Abstract
A system can include a first controllable valve configured to output a control pressure on one or more first pressure control lines, a second controllable valve configured to output a control pressure on one or more second pressure control lines, a transfer valve in fluid communication with the first controllable valve and the second controllable valve, and a hydraulic centering system operatively associated with and/or forming part of the transfer valve. The transfer valve can be configured to move between a first position, a second position, and a third position. The hydraulic centering system can be configured to maintain the transfer valve in the first position.
