A valve (100) comprising a valve body (124) defining a flow path (126), a seat (110) upon which a closure member (108) may rest for blocking an outlet port of the valve body, and a spacer (142) removably mounted in the valve body to provide at least one arresting surface against which the closure member (108) may abut when displaced in an open position by fluid pressure. The spacer prevents the closure member from frictionally contacting the inner surfaces of the valve body (124).
L'invention concerne une soupape (100) qui comprend un corps de soupape (124) délimitant un passage pour flux (126), un siège (110) sur lequel peut reposer l'élément de fermeture (108) pour bloquer un orifice de sortie du corps de soupape et un séparateur (142) monté amovible sur le corps de soupape (124) et servant à former au moins une surface d'arrêt contre laquelle bute l'élément de fermeture (108) lorsqu'il est déplacé en position d'ouverture par la pression du fluide. Le séparateur empêche l'élément de fermeture d'entrer en un contact par frottement avec les surfaces internes du corps de soupape.
