A system includes a first pressure-adjusting device positioned in a first line and a second pressure-adjusting device positioned in a second line. The first pressure-adjusting device is actuated solely via a first pneumatic signal output from a first pilot valve to control a downstream pressure in the first line. The second pressure-adjusting device is actuated via the first pneumatic signal in a first mode of operation, and is actuated via a second pneumatic signal output from a second pilot valve in a second mode of operation to control a downstream pressure in the second line.
