March 8, 2021

  • Share on:

(Birmingham, Alabama) McWane Plant & Industrial (MPI) has acquired the Tri-Seal Valve product line, including the widely-specified Quarter-Flex family of high-performance industrial butterfly valves.

For decades, Tri-Seal has been among the leading domestic manufacturers of industrial butterfly valves.  The products are 100% American-made, including domestic castings and components.  They meet all project requirements for domestic products including Buy American, American Iron and Steel, and the American Recovery and Reinvestment Act.

First introduced in the 1960s, Tri-Seal valves are renowned for use in extreme applications including chemical manufacturing, marine, mining, oil/gas, power generation, and other specialized industrial environments.

The Tri-Seal line expands McWane Plant & Industrial’s product offering for industrial fluid control applications, complementing the company’s Kennedy Valve, Waterman and Clearwater Manufacturing offerings.
