it needs to operate a solenoid for ~2 seconds which ... means that it stops listening for new requests - as the other comments point out you just need to restructure. Turn the solenoid on, remember when you did that, and check in the loop which is listening for new requests if the time is up to turn it off again.

Not sure if it will work for your case, but you can try using interrupt to quickly jump to some signal and back to your main loop. This is similar to concurrency in a web server, since Arduino cannot run things in parallel.

Then you need to start with the basics. Look at the BlinkWithoutDelay example to see how to write non-blocking code. I'll bet your sketch is littered with delay() calls. There is no place for delay() in a proper program, except for tiny (a millisecond or so) delays for timing purposes. Also, get to grips with the concept of the Finite State Machine (there are many resources and tutorials online).
