Abstract: A standing valve assembly comprises a flow cage, a ball seat, and a valve ball. The flow cage includes a cage body defining an axial fluid passage therethrough, and a bridge extending across the fluid passage. The cage body and the bridge collectively define a plurality of openings to the fluid passage. The valve ball is received between the bridge and the ball seat and is axially movable within the flow cage. The bridge has an upper face and defines at least one guide ramp in the upper face. Each guide ramp extends at a downward angle to a respective one of the plurality of openings.
