Abstract: A flow regulation control valve for regulating volume flows in pipelines including valve housing with a flow chamber, a control or shut-off member arranged in the flow chamber for setting a desired flow state through the valve, at least one sensor arranged in the vicinity of the flow chamber of the valve housing for sensing a characteristic value of the flow through the flow chamber, an electronic data store or memory for storing specific characteristic values of the housing of the flow regulation control valve, and an evaluation unit which is connected to the sensor and determines the volume flow from the values measured by the sensor with reference to the characteristic values of the valve stored in the data store.

Abstract: An extremely short lift valve comprising a casing with end faces located on a pipeline axis, wherein a separating surface with a valve seat is obliquely fitted in between the end faces of the casing.

Abstract: The invention concerns a tap fitting in which the gap between the tap spindle and the spindle lead-in in the housing is sealed off by means of a bellows-type seal. The end of the seal nearest the housing is connected to a sleeve which is sealingly mounted in the housing.
