The valve according to the present invention, in particular, a fuel injector, is characterized by having an improved sealing at its spray-side end. The fuel injector () includes an excitable actuator () for actuating a valve closing body (), which together with a valve seat surface () formed on a valve seat body () forms a seal seat, and spray openings () formed downstream of the valve seat surface (), and a valve seat support (), which accommodates the valve seat body (), forms a portion of a valve housing () and is fixedly connected to the valve seat body (). A plastically deformable sealing element () is introduced into an annular gap () between the valve seat support () and the valve seat body () to avoid corrosion and damage of a weld seam (). The fuel injector is particularly suitable for directly injecting fuel into a combustion chamber of a mixture-compressing spark ignition internal combustion engine.
