adjacent the sealing ring and within the opening section of the annular groove. 2. The butterfly valve plate sealing assembly of claim 1, wherein the axial ring section is substantially orthogonal relative to the radial ring section. 3. The butterfly valve plate sealing assembly of claim 1, wherein the sealing ring has an inner diameter surface and the annular channel extends to the inner diameter surface. 4. The butterfly valve plate sealing assembly of claim 1, wherein the contact face of the axial ring section includes a torsion stop configured to contact the surface defining the cavity section of the annular groove, the torsion stop located radially inward relative to the annular channel. 5. The butterfly valve sealing assembly of claim 4, wherein the torsion stop is continuous around the sealing ring. 6. The butterfly valve sealing assembly of claim 4, wherein the torsion stop is segmented around the sealing ring. 7. The butterfly valve plate sealing assembly of claim 1, wherein the annular channel is continuous around the sealing ring. 8. A butterfly valve plate sealing assembly comprising: a plate having a first outer diameter surface and an annular groove, the annular groove formed in an outer periphery of the plate and including an opening section and a cavity section, the opening section extending from the first outer diameter surface to the cavity section;a sealing ring having a radial ring section and an axial ring section, the radial ring section extending through the opening section of the annular groove into the cavity section of the annular groove, the axial ring section disposed in the cavity section of the annular groove and extending axially from the radial section toward a surface defining the cavity section of the annular groove, the axial ring section including a second outer diameter surface and a contact face, the contact face adjacent to the surface defining the cavity section and including a contact surface and an annular channel, the contact surface configured to contact the surface defining the cavity section and located radially outward relative to the annular channel, the annular channel forming a gap between the surface defining the cavity section and at least a portion of the contact face;a retention spacer positioned adjacent the sealing ring and disposed at least partially within the annular groove,wherein the contact face of the axial ring section includes a torsion stop configured to contact the surface defining the cavity section of the annular groove, the torsion stop located radially inward relative to the annular channel. 9. The butterfly valve sealing assembly of claim 8, wherein the torsion stop is continuous around the sealing ring. 10. The butterfly valve sealing assembly of claim 8, wherein the torsion stop is segmented around the sealing ring. 11. The butterfly valve plate sealing assembly of claim 8, wherein the annular channel is continuous around the sealing ring. 12. The butterfly valve plate sealing assembly of claim 8, wherein the retention spacer is positioned within the opening section of the annular groove and adjacent the sealing ring. 13. The butterfly valve plate sealing assembly of claim 8, wherein the axial ring section is substantially orthogonal relative to the radial ring section. 14. The butterfly valve plate sealing assembly of claim 8, wherein the sealing ring has an inner diameter surface and the annular channel extends to the inner diameter surface.
