Description
Axial Flow LincolnLog design utilizes a tortuous path to distribute pressure drop along the axis of the plug. The axial stages throttle in unison as the plug strokes, maintaining staging ratios at all lift points. Velocity and pressure drop are controlled, thus eliminating cavitation and the resulting trim damage. This valve is highly effective in pump recirculation and high pressure liquid letdown applications, including those found in Hydrotreater processes.
