<p>A three-way diverter valve comprising a rotatable valve member (19) to which are mounted a number of sealing faces, each face being adapted to seal against one of the inlet (7a,7b) or outlet (9a,9b) of one of the paths the member (19) being movable between a first position in which both the inlet and outlet of a first path are sealed, and both the inlet and outlet of the second path are open for fluid to flow therethrough, and a second position in which both the inlet (7a,7b) and outlet (9a,9b) of the first path are open for fluid to flow therethrough and both the inlet and outlet of the second path are sealed, movement of the member (19) effecting sealing or opening of the inlet (7a,7b) and outlet (9a,9b) of each flow path substantially simultaenously, both paths being at least partially open for fluid to flow therethrough when the member (19) is between the first and second positions. <IMAGE></p> |
