6. The electronic water valve of claim 5, wherein the sealing rib is disposed on an outer wall of the elastically deformable layer, the sealing rib extending around the through hole in an axial direction and a circumferential direction of the sealing gasket.

7. The electronic water valve of claim 6, wherein the sealing gasket defines a break extending axially along the sealing gasket, the seal rib being disposed on opposite sides of the break.

8. The electronic water valve of claim 7, wherein the sealing rib is serrated.

9. The electronic water valve of claim 5, wherein the inner wall of the valve housing defines a protrusion, and the resilient deformable layer defines an opening into which the protrusion extends.

10. The electronic water valve of claim 5, wherein the low friction layer is a polytetrafluoroethylene layer.

11. The electronic water valve of claim 5, wherein the elastically deformable layer is an ethylene propylene diene monomer layer.

12. A thermal management system comprising an electronic water valve as claimed in any of claims 1 to 11.

13. A vehicle comprising the thermal management system of claim 12.
