Fluid valve and fluid connection system

A fluid valve and fluid connection system comprising

• a housing having a receiving chamber with a first internal connection element and with a first external connection element,
• a first movable valve element arranged in the receiving chamber, and
• an actuating element, which has a fluid communication system with a second internal connection element and with a second external connection element,
• wherein the first internal connection element cooperates with the second internal connection element and the valve element to open or to block a fluid connection between the first and the second external connection elements,
• wherein the actuating element comprises at least one arm, wherein the at least one arm has at least one radially inwardly oriented protrusion, and wherein the housing comprises at least two grooves formed in a housing wall that are complimentary to the at least one radially inwardly oriented protrusion, wherein the grooves are arranged spaced apart from one another in the axial direction of the housing,
• wherein the actuating element is configured to be movable relative to the housing between a first position and a second position, wherein in the first position the fluid connection between the first and the second external connection elements is blocked, wherein in the first position the at least one arm is arranged such that the at least one radially inwardly oriented protrusion engages with a first groove associated with the first position, wherein in the second position the fluid connection between the first and the second external connection elements is open, wherein in the second position the at least one arm is arranged such that the at least one radially inwardly oriented protrusion engages with a second groove associated with the second position.
