Abstract

Valvola per conduttore di fluidi del tipo comprendente una sfera d'intercettazione (8) dotata di condotto passante (9) e anelli di tenuta (14, 15) interposti tra detta sfera e le condutture (2', 3') di passaggio del fluido in cui detto condotto passante (9) della sfera (8) è disposto con asse longitudinale spostato verso valle rispetto all'asse di rotazione della sfera (8), quando questa si trova ruotata in posizione di intercettazione, la distanza relativa tra longitudinale del condotto (9) e asse di rotazione della sfera (8) essendo tale che le aperture (9a) di monte del condotto (9) risultino sempre chiuse prima che le aperture di valle (9b) transitino sugli anelli di tenuta (15) di valle sia in chiusura sia in apertura della valvola.
