Unit Process was founded in 1952 by a Dow chemical engineer named Ray Loesby. The original intent was that Unit Process would serve as a manufacturer's representative for the chemical and mineral industries. By 1954, Ray began focusing on fluid handling and process equipment, including valves, pumps, and instrumentation. Throughout the 1960s and 1970s, Unit Process continued to expand its product offering and regional presence. Electric heat tracing and other specialty products were introduced, while sales offices were established in Hawaii, Oregon, Eastern Washington and Alaska. The Loesby family managed the company through the years until Bray Controls purchased the company in 2000. Bray Controls was one of the product lines represented by Unit Process, with a focus on manufacturing butterfly, ball and check valves, actuators, and controls. At the time Bray purchased UPCO, Bray also owned several other independent representative/distributor companies. Bray has proven to be an excellent partner for Unit Process, providing a renewed investment in people and financial stability to what was already a well established business with a solid reputation. Unit Process Company has continued to flourish since the purchase, resulting in steady and consistent growth. Unit Process continues to maintain a strong presence in the Pacific Northwest. Today, Unit Process is over 65 years old and continuing to grow. The company employs 18 individuals, many of whom are degreed Engineers and is headquartered in Everett, Washington.
