The invention relates to a fluid control value, such as an umbrella valve (40), to be inserted in a valve housing (140), said valve comprising a sealing element (44) having a sealing surface and projecting in a radial direction for sealing one or more fluid openings (145) in said valve housing, which sealing element is responsive to fluid pressure to open and close to control the fluid flow through the fluid openings. 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.
