Thanks again for you help, my problem was understanding where the air releases to when the solenoid is closed. This particular one you show me will in fact allow air to pass though it and escape out of the cylinder once de-energized? (8077K11) and one last thing, how long will these things last being that the door is primarily shut most of the time, so this will be energized most of the time... i plan on installing an access pannel for future modifications/repairs. Thank you again!
