1. A valve assembly for a reciprocating downhole pump comprising:
a flow cage comprising:
a housing having a longitudinal axis and defining an axial bore therethrough; and
a tubular insert received within the axial bore, the tubular insert defining an axial flow passage, wherein the tubular insert comprises:
an upper insert section comprising an upper plurality of helical side ribs defining an upper plurality of helical side openings to the axial flow passage, the upper insert section further comprising an upper stop; and
a lower insert section comprising a lower plurality of helical side ribs defining a lower plurality of helical side openings to the axial flow passage, the lower insert section being positioned below the upper insert section, and wherein the lower insert section lacks a stop;
an annular valve seat received within the axial bore and positioned below the tubular insert; and
an elongated sealing member positioned above the annular valve seat and at least partially received within the axial flow passage of the tubular insert, wherein the elongated sealing member is movable between a closed position, in which the elongated sealing member engages the annular valve seat, and an open position, in which the elongated sealing member is displaced from the annular valve seat.
