Caract\u00e9ristiques :<\/p>\n
-Corps de vanne forg\u00e9 type angulaire, type Z
\n-Le fluide est d\u00e9pressuris\u00e9 \u00e9tape par \u00e9tape, et la direction du fluide change continuellement. Augmente la r\u00e9sistance \u00e0 l'\u00e9coulement, contr\u00f4le le d\u00e9bit et pr\u00e9vient les dommages par cavitation du fluide. La diff\u00e9rence de pression admissible dans la vanne est de 25 MPa
\n- Conception d'\u00e9tranglement multi-\u00e9tages
\n-La surface de \u00e9tranglement est s\u00e9par\u00e9e de la surface d'\u00e9tanch\u00e9it\u00e9, et la surface est durcie avec une conception anti-grippage pour particules solides<\/p>","protected":false},"excerpt":{"rendered":"
