Valve for uranium hexafluoride storage tank

A valve for a uranium hexafluoride storage tank, comprising a valve body, the valve body delimiting a duct and having an inlet connector portion where an end of the duct opens, the inlet connector portion being intended to be connected to the uranium hexafluoride storage tank, and an outlet portion opposite the inlet connector portion, wherein the valve comprises:

• a fastener movably mounted on the inlet connector portion, the fastener removably securing the inlet connector portion to the uranium hexafluoride storage tank,
• an obturation member movable in rotation in the duct between a closing position in which the obturation member obturates the duct and an opening position in which the obturation member releases a passage through the duct,
• two seats interposed between the obturation member and the valve body, and
• a biasing spring providing a biasing force to hold the seats and the obturation member in bearing contact, and wherein
• the duct has a bent portion, the bent portion being arranged upstream the obturation member, between the inlet connector portion and the obturation member, wherein the fastener comprises an inner thread, the inner thread engaging an outer thread of the inlet connector portion.
