Marshall Excelsior Co. Gas Cylinder Pressure Regulator

Marshall Excelsior Co. Gas Cylinder Pressure Regulators

When it comes to safely managing LP gas flow from cylinders, few names carry more weight than Marshall Excelsior Company (MEC). Founded in 1976 and headquartered in Marshall, Michigan, MEC has spent decades engineering precision gas control equipment trusted in domestic, recreational, and industrial settings around the world. Their gas cylinder pressure regulators represent the core of that expertise — built to reduce high cylinder pressures to safe, usable levels for grills, RVs, heaters, generators, and more.

A Regulator for Every Application

MEC's cylinder regulator lineup is notably broad, covering the full spectrum of pressure regulation stages and configurations. Key product families include:

• Single-Stage Regulators — Models like the MEGR-218 and MEGR-230 are compact, lightweight options designed for portable and outdoor cooking applications, accepting POL or QCC connections and rated up to 140,000 BTU/hr.
• Two-Stage Regulators — The Excela-Flo MEGR-298 and high-capacity compact two-stage models deliver precise pressure reduction in two steps, handling up to 250 PSI inlet pressure and outputting up to 175,000 BTU/hr — ideal for RVs and residential appliances.
• Second-Stage Regulators — Models such as the 1222 and 1622 series reduce output from first-stage regulators (typically 10 PSI) down to 11" W.C. or 2 PSI for final delivery to appliances.
• Automatic Changeover Regulators — Designed to switch automatically from an empty primary cylinder to a reserve cylinder without interrupting gas supply, keeping systems running continuously in two-cylinder setups.
• High-Pressure Adjustable Regulators — The MEGR-6120 series (available in 0–30 PSI and 0–60 PSI variants) provides adjustable outlet pressure in a die-cast aluminum body, suited for applications requiring higher working pressures.

What Sets MEC Regulators Apart

MEC's regulators are engineered under rigorous quality standards and many carry Underwriters Laboratories (UL) and Canadian Gas Association (CGA) approvals — a critical consideration for any safety-critical gas application. The company backs its regulator products with a 5-year warranty and an impressive 25-year regulator service life, reflecting confidence in the durability of their designs. Bodies are typically constructed from zinc die-cast with powder-coated finishes to resist corrosion in demanding outdoor environments.

MEC regulators are widely used across portable camping setups, RV propane systems, residential heating, and light commercial installations. Whether you need a simple single-stage unit for a backyard grill or a robust two-stage system for a full RV propane circuit, the MEC catalog covers it.
