A system includes a pressure exchanger (PX) including a housing and configured to exchange pressure between a first fluid and a second fluid. The system further includes a bearing valve fluidly coupled to the housing of the PX and configured to provide the first fluid to the housing. The system further includes a controller to cause a first adjustment of a first flowrate of the first fluid into the PX based on a target flowrate of first fluid into the PX and the first flowrate. The controller is further to cause a second adjustment of a second flowrate of the second fluid into the PX based on the first flowrate and the second flowrate.
