Marshall Excelsior Company

Marshall Excelsior Company, headquartered in Marshall, Michigan has been providing innovative solutions to the LPG industry’s equipment needs for over 35 years. John Begg founded the company with a vision to build a design and manufacturing firm specializing in the highest quality LPG valves and connections with an unrivaled personal touch towards our customers. Today our family owned business has grown significantly since those early days now employing over one hundred phenomenal people in four facilities, all dedicated to fulfilling this vision of commitment to our customers. Our management team is committed to carrying this vision forward as we continue to focus on working hand in hand with our customers to develop products that meet the ever changing needs of the industry. Marshall Excelsior offers a full range of products that support LPG bulk plant, transport, delivery, dispensing and domestic applications. As we develop new products we are constantly striving to improve product functionality while taking the industry standards to a higher level of quality and performance without adding excessive cost.

This commitment has produced several new technologies in recent years like the Turbo-Flo LE Low Emission transfer system which provides the marketer with a great number of new safety features not found in current transfer valves while reducing fugitive product emissions by 99%. Our Smart Interlock technology that launched two years ago has quickly become an industry standard in preventing bobtail drive-offs and roll away during product transfer operations. This was accomplished through proximity interlocks directly to the transmission instead of the air brake system which increases safety for the driver and requires less maintenance and greatly reduces potential for failure. Our Glow Dial technology launched last year on the Accu-Max float gauge line greatly increases gauge visibility while reducing glare for the drivers. We look forward to the challenges that lie ahead in meeting the changing needs of our industry for decades to come.

To facilitate this goal we have just completed our most aggressive project to date by building the industry’s first LPG flow test laboratory. Located at our headquarters facility in Marshall, this laboratory employs state of the art technology to allow our engineering group to conduct flow and product validation testing on-site utilizing liquid propane, offering the opportunity to validate products in real application scenarios under our direct control. We are proud to reinvest in our industry with the construction of the first test facility of its kind in the world as a continuation of our commitment to providing the industry with the best equipment designs possible.

Over the course of time Marshall Excelsior Company has become a name that our customers can rely on not only for high quality products and service, but as a partner in building their business.  It is through this personal touch that our family owned and operated business has become the organization that it is today and we look forward to becoming your partner for the future!
