PBM - ADJUST-O-SEAL®
Fabflex valve assembly

PBM presentation
PBM (Pittsburgh Brass Manufacturing) is a company over 100 years old that began as a non-ferrous foundry in 1899 along the Monongahela River in Pittsburgh. 
Outgrowing this location, the foundry was moved in 1918 to the heart of the industrial section along the Allegheny River. The first floor of a five-story building housed the foundry. The upper floors were developed into a machine shop that manufactured blast furnace and steel plant fittings. 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 a leading producer of dependable, high quality valves.

PBM fabflex Adjust-O-Seal® ball valve assembly
"space saving configurations"
​Space-saving pipe and valve configurations designed to accommodate special industrial and sanitary applications.

• can be shipped in lengths up to 18’, with multiple manual and automated valves pre-installed.
• 100% testing before shipment ensures proper performance.
• Minimal dead space reduces areas where media could become trapped.
• Blank valve pads can be provided to accommodate future process expansion.
• Valve mounts flush with the inside vessel wall, minimizing dead space.
• True-Bore means that the I.D. of the ball, seats and end fittings is identical to the I.D. of the tubing. There are no pockets or dead space in the through path, and no temperature fluctuations or pressure drops caused when media flows from tubing through a reduced port ball valve or a full-port ball valve. (True-Bore is standard to all Igenix® Two-Way and Igenix Multi-Port valves, and optional in other PBM valves.)
