Features

1.Axial Flow LincolnLog™ design with tortuous flow path to distribute pressure drop along the plug axis

2.Multi-stage axial throttling at all plug lift positions to maintain stable staging ratios

3.Controlled flow velocity and pressure drop to prevent cavitation and trim damage

4.Stable and predictable throttling performance across operating range

5.Ideal for pump recirculation and high-pressure liquid letdown services

6.Suitable for hydrotreater and other high-pressure process applications
