FIELD: machine building.
SUBSTANCE: group of inventions relates to a valve for controlling a fluid and to a method of manufacturing a valve for controlling a fluid. Method comprising a valve housing with a central part and with one, two or more connection ends extending away from the central part. Inside of the central part there is a valve body, for example with a through-opening. Valve body is arranged in a valve seat and is connected to a valve spindle, which is arranged in a spindle guide stub on the valve housing. Manufacturing of the spindle stub includes the following steps: providing a plate-shaped workpiece; providing plastic deformation of the plate-shaped workpiece in the form of a collar on the plate-shaped workpiece, whereby a spindle guide stub is formed such that the spindle guide stub has a collar along its lower edge and a cutout in the upper surface of the spindle guide stub.
EFFECT: preventing crevice corrosion in the area of connection between the spindle guide stub and the valve housing.
