Cavagna Kosan 528B automatic changeover ensures continuous gas flow, automatically changing the gas withdrawal from the empty “service” cylinder to the full “reserve” one. The full-empty indicator incorporated into the bonnet of the automatic changeover indicates the exhaustion status of the “service” cylinder. The indicator color changes from green to red, when the “service” cylinder is exhausted. The rotation of the automatic changeover handle to the full “reserve” cylinder restores the green color on the indicator.

Allows removal of empty cylinder for refill without interrupting propane supply.

Normally used on RV's with a two tank hookup.
