PBM - ADJUST-O-SEAL®
​3-4-5 way multuíport ball valve

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 multiport Adjust-O-Seal® ball valve
"seals at every port"
​Whether the application is in a chemical plant, paper mill, food plant, manufacturing environment, or other industrial setting, PBM’s line of Industrial Valves can handle any type of rigorous and general purpose applications.
4- and 5-way Multi-Ports are true multi-port valves with seals at every port. This design makes the multi-port ideal for flow switching operations. In some applications, this valve can replace as many as four ordinary 2-way valves, with corresponding savings in piping and fittings.

• Unique Adjust-O-Seal® feature allows in-line valve adjustment to compensate for normal wear on valve seats. Note: valves DO NOT have o-rings.
• Choose from 4-way and 5-way flow patterns available offering for 90˚, 180˚ and 360˚ operation
• Full-port diameters minimize pressure drops (1/2 - 4”)
• Upstream and downstream bubble-tight sealing capability allows valve body cleaning, purging, and draining.
• Stem assembly accommodates PBM Direct Mount Actuation for accurate alignment and increased cycling life.
• In some processes, a single Multi-Port ball valve can replace several 2-way valves in a piping system, reducing costs and simplifying flow control with actuation.
• Full port design
• Valves are full vacuum
• Specifiy PBM flow pattern for 3, 4, or 5-way valves.
• Piggable “Y” Port valves are also available. Contact PBM
