Interface for a valve for a cryogenic fluid duct

An assembly comprising a duct for passing a flow of cryogenic fluid and a valve adapted to shut said duct selectively;

• the assembly being characterized in that the duct includes an interface for inserting the valve, the interface forming an internal abutment inside the duct and an external abutment outside the duct;
• the valve being configured so as to be removably inserted into said insertion interface by sliding, the valve comprising a valve body presenting a first end and a second end, the valve body being adapted to be removably bolted in said insertion interface so that the first end and the second end come into abutment respectively against the internal abutment and against the external abutment of the duct, the assembly including an internal sealing element arranged between the internal abutment of the duct and the first end of the valve body, and an external sealing element arranged between the external abutment of the duct and the second end of the valve body;
• and
• wherein the valve body and/or the duct include(s) an index suitable for orienting the valve body while it is being inserted in the duct, and
• wherein said duct includes a first portion and a second portion relative to the valve, said first and second portions:
• not being in alignment with each other;
• not being perpendicular with each other;
• and
• forming a deflection in the flow of fluid in the duct,
• wherein the insertion interface is arranged in line with one of the first and second portions so that the valve is inserted in the duct in alignment with said first portion or said second portion.
