\nV521 Vannes de r\u00e9gulation et de r\u00e9duction de la pression sont des vannes de commande \u00e0 commande hydraulique qui r\u00e9duisent une pression amont plus \u00e9lev\u00e9e dans le r\u00e9seau d’eau en une pression aval constante inf\u00e9rieure pr\u00e9d\u00e9finie souhait\u00e9e, et la maintiennent constante, ind\u00e9pendamment de la demande fluctuante ou de la pression amont variable. Lorsqu’il n’y a pas de d\u00e9bit dans le syst\u00e8me, il se ferme automatiquement et chaque fois que la valeur de pression amont de la vanne diminue en dessous de la valeur de pression aval ajust\u00e9e, elle s’ouvre compl\u00e8tement d’elle-m\u00eame. Dans les cas, la valeur de pression aval de la vanne augmente au-dessus de la valeur de pression aval ajust\u00e9e, elle se ferme compl\u00e8tement d’elle-m\u00eame.<\/p>\n
