A non-return valve assembly for a high-pressure fuel injection system is disclosed. The valve comprises a valve chamber defined in part by a first body and in part by a second body and defining a valve chamber wall, an inlet passage formed in the first body and opening into the valve chamber at a valve seat defined by the first body, an outlet passage, and a valve ball received within the valve chamber and engageable with the valve seat so as to interrupt fluid flow from the outlet passage to the inlet passage through the valve chamber. The valve chamber wall comprises a plurality of guide portions to guide the valve ball in substantially linear movement within the valve chamber.
