Pro-Flo ADS Operation Menu

The Unbalanced Spool The large end of the air valve spool has Intermittent Air Pressure Constant Air Pressure The large end of the air valve spool has more surface area than the small end. Force = pressure x area Menu

Key take-away when working on the Pro-Flo air distribution system: Pilot spool must be removed and installed from the notched end Air valve spool must not be out of the air valve body for more than a few minutes for cleaning, inspection and re-lubing (the seals are ‘energized’ and will expand) Pilot spool must not be out of the pilot sleeve for more than a few minutes for cleaning, inspection and re-lubing (the seals are ‘energized’ and will expand) Menu
