1. A system, comprising:
a first controllable valve configured to output a first control pressure on one or more first pressure control lines;
a second controllable valve configured to output a second control pressure on one or more second pressure control lines;
a first shutoff valve in fluid communication with the first controllable valve via the one or more first pressure control lines, wherein the first shutoff valve is connected to one or more first pressure output lines, wherein the first shutoff valve is configured to move between:
a first valve open position such that the first shutoff valve is configured to fluidly communicate the one or more first pressure control lines with a first functional system via the one or more first pressure output lines; and
a first valve closed position such that the first shutoff valve is configured to restrict fluid communication of the one or more first pressure control lines with the first functional system via the one or more first pressure output lines;
a second shutoff valve in fluid communication with the second controllable valve via the one or more second pressure control lines, wherein the second shutoff valve is connected to one or more second pressure output lines, wherein the second shutoff valve is configured to move between:
a second valve open position such that the second shutoff valve is configured to fluidly communicate the one or more second pressure control lines with a second functional system via the one or more second pressure output lines; and
a second valve closed position such that the second shutoff valve is configured to restrict fluid communication of the one or more second pressure control lines with the second functional system via the one or more second pressure output lines; and
a transfer valve in fluid communication between the one or more first pressure output lines and the one or more second pressure output lines, wherein the transfer valve is configured to move between:
a first transfer valve position wherein the transfer valve is configured to restrict fluid communication between the one or more first pressure output lines and the one or more second pressure output lines; and
a second transfer valve position wherein the transfer valve is configured to fluidly communicate the one or more first pressure output lines with the one or more second pressure output lines.
