Valve apparatus (10, 20) intended to regulate a fluid flow from a fluid network, the valve apparatus comprising: a. a body through which the fluid is intended to flow, configured to connect the valve apparatus (10, 20) to the fluid network; b. a gate positioned inside the body and configured to move between an open position in which the fluid is intended to flow through the body and a closed position in which the fluid is not intended to flow through the body; c. a stem extending along a first axis Z comprising an upper part and a lower part, the lower part being connected to the gate; the body comprising a cylindrical neck extending around the first axis Z and adapted to surround the stem, wherein the neck comprises an inner planar surface substantially perpendicular to the first axis Z and the inner planar surface is one of the at least one contact surface (32, 72) of the neck; a handle comprising a second circular rib positioned around the first axis Z, the second circular rib being configured to engage with the upper part of the stem and the neck;and wherein the body and the stem comprise a first abutment for the second circular rib of the handle in translation according to the first axis Z, the first abutment being configured so as to form a gap between the handle and the upper part of the stem, the first abutment being further configured to form at least one contact surface (32, 72, 73) with the second circular rib of the handle, and wherein the body comprises a second abutment for the handle in rotation according to the first axis Z, wherein the second circular rib of the handle comprises an inner surface configured to form a linear guideway of the upper part of the stem according to the first axis Z, so that a rotation of the handle around the first axis Z rotably moves the stem around the first axis Z relative to the body so as to move the gate between the open position and the closed position, and wherein the neck comprises an inner surface and an outer surface, the valve apparatus being characterised in that the handle comprises: a. a first circular rib positioned around the first axis Z, having an inner surface at least partially in contact with the outer surface of the neck of the body; and b. the second circular rib having an inner surface partially in contact with the upper part of the stem and an outer surface partially in contact with the inner surface of the neck of the body. a. a body through which the fluid is intended to flow, configured to connect the valve apparatus (10, 20) to the fluid network; b. a gate positioned inside the body and configured to move between an open position in which the fluid is intended to flow through the body and a closed position in which the fluid is not intended to flow through the body; c. a stem extending along a first axis Z comprising an upper part and a lower part, the lower part being connected to the gate; the body comprising a cylindrical neck extending around the first axis Z and adapted to surround the stem, wherein the neck comprises an inner planar surface substantially perpendicular to the first axis Z and the inner planar surface is one of the at least one contact surface (32, 72) of the neck; a handle comprising a second circular rib positioned around the first axis Z, the second circular rib being configured to engage with the upper part of the stem and the neck;and wherein the body and the stem comprise a first abutment for the second circular rib of the handle in translation according to the first axis Z, the first abutment being configured so as to form a gap between the handle and the upper part of the stem, the first abutment being further configured to form at least one contact surface (32, 72, 73) with the second circular rib of the handle, and wherein the body comprises a second abutment for the handle in rotation according to the first axis Z, wherein the second circular rib of the handle comprises an inner surface configured to form a linear guideway of the upper part of the stem according to the first axis Z, so that a rotation of the handle around the first axis Z rotably moves the stem around the first axis Z relative to the body so as to move the gate between the open position and the closed position, and wherein the neck comprises an inner surface and an outer surface, the valve apparatus being characterised in that the handle comprises: a. a first circular rib positioned around the first axis Z, having an inner surface at least partially in contact with the outer surface of the neck of the body; and b. the second circular rib having an inner surface partially in contact with the upper part of the stem and an outer surface partially in contact with the inner surface of the neck of the body. a. a first circular rib positioned around the first axis Z, having an inner surface at least partially in contact with the outer surface of the neck of the body; and b. the second circular rib having an inner surface partially in contact with the upper part of the stem and an outer surface partially in contact with the inner surface of the neck of the body.
