Abstract
A control valve assembly for an engine system having a turbocharger system. The control valve is configured to control the position of a turbine actuator and a compressor actuator by directing hydraulic fluid into the proper passages. The control valve assembly includes a hydraulic powered bypass valve that, when energized, can reduce flow restriction of the hydraulic fluid, and can increase the speed of actuation of the turbine actuator.
