Suburban Mfg 523015 Low Capacity Automatic Changeover LP Propane Regulator

The Suburban Mfg 523015 Low Capacity Automatic Changeover Regulator is a single-stage LP propane regulator designed to deliver uninterrupted gas flow to RV appliances. It automatically switches from an empty service cylinder to a full reserve cylinder, eliminating the need for manual intervention and ensuring your appliances keep running without disruption.

A highly visible full/empty indicator clearly signals when a cylinder needs to be refilled, and the built-in back check valve allows the empty cylinder to be safely removed and refilled while the reserve cylinder remains in active service. An Overpressure Protection Device (OPD) limits environmental propane release to less than 2 PSI in the event of a regulator malfunction — well below the threshold mandated by UL Standard 144.
