The sealing element is provided with at least one recess (47) on the surface of the sealing element such that at least one sealing end (45) is defined on the sealing element extending between the recess and the periphery of the sealing element, said sealing end carrying the sealing surface. The fluid control valve according to the invention is an excellent pressure relieve valve allowing a large flow at a high opening pressure. |
