Marshall Excelsior Co. Two-Stage Automatic Changeover LP Gas Regulator

The Marshall Excelsior Co. Two-Stage Automatic Changeover LP Gas Regulator (also called an auto changeover propane regulator) keeps LP gas flowing in dual-cylinder systems. When the service cylinder runs empty, it automatically switches vapor flow to the reserve cylinder, so gas service isn't interrupted. It suits RV, cabin and cottage propane setups.

Key Features:

• Automatic changeover: Redirects LP gas vapor flow from an empty service cylinder to a reserve cylinder without interrupting service.
• Visual indicator: A green indicator turns red when the service cylinder needs refilling.
• Two-stage regulation: Delivers consistent low-pressure output for appliances.
• Durable construction: Die-cast zinc bonnet and body, with a fabric-reinforced molded diaphragm and an O-ring bonnet/body seal.
• Built-in safety: Internal spring-loaded relief design.
• Compliance: The MEGR-253 series meets UL, RVIA and NFPA requirements.
• Made in the USA and backed by a limited 5-year warranty.

Marshall Excelsior's Excela-Flo regulators are built to give reliable, uninterrupted LP gas supply. Installation and work on a propane system should be done by a qualified person.
