Mode de fonctionnement

La vanne à contrôle combine les caractéristiques fonctionnelles d'un clapet anti-retour avec celles d'un soufflet étanche robinet à soupape. Une seule vanne est nécessaire dans une section où, auparavant, deux vannes devaient être utilisées. Si la tige de valve est en position ouverte (main roue en position haute), la vanne fonctionne comme un clapet anti-retour classique; le support peut se déplacer dans la direction d'écoulement; le bouchon se ferme en cas de refoulement. bouchon à ressort maintient la soupape en position fermée de telle sorte que la soupape peut être monté dans toute position. Si la tige de valve est en position fermée (main roue en position basse), la soupape fonctionne comme un robinet d'arrêt conventionnel; le bouchon reste fermé avec un débit de toutes les directions.
