Pittsburgh Brass Manufacturing earned a reputation as a reliable supplier to the steel industry. In the late 1950s, James H. Brennan Sr. shifted the company’s operations to the development of specialty Ball Valves. The first Ball Valve was shipped in 1960.

In 1968, for the purpose of consolidating operations and allowing for future expansion, PBM moved to its present site in Irwin, 20 miles southeast of Pittsburgh, PA. From this location, the first Flush Bottom Mounted Ball Valve and True Multi-Port Ball Valves were developed and manufactured. Today we are one of the leading producers of sanitary and industrial valves.

In 2019, PBM, Inc. was acquired by IMI Critical Engineering. We are now re-branded as IMI PBM and we look forward to growing as a company and enhancing our customer’s experience by providing safe, reliable, high quality valves.
