Testable pneumatic control assemblies and related systems and methods

A system comprising:

• a pneumatically actuated valve;
• a compressed air supply;
• a vent;
• and
• a pneumatic control assembly including:
• first, second, and third parallel supply channels between the pneumatically actuated valve and the compressed air supply;
• first, second, and third parallel vent channels between the pneumatically actuated valve and the vent;
• first, second, third, fourth, fifth, and sixth logic valves, the first and sixth logic valves each disposed in both the first parallel supply channel and the first parallel vent channel, the second and third logic valves each disposed in both the second parallel supply channel and the second parallel vent channel, the fourth and fifth logic valves each disposed in both the third parallel supply channel and the third parallel vent channel, the first, second, third, fourth, fifth, and sixth logic valves to control the flow of compressed air between the pneumatically actuated valve, the compressed air supply, and the vent;
• a first solenoid valve to control air flow from the compressed air supply to a first pilot channel fluidly coupled to the first and second logic valves;
• a second solenoid valve to control air flow from the compressed air supply to a second pilot channel fluidly coupled to the third and fourth logic valves;
• and
• a third solenoid valve to control air flow from the compressed air supply to a third pilot channel fluidly coupled to the fifth and sixth logic valves.

A non-transitory computer readable storage medium comprising computer readable instructions that, when executed, cause at least one processor to at least:

• energize first, second, and third solenoid valves of a pneumatic control assembly, the pneumatic control assembly including:
• first, second, and third parallel supply channels between a compressed air supply and a valve header;
• first, second, and third parallel vent channels between a vent and the valve header;
• first, second, third, fourth, fifth, and sixth logic valves, the first and sixth logic valves each disposed in both the first parallel supply channel and the first parallel vent channel, the second and third logic valves each disposed in both the second parallel supply channel and the second parallel vent channel, and the fourth and fifth logic valves each disposed in both the third parallel supply channel and the third parallel vent channel, wherein the first solenoid valve is to control the first and second logic valves, the second solenoid valve is to control the third and fourth logic valves, and the third solenoid valve is to control the fifth and sixth logic valves;
• de-energize the first solenoid valve while the second and third solenoid valves are energized, wherein, while the second and third solenoid valves are energized, the third parallel supply channel is open between the compressed air supply and the valve header;
• and
• determine, after the first solenoid valve is de-energized, whether the first solenoid valve moved from a first position to a second position.
