Abstract
Cette vanne est conçue de façon à éviter tout phénomène de cavitation particulièrement néfaste dans des applications à des circuits haute pression. A cet effet, elle comporte en série avec le passage délimité entre l'obturateur 16 et son siège 15 plusieurs étages de détente constitués par des passages 19 et des cavités 20. Ces passages et cavités sont délimités par des éléments annulaires 18 entourant une tige de manoeuvre 17 de forme tronconique.
