Company Information

Marsh has been manufacturing a line of steam and boiler heating products since the 1800’s. Quality and functionality is characterized by our line of products. Starting in 2003, we have initiated design and technology enhancements throughout our line.

We are pleased to announce new product and upgrades throughout our line. New in 2006 is the ability to choose from either a diaphragm style or stainless steel bellows style thermostatic heating element in our complete line Steam Trap Products. We are also now producing our new line of bucket traps as well as a wire-less heating element (and insert) into Marsh’s popular R-100 radiator supply valves.

Located, west of Chicago, in Elburn IL, all engineering, design, manufacturing and testing is located in our Elburn manufacturing facility. We have a long term and dedicated approach towards keeping these functions based in the USA, to ensure all elements of product and quality are not compromised.

See our web-site for basic product information; including Air Vents, FT vents, F&T traps, Steam Traps, Bucket Traps and Radiator Valves. Contact us if you have any further requirements or request other information.

Development and product enhancement is on-going. Special sizing or engineering requests are available for all basic products. Please contact us anytime we may be of service.

Thank you,
The Marsh Staff
