Weir Valves Valve Alternative
Weir Valves & Controls / Trillium Flow Technologies
Weir Group's Valves & Controls division (now operating as Trillium Flow Technologies after a 2019 divestiture) is one of the most recognised names in high-integrity forged steel valves for power generation, nuclear, oil & gas, and petrochemical industries. The legacy Weir brands — Atwood & Morrill, Pacific Valves, Hopkinsons, and BDK — each have a long history in critical service markets. In India, Weir/Trillium products are specified for thermal power plant feedwater systems, HRSG steam circuits, and high-pressure refinery service. Vajra supplies equivalent forged and cast steel gate, globe, and check valves for comparable service at significantly lower cost with full IBR and TPI documentation.
