L'action \u00e0 deux positions de la vanne est principalement utilis\u00e9e dans le syst\u00e8me d'alimentation en eau des grands groupes \u00e9lectrog\u00e8nes. C'est un \u00e9quipement important pour pr\u00e9venir la vaporisation de la pompe d'alimentation en eau de chaudi\u00e8re, et c'est aussi l'un des r\u00e9glages cl\u00e9s dans la centrale \u00e9lectrique. Elle est \u00e9galement couramment utilis\u00e9e dans le p\u00e9trole, la chimie et d'autres occasions de contr\u00f4le \u00e0 deux positions avec une forte diff\u00e9rence de pression.<\/p>\n
