A flow control valve includes an inlet, an outlet, and defines a fluid flow path. A valve seat is disposed within a valve body, and a valve plug in the valve body is surrounded by a cage. An exterior surface of the valve plug includes a plurality of notch sets, each notch set spaced apart from an adjacent notch set along the longitudinal axis, and the cage is disposed within the valve body and arranged to retain the valve seat, with an interior of the cage including a plurality of annular recesses. The annular recesses are spaced apart along the longitudinal axis, and the cage includes a plurality of apertures forming a portion of the fluid flow path. The notch sets and the recesses are arranged to form a plurality of turns in the fluid flow path when the valve plug is shifted toward the open position.

A valve plug assembly includes a support member having a support member body having a first end and a second end. A stem bore adapted to receive a valve stem may extend axially inward from the second end, and a mating protrusion may extend axially outward from the first end. The valve plug assembly also includes a plug tip having a first end and a second end, and a plug surface adapted to engage a valve seat is disposed adjacent to the first end. A mating bore may extend axially inward from the second end, and the mating protrusion may be received into the mating bore such that a threaded portion of the mating protrusion engages a threaded portion of the mating bore. Additionally, an adhesive bonds the threaded portion of the mating protrusion to the threaded portion of the mating bore.
