If your Valve looks wider than the pictures, then the most likely explanation is tha the Brass Bush has come away with the valve, in which case you will need to order a brass bush part if you cannot separate.  There are two bushes used with this valve. The 3408r is 36mm diameter and the 3409R  is 30mm in diameter.
