Description

The new MEGR-253HP Excela-Flo Propane Regulator by Marshall Excelsior Company is a high-capacity two-stage automatic changeover regulator engineered for RV and mobile LP gas systems requiring superior flow performance.

Product Details

  • Designed for dual-cylinder RV setups, this regulator automatically switches propane supply from the empty service cylinder to the full reserve cylinder—ensuring uninterrupted gas flow to appliances. A clear green-to-red indicator provides an easy visual cue when the primary cylinder requires refilling.
  • With a first-stage capacity of 350,000 BTU and second-stage capacity of 200,000 BTU, this regulator delivers stable, consistent 11" WC outlet pressure under fluctuating demand conditions.
  • Built from die-cast zinc with a zinc powder-coated finish, and featuring an internal spring-loaded relief diaphragm, this vertical-mount regulator is constructed for durability, corrosion resistance, and long-term reliability in outdoor RV environments.
  • Also referenced under updated part number MERG-253HP.
