Overview

IMI PBM, historically known as Pittsburgh Brass Manufacturing, is an American manufacturer of valves and flow-control components for sanitary and industrial applications. The brand is now part of IMI plc, the London-listed British engineering group, and operates under the IMI PBM name. Its product catalogue is organized into two broad families: Sanitary Valves for hygienic processing and Industrial Valves for demanding process and energy applications. The Sanitary Valves line includes 2-way ball valves, 3-, 4- and 5-way multi-port valves, poppet-type check valves, clean steam ball valves and clean steam trap valves, diverter port valves, Fabflex manifold assemblies, fire-test-qualified valves, Igenix block-and-bleed pigging valves, Igenix pinch valves, radial diaphragm tank outlet valves, rising stem sampling valves, self-cleaning ball valves, spray ball valves, tank outlet valves and zero dead leg valves. These products serve hygienic industries such as food and beverage, pharmaceutical and biotech, personal care, paint and resin, and pulp and paper. The Industrial Valves line covers 2-way ball valves, 3-, 4- and 5-way multi-port valves, ANSI flanged valves, cryogenic valves, diverter port valves, double block and bleed valves, Fabflex manifold assemblies, fire-test-qualified valves, instrument isolation valves, pigging valves, PSV switching valves, tank bottom valves, transmitter isolation valves and trunnion-mounted flanged valves. These are aimed at chemical and petrochemical, cryogenic, data center, energy, marine and offshore, and steel applications. Beyond valves, IMI PBM also offers marine automation and accessories, including automation and controls, emission reduction valves, extended locking lever handles, flush and bleed rings, locking handles, positioners, solenoids and V-balls for control. The company also presents affiliated IMI products such as IMI Fluid Kinetics vent silencers (BOS, EVO, Next Generation Silencer and Stack Silencer) and IMI Thompson Valves' IMI Maxseal. IMI PBM supports customers with a resource library that includes a tool kit, literature, a build-a-part-number tool, certifications, installation, operation and maintenance documentation, product bulletins, technical details, videos and animations, and FAQs. The company operates a documentation portal and order tracking for customers and representatives, and maintains a network of regional managers and affiliated companies. Its headquarters and primary contact line are in the Irwin, Pennsylvania area, reflecting its Pittsburgh-area industrial roots.

History

IMI PBM traces its identity to Pittsburgh Brass Manufacturing, an American valve maker rooted in the Pittsburgh, Pennsylvania industrial region. Over time the business became known simply as PBM and built a reputation for ball valves and related flow-control products used in sanitary and industrial process lines. The company was acquired by IMI plc, the London-listed British engineering group, and was integrated into IMI's fluid-control portfolio under the IMI PBM name. This placed PBM alongside other IMI valve and flow-control businesses, and the brand's website now presents affiliated IMI products such as IMI Fluid Kinetics vent silencers and IMI Thompson Valves' IMI Maxseal alongside its own catalogue. Under IMI ownership, IMI PBM has developed two clearly defined product families. The Sanitary Valves range addresses hygienic processing needs with 2-way ball valves, 3-, 4- and 5-way multi-port valves, poppet-type check valves, clean steam ball valves and clean steam trap valves, diverter port valves, Fabflex manifold assemblies, fire-test-qualified valves, Igenix block-and-bleed pigging valves, Igenix pinch valves, radial diaphragm tank outlet valves, rising stem sampling valves, self-cleaning ball valves, spray ball valves, tank outlet valves and zero dead leg valves. These products are marketed to food and beverage, pharmaceutical and biotech, personal care, paint and resin, and pulp and paper customers. The Industrial Valves range serves heavier process duties with 2-way ball valves, 3-, 4- and 5-way multi-port valves, ANSI flanged valves, cryogenic valves, diverter port valves, double block and bleed valves, Fabflex manifold assemblies, fire-test-qualified valves, instrument isolation valves, pigging valves, PSV switching valves, tank bottom valves, transmitter isolation valves and trunnion-mounted flanged valves. Target industries include chemical and petrochemical, cryogenic, data centers, energy, marine and offshore, and steel. IMI PBM also supplies marine automation and accessories, including automation and controls, emission reduction valves, extended locking lever handles, flush and bleed rings, locking handles, positioners, solenoids and V-balls for control. The company maintains a resource library with a tool kit, literature, a build-a-part-number tool, certifications, installation, operation and maintenance documentation, product bulletins, technical details, videos and animations, and FAQs. It operates a documentation portal and order tracking for customers and representatives, and maintains a network of regional managers and affiliated companies. Its contact line and operations are associated with the Irwin, Pennsylvania area, reflecting its Pittsburgh-area heritage.
