Our forged steel flanged check valves provide superior backflow prevention in critical piping systems. Engineered with heavy-duty forged construction (ASTM A105/A182) and flanged connections (ASME B16.5), these valves deliver exceptional durability and leak-tight performance in high-pressure oil & gas, petrochemical, and power generation applications.
✔ 100% Forged Steel Body – Superior strength vs. cast alternatives
✔ Swing or Lift Design – Optimal for horizontal/vertical installations
✔ Fire-Safe Option – API 6FA compliant versions available
✔ Low Maintenance – No external operator required
✔ Rapid Closure – Minimizes water hammer effects
