Abstract

Cette invention concerne un ensemble vanne (35) agencé dans une conduite de fluide (342, 343). Ledit ensemble vanne (35) comprend deux ou plusieurs vannes actionnées par fluide (351, 352, 353). Chacune desdites vannes comprend un tiroir de vanne (355) disposé de manière coaxiale dans un boîtier de vanne (354). Un dispositif de précontrainte (356) est agencé de sorte à pouvoir assurer un déplacement axial du tiroir de vanne (355) dans une première direction, une pression de fluide assurant le déplacement dans le sens opposé. Un dispositif de commande de tiroir (357) est doté d'un rail de guidage (357a) conçu pour pouvoir recevoir un dispositif de guidage (357c). Un rail de guidage (357a) et un dispositif de guidage (357c) sont disposés dans le boîtier de vanne (354) et le tiroir de vanne (355). Une configuration de position des vannes (351, 352, 353) comprend au moins les positions fermée (0) et entièrement ouverte (1). Les vannes (351, 352, 353) sont reliées à une ligne de commande commune des vannes (342). La configuration de position pour une première vanne (351) diffère de celle d'au moins une autre des vannes (352, 353).
