A METHOD OF MANUFACTURING A LABELLED FLUID CONTROL VALVE AND A LABELLED FLUID CONTROL VALVE

摘要

A labelled fluid control valve comprises a valve housing, a closure element (4) and a valve spindle. A label ring (36) is forged over an end part of the valve housing so as to leave permanent impressions on the label ring as well as on the valve housing. This presents useful label information and ensures that any replacement of the label will leave visible traces.
