A valve for controlling fluid flow that includes a valve body and a chamber arranged inside the valve body. 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.

Valve having a valve insert

A regulating valve for flow control of a medium in a heating or cooling system includes a valve body including an inlet connection, an outlet connection, and a valve neck in which a valve seat and a flow through opening are provided. In the valve neck, a complete valve trim and a valve hand wheel are provided. The valve body includes a first cone to determine the preset (Kvs-value) of the maximal flow through the complete regulating valve. The first cone has at least one opening for flowing through of the medium, where the design of the opening determines the regulating characteristic of the complete regulating valve, and where the Kvs-value of the valve is changed continuously, with maintained regulating characteristic. The first cone is arranged continuously, axially displaceable relative the valve seat, whereby selected parts of the opening of the first cone are shielded by the valve seat.
