Claim 14:
15. A method for providing or repairing a turbomachine system comprising:
a valve arrangement, the valve arrangement comprising: a stationary element and a movable element, wherein the stationary element comprises a cavity, in which the movable element moves, wherein the movable element is moveable translationally along a first axis within the cavity of the stationary element, wherein the movable element comprises a piston element and a rod-shaped coupling element, wherein the piston element comprises an outer side parallel to the first axis, the valve arrangement being designed in such a way that a throughflow of a fluid flow between the stationary element and the outer side of the piston element is prevented, wherein the piston element comprises a contact edge which is suitable for making contact with a valve seat, wherein the piston element comprises a rear side opposite the contact edge, wherein the coupling element is fastened to the rear side of the piston element, wherein the contact edge is rounded and is suitable for providing a linear contact with the valve seat, wherein the contact edge is situated on a thickened portion of the piston element, wherein an inner diameter of the valve seat increases toward the piston body to form a convex rounded valve seat surface, and wherein the valve arrangement is configured to cause the contact edge to selectively abut the convex rounded seat surface to prevent the throughflow; and
a fluid flow control element comprising a fluid flow line and a fluid flow inlet opening comprising the valve seat within the fluid flow line, wherein the valve seat is suitable for making the contact with the contact edge of the valve arrangement;
the method comprising:
installing or repairing the valve arrangement or the fluid flow control element.
