  "abstract": "The invention relates to a device (D) for supporting and holding the gate of a valve during a maintenance operation. It comprises two identical tools ( 8 ), each comprising a plate ( 80 ) in the form of a half-disc delimited by a generally rectilinear edge ( 800 ) and a semi-circular edge ( 801 ), the upper surface ( 802 ) of which plate ( 80 ) has a first radius, while the lower surface thereof, parallel to the upper surface ( 802 ), has a second radius which is smaller than the first radius, thereby forming a semi-circular peripheral shoulder ( 804 ), a through-cut ( 81 ) being made in the thickness of the plate ( 80 ), which through-cut, seen from above, is inscribed in a rectangle and opens onto the generally rectilinear edge ( 800 ), the side wall ( 810 ) of this cut ( 81 ) which extends parallel to the generally rectilinear edge ( 800 ) being inclined and forming an acute angle with a line perpendicular to the upper surface ( 802 ).",
