V202 CLAPET À PAPILLON
TVN V202 Le Clapet à Papillon est un clapet qui fonctionne à l’aide d’un contrepoids, préféré dans les tuyauteries où une fermeture plus rapide est requise. Grâce au contre-levier et au poids attaché à son axe, assure une ouverture douce en fonction de la vitesse du débit et maintient des temps de fermeture réduits lorsque le débit s’arrête.
Avec sa conception de papillon où le centre est décalé sur deux axes, cela conduit à une grande amélioration de la diminution des valeurs de couple de fonctionnement, en réduisant le frottement sur la zone d’étanchéité du papillon et en prolongeant la duré
