Valbart was founded in 2003 as a joint venture. Since then, the company has witnessed tremendous growth and has been recognized as the fastest-growing firm in its sector. Acquired in 2010 by Flowserve Corporation following a long period of sustained excellence, the brand further expanded its technical resources and product offerings. Today, Valbart’s range of standard and fully engineered products covers most valve requirements for oil and gas applications.

Valbart specializes in engineered solutions, including: high-temperature, metal-seated valves; high-pressure valves; cryogenic service products; and high-cycle valves. The brand is widely known for its API 6A and API 6D trunnion-mounted ball valves (TMBVs) and is also recognized for its production of trunnion-mounted control ball valves (TMCBVs), cryogenic valves, valves for subsea service, twin ball double block and bleed valves, and rising stem, friction-free ball valves.

The brand’s production equipment leverages the latest automation technology and is specially engineered to meet the requirements of advanced large valve manufacturing.
