Vanne à triple excentration cryogénique Vanessa série 30,000 avec actionneur manuel

Product Description

La vanne à triple excentration cryogénique Vanessa série 30,000 est une vanne pratiquement sans maintenance, dont l’étanchéité, le fonctionnement et la demande de couple ne sont pas affectés par les conditions cryogéniques et les variations de température importantes. La vanne est livrée complète avec un actionneur manuel, configurable en commande manuelle ou en réducteur.

Caractéristiques

Vanessa Series 30,000 Cryogenic Triple Offset Valve
