Spence Engineering Company is the industry's leader in the steam equipment regulation field and is an ISO 9001 certified custom manufacturer of steam specialty & fluid control devices. Our sales offices are located throughout the United States, Europe, Asia, Central and South America, and the Middle East.

Since it's founding in 1926, Spence Engineering Company has engineered for reliability and longevity. It was the lack luster performance and the frequency of maintenance calls for pressure reducing valves of the 1920s that inspired Paulsen Spence to design the Spence Type ED in 10925.

Since it's earliest days Spence has continued it's "History of Innovation" with new product development and improvements to Spence's "quality first" manufacturing philosophy. This has enabled Spence to develop and manufacture quality steam specialty and fluid control products that meet the changing needs of today's HVAC and Industrial marketplaces, just as Paulsen Spence did in the early 1900s.
