Shouldn't be too difficult to retrofit either really.

why do they still use a tapered disc on a stick as a valve? Why not use the same principles (as a solenoid effectively) to control a rotating slot across the inlet/exhaust port? The amount of rotation could essentially open the port up more like a swivel ball does in a water valve.

Similar to proportional solenoids in process control.
Speed of actuation is probably the answer though.
