Abstract
A system can include a first controllable valve, a second controllable valve, a transfer valve, and a transfer control system. The first controllable valve can be configured to output a control pressure on one or more first pressure control lines. The second controllable valve can be configured to output a control pressure on one or more second pressure control lines. The transfer valve can be in fluid communication with the first controllable valve and the second controllable valve. The transfer valve can be configured to move between a first position, a second position, and a third position.
Claims20
A system, comprising:
- 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, wherein the transfer valve is configured to move between a first position, a second position, and a third position, wherein the transfer valve is configured to:
- fluidly communicate the one or more first pressure control lines to a first functional system and the one or more second pressure control lines to a second functional system in the first position;
- fluidly communicate the one or more second pressure control lines to the first functional system and the second functional system in the second position;
- and
- fluidly communicate the one or more first pressure control lines to the first functional system and the second functional system in the third position;
- and
- a transfer control system configured to control a position of the transfer valve between the first, second, and third position.
