OVERVIEW

Marshall Excelsior MEGR-1232-BBF Excela-Flo Compact Integral Two-Stage Regulator

The Marshall Excelsior MEGR-1232-BBF is a high-efficiency, compact integral two-stage regulator designed to meet the rigorous demands of modern propane applications. Part of the renowned Excela-Flo series, this regulator is engineered to combine the functions of both a high-pressure first-stage regulator and a low-pressure second-stage regulator into a single, streamlined unit. This integration not only saves space but also reduces the number of potential leak points in a gas system, making it a preferred choice for safety-conscious installations.

Designed primarily for Type I (integral) applications, the MEGR-1232-BBF is perfectly suited for recreational vehicles (RVs), small cabins, outdoor kitchens, and other domestic setups where tank pressure needs to be reduced to a safe, usable working pressure for appliances. The unit accepts full tank pressure (up to 250 PSI) through its 1/4-inch FNPT inlet and steps it down to an intermediate pressure of approximately 10 PSI within the first stage. The second stage then precisely regulates this down to a standard 11-inch water column (W.C.) outlet pressure, which is delivered through the 1/2-inch FNPT outlet.

With a robust capacity of 225,000 BTU/hr, this regulator can easily support multiple appliances simultaneously, such as a stove, furnace, and water heater, provided the total load does not exceed the rated capacity. The outlet pressure is adjustable within a range of 9.5 to 13 inches W.C., allowing technicians to fine-tune the system based on specific line length and appliance requirements. Constructed from die-cast aluminum and finished with a durable powder coat, the MEGR-1232-BBF is built to withstand harsh outdoor environments while maintaining reliable performance.

FAQ

A single-stage regulator reduces tank pressure to appliance pressure in one step, which can lead to fluctuating pressure as the tank empties. A two-stage regulator, like the MEGR-1232, reduces pressure in two steps (tank to ~10 PSI, then to 11" WC), providing a much more consistent flow and safer operation regardless of tank level.

The MEGR-1232-BBF features a 1/4-inch Female NPT inlet and a 1/2-inch Female NPT outlet. You will likely need a pigtail hose to connect the inlet to your propane cylinder.

This regulator has a capacity of 225,000 BTU/hr. This is generally sufficient for an RV with a furnace, water heater, stove, and refrigerator running simultaneously.

Yes, the outlet pressure is adjustable between 9.5 and 13 inches of water column. However, it comes factory preset to the standard 11 inches W.C. and should only be adjusted by a qualified technician using a manometer.

Yes, the MEGR-1232 series is specifically designed for RV and small domestic applications. It is a common replacement for standard vertical or horizontal RV regulators.

The MEGR-1232-BBF typically does not include a separate mounting bracket in the box, though it has mounting holes on the body. Check the specific 'includes' section or purchase a bracket separately if needed.

It should be mounted with the vent pointing downward (or protected) to prevent water and debris from entering the regulator, which could cause internal damage or freezing.

In Marshall Excelsior part numbers, suffixes like 'BBF' often refer to packaging configurations (e.g., bulk pack vs. retail pack) or specific vent orientations/fittings. The core performance specifications remain the same as the base MEGR-1232 model.
