Zusammenfassung:	A fluid control valve includes a valve body, having a fluid inlet passage 32, and a fluid outlet passage 34 . The control valve further includes a valve stem 44 and a one-piece self-retaining bushing 52a that guides the valve stem. A shouldered portion 58a on the one-piece self retaining bushing 52a is adapted to engage with a valve component 46. L'invention concerne une vanne de régulation comprenant un corps pourvu d'un passage d'admission de fluide (32) et d'un passage d'évacuation de fluide (34). Cette vanne de régulation comprend également une tige de manoeuvre (44) et une bague autostatique monobloc (52a) qui guide la tige de manoeuvre. Une partie à épaulement (58a) située sur la bague autostatique monobloc (52a) est conçue pour venir en butée contre un composant de la vanne (46).
