Abstract: A valve and a method for producing a valve for regulating a fluid, having a valve housing with a central part and with two connection ends, the connection ends extending away from the central part, wherein internally of the central part there is arranged a valve body including at least a shutoff part and a through-flow part. The valve seat is arranged in the valve housing and resiliently bears against the valve body, a resilient structural part has a spring action that acts in a direction substantially parallel with the flow direction of the valve and has at least one annular flange part adapted for bearing on the valve body. The resilient valve seat includes a fixing member for mechanical fixing of the valve seat in the valve housing. The fixing member has a flange part fixed in the valve housing by plastic deformation.

Abstract: A valve and method for producing a valve for regulating a fluid, the valve including a valve housing with a central part and two connection ends, the connection ends extending away from the central part. Internally of the central part, there is arranged a valve body with a through-going aperture that is arranged in a valve seat and connected to a valve spindle, the valve spindle being arranged in a spindle guide stub on the valve housing. The valve housing is made from a plastically deformed tubular item and includes a collared spindle guide stub with at least one projection, the projection or projections extending in continuation of the spindle guide stub. This projection can be used as a lock ensuring that the valve spindle is retained in its intended position, and at the same time, such projections can form stops at the extreme positions of the valve body.
