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).
