Second thought, can you wire a servo, and then attach it to the valves on the actuator? In theory, it would work if you had a large gear on the servo and a small on the valve knob, similar to the chain and sprocket for the camera mounts.
just my $.02

Yeah, my "ricer car" has them. It's called a bleeder valve. You can get them from any major pnumatics components distributor.
