Then you need to adjust them or replace them, you can close the valves completely and let no air pass through at all on several of the types listed.

If your cylinders are retracting due to gravity (and I am assuming a loss of air pressure), you may not have enough storage. How many/what size air tanks do you have? Are they on the high pressure side or the working pressure side? Have you done thorough leak checks and how quickly does your pressure drop?
