Complementary fluidic valves and systems

A fluidic system comprising:

• a plurality of fluid-pressure sources;
• one or more fluid-pressure loads;
• and
• a fluidic valve comprising:
• a first inlet port, a second inlet port, and a control port, wherein at least one of the first inlet port, the second inlet port, or the control port are coupled to one of the plurality of fluid-pressure sources;
• one or more outlet ports, each of the one or more one or more outlet ports being coupled to a corresponding one of the one or more fluid-pressure loads;
• a first fluid channel configured to convey fluid from the first inlet port to at least one of the one or more outlet ports;
• a second fluid channel configured to convey fluid from the second inlet port to at least one of the one or more outlet ports;
• and
• a piston comprising:
• a first restricting gate transmission element configured to:
• block, when the piston is in a first position, the first fluid channel;
• and
• unblock, when the piston is in a second position, the first fluid channel;
• a second restricting gate transmission element configured to:
• block, when the piston is in the second position, the second fluid channel;
• and
• unblock, when the piston is in the first position, the second fluid channel;
• a first controlling gate transmission element configured to interface with a first control pressure from the control port, wherein the first control pressure, when applied to the first controlling gate transmission element, forces the piston towards the first position;
• and
• a second controlling gate transmission element configured to interface with a second control pressure, wherein the second control pressure, when applied to the second controlling gate transmission element, forces the piston towards the second position.
