ABSTRACT:
A control valve apparatus couples pressurized fluid to first and second actuators using first and second double valves. The first double valve includes first and second crossover passages and first and second pilots. The second double valve includes third and fourth crossover passages and third and fourth pilots. A first interconnection couples the first crossover passage with the third pilot fluid inlet. A second interconnection couples the second crossover passage with the fourth pilot fluid inlet. A third interconnection couples the third crossover passage with the first pilot fluid inlet. A fourth interconnection couples the fourth crossover passage with the second pilot fluid inlet. Thus, operation of each pilot depends upon receiving pressurized fluid from the other double valve which is only present when the other double valve is not in a fault condition.
