Seems like I accidentally changed the name instead of pin number when making the ADUM2201 symbol. The correct pin number and name of the missing pin are 13 and "A-IN". Pin 11 is no-connect. Will get that fixed the next time I have Altium running.

A solenoid is a type of actuator. Others used for pneumatic control would be servo valves, two-stage valves with a pilot pressure, and probably some others I haven't heard of. Also not all actuators are accurate or allow a continuum of positions.

More complex control systems using valves requiring automatic control based on an external input require an actuator. An actuator will stroke the valve depending on its input and set-up, allowing the valve to be positioned accurately, and allowing control over a variety of requirements.
