The chamber has a proximal chamber surface and a distal chamber surface being opposite to the proximal chamber surface. The valve further includes a fluid inlet, a fluid outlet, a valve rod and a valve plug. The valve plug and the valve rod are arranged to control fluid flow from the fluid inlet to the fluid outlet via the chamber. The valve further includes a valve insert arranged at least partly inside the chamber. The valve insert includes a proximal portion and at least two distal portions, and the valve plug is adapted to be guided through at least a part of the valve insert. At least one of the distal portions is resiliently arranged relative the proximal portion in order for the distal portions to be movable relative each other.
