Zusammenfassung: | A system can include a first controllable valve (102) configured to output a first control pressure on one or more first pressure control lines, a second controllable valve (106) configured to output a second control pressure on one or more second pressure control lines (108a, 108b), and a valve assembly. The valve assembly can be configured to direct the first control pressure to a first functional system and the second control pressure to a second functional system in a first state, direct the first control pressure to both of the first functional system and the second functional system in a second state, and direct the second control pressure to both of the first functional system and the second functional system in a third state. |
