\n- L'ensemble de grande vanne a une structure novatrice et adopte un \u00e9tranglement par manchon. Contr\u00f4le efficace de la vitesse d'\u00e9coulement autour de 30 m\/s
\n- La surface d'\u00e9tranglement est s\u00e9par\u00e9e de la surface d'\u00e9tanch\u00e9it\u00e9 du si\u00e8ge de vanne, ce qui prot\u00e8ge efficacement la surface d'\u00e9tanch\u00e9it\u00e9, offre de bonnes performances d'\u00e9tanch\u00e9it\u00e9 et une longue dur\u00e9e de vie. Les composants internes sont en acier inoxydable \u00e0 haute r\u00e9sistance
\n- Le noyau de vanne adopte une structure \u00e9quilibr\u00e9e en pression pour r\u00e9duire la force d\u00e9s\u00e9quilibr\u00e9e du fluide agissant sur le noyau de visualisation<\/p>","protected":false},"excerpt":{"rendered":"
