Marshall Excelsior Company

What Marshall Excelsior Company does

Marshall Excelsior Company (MEC), founded in 1976 in Marshall, Michigan by Jeffery Begg, designs and manufactures highly engineered flow control components for the liquefied petroleum gas (LPG) and anhydrous ammonia (NH3) industries. Its product portfolio spans pressure regulators, pressure relief valves and manifolds, internal combination valves, excess flow valves, emergency shutoff valves, bypass valves, float gauges, hose reels, swivels, fittings, adapters, and test/safety equipment organized under proprietary brands such as Excela-Wynd, Excela-Flo, Excela-Flange, Turbo-Flo, SENTINEL, Versa-Fill, and Accu-Max. Differentiated features include pilot-operated relief mechanisms, dielectric isolation inlets, integrated multi-function valves, and low-emission transfer equipment; products meet CGA, NFPA 58, ANSI, ASME, and UL certifications.

MEC generates revenue primarily through one-time hardware sales of flow control components and aftermarket replacement parts, sold via a global authorized distributor network (19+ US distributors plus partners across Latin America, Canada, and South Africa) and direct OEM relationships with vessel and system manufacturers. Pricing is quote-based with warranty terms up to 5 years standard, 10 years for products purchased after January 1, 2026, and 25-year regulator service life claims. In 2023, MEC generated approximately $120 million in revenue. The company was acquired by Dover Corporation in July 2024 for $395 million and now operates as part of OPW Global within Dover's Propane Energy Solutions segment, alongside the CPC-Cryolab, BASE Engineering, and Xanik brands.
