History of Sullivan Process Controls

Our History began as Sullivan and Sons in 1986 and began selling surplus instrumentation and controls. The company expanded into instrumentation repair in 1988 and opened a new service repair facility in northwest Louisiana. Continued growth allowed further expansion with the construction of a new facility in 1990 as well as the addition of key employees with technical expertise and certifications in both instrumentation and control valve engineering. Customer service and sales divisions were also increased to support the growing customer base that reached nationwide.

In 1994, the company entered the control valve market by producing a superior product that was reliable and cost effective for increasingly tight budgets. Sullivan and Sons, Inc., was able to quickly make its name synonymous with quality in the industry and become a leader in the remanufactured control valve market. A new valve assembly and repair facility was built to accommodate the growth. There has been a steady increase in both the instrumentation and control valve divisions as new product lines and quality personnel have been added.

In addition to sales and production facilities at the headquarters in northwest Louisiana are 20,000 square feet of warehousing that allow the ability to stock a large inventory of products for quick lead times.In 2001, with sales territories expanding and reaching throughout North America, the export division was created and began marketing across the globe. Products and services are now provided to companies all over the world including over a dozen foreign countries. In recent years new products such as Sullivan and Sons brand control valves and process controls, as well as relief valves and regulators, have been included in product offerings.

Sullivan Process Controls, has built a foundation for growth and success by providing top-notch products, by recruiting skilled high-character employees, by showing attention to detail, and, most importantly, by making customer service the #1 priority.
