Valve assembly

Abstract

A multi-way valve assembly includes a valve housing having a plurality of fluid ports, a first valve member having one or more first flow channels defined therethrough and a first shaft, rotation of which causes rotation of the first valve member relative to the housing, the first valve member defining a cavity, and a second valve member arranged within the cavity of the first valve member and having one or more second flow channels defined therethrough and a second shaft. Rotation of the second shaft causes rotation of the second valve member relative to the housing. The assembly also includes a locking mechanism configured to, in a locked position, cause the second valve member to rotate with the first valve member relative to the housing and, in an unlocked position, to permit the second valve member to rotate relative to the first valve member and the housing.
