A process control valve included a valve stem and a valve plug (34). The valve stem and the valve plug (34) are attached to one another by an arrangement that includes a locking pin (42) that passes through substantially aligned bores (44, 46) in the valve stem and the valve plug (34). The locking pin (42) is positively retained mechanically and prevented from extending outside of the bores (44, 46) in the valve stem and the valve plug (34).

L'invention concerne une vanne de commande de processus comprenant une tige de commande et une soupape (34). La tige de commande et la soupape (34) sont assemblées mutuellement au moyen d'un système comprenant une goupille (42) de verrouillage enfilée à travers des orifices (44, 46) sensiblement alignés formés dans la tige de commande et dans la soupape (34). La goupille (42) de verrouillage est retenue par blocage mécanique, et empêchée de s'avancer hors des orifices (44, 46) formés dans la tige de commande et dans la soupape (34).
