THREE-PIECE TRUNNION-MOUNTED BALL VALVES
In high-stakes oil and gas operations, dependable, leak-tight isolation is non-negotiable. Engineered by Multi-Leak Barrier (MLB), these three-piece trunnion-mounted ball valves are designed to perform under extreme pressure in large-scale applications. Featuring a robust trunnion-supported stem, line pressure is efficiently absorbed to reduce seat friction, delivering consistently low operating torque even at maximum working pressure.
As an authorized supplier of the full MLB trunnion ball valve lineup, we provide solutions engineered to the highest industry benchmarks. Every valve in this series includes an integrated emergency sealant injection system to establish a secondary backup seal should primary surfaces encounter wear or damage. Built with certified, high-grade materials, MLB valves resist sulfide stress cracking and severe corrosive elements—ensuring reliability across varying temperatures, line pressures, and sour gas environments.
Designed for fast, straightforward field maintenance, this MLB series supports tailored configurations including extended stems, locking devices, transition piping, and direct-mount actuation.
