Abstract: The invention relates to a method for producing a metering valve (1) for a fluid, in particular for a liquid and/or gaseous fuel, comprising a preferably plate-shaped valve seat element (2) having at least one throughflow opening (3) for the liquid and/or gaseous fuel, a lift-movable valve disk (4) that sealingly interacts with the valve seat element (2) for releasing and closing the at least one throughflow opening (3), and a stroke stop element (5) having an annular stroke stop surface (6) for limiting the stroke of the valve disk (4). According to the invention, the stroke stop element (5) is axially pretensioned in the direction of a stroke adjustment ring (7) surrounding the valve disk (4). In order to finely adjust the stroke of the valve disk (4), the axial pretensioning force is altered, whereby the stroke stop element (5) is deformed. The invention further relates to a metering valve (1) for a fluid.

Abstract: The invention relates to an electromagnetically actuatable metering valve for liquids and/or gases, comprising: a valve housing (1); a valve seat element (2) which is connected to the valve housing (1) and in which at least one outlet opening (3) is formed; and a magnetic armature (4) which can move in a stroke-like manner relative to the valve seat element (2) and which is securely connected to a plate- or disc-shaped valve closing element (5) for opening and closing the at least one outlet opening (3) or which forms same; as well as a magnetic core (6) opposite the magnetic armature (4) at a working air gap (14) and at least one spring (7) pretensioning the magnetic armature (4) and the valve closing element (5) in the closing direction.

Abstract: A gas valve 1, in particular a dosing valve for a gaseous medium, having a valve seat body 3, which is arranged on a valve housing 2, and a closing body 7, which can perform a stroke motion relative to the valve seat body 3 and to an opening stroke stop 17 interacting with the valve housing 2. According to the invention, a gas valve 1 is provided which is improved as regards its durability. This is achieved by virtue of the fact that the gas valve 1 has an impact body which reduces the impact speed and/or impact energy of the closing body 7 on the valve seat body 3 and/or on the opening stroke stop 17.
