A uniform shear valve for an extruder machine includes a body having a generally annular wall that defines an interior area extending along a longitudinal axis thereof. The interior area extends between an inlet proximate a first end of the body and a second end of the body. The second end is opposite the first end. The body has a first bore extending through the wall along a traverse axis substantially perpendicular to the longitudinal axis at a first position and second position. A flow control member is sealingly and slidingly positioned partially in the first bore at the first position and extends out of the body. The flow control member defines a first seat on an end thereof. An outlet is located in the first bore at the second position. A second seat is positioned proximate the outlet and is concentric with the first seat along the traverse axis. A uniform flow area is defined by a gap between the first seat and the second seat. |
