Abstract:
1. A valve arrangement adapted for mixing together at least two media, wherein said valve arrangement includes a first inlet and a first valve means for a first medium, and a second inlet and a second valve means for a second medium, wherein a movement of a valve body of a first valve means from and towards a first valve seat, and movement of the valve body of a second valve means from and towards a second valve seat are controlled mutually so that when a flow of said first medium through the first valve means increases the flow of the second medium through the second valve means will decrease, and vice versa, and wherein said first and second valve bodies are formed as a rod-like element, wherein said first valve seat and the second valve seat are formed in one and the same valve housing that comprises at least two parts; characterised in that an intermediate expanded part of said rod-like element and an inner expanded cavity in said housing are each provided with a threaded portion; in that said intermediate part of said rod-like element is provided with an external thread corresponding to said threaded portion; and in that one end-part of said rod-like element extends beyond said valve housing and is used for rotating said element.
