Forged Steel Butt Welded Check Valve

Forged steel butt welded check valves are designed to prevent backflow in high-pressure piping systems, ensuring unidirectional flow and protecting equipment from damage. Constructed from high-grade forged steel (ASTM A105, A182 F304/F316, etc.), these valves offer exceptional strength, durability, and resistance to extreme temperatures and corrosive environments.

Forged steel butt welded check valves are designed to prevent backflow in high-pressure piping systems, ensuring unidirectional flow and protecting equipment from damage. Constructed from high-grade forged steel (ASTM A105, A182 F304/F316, etc.), these valves offer exceptional strength, durability, and resistance to extreme temperatures and corrosive environments.

The butt weld ends provide a leak-proof, permanent connection, making them ideal for critical applications in oil & gas, power plants, and chemical processing.

✔ Swing or Lift Design – Depending on flow requirements

✔ High-Pressure Resistance – Suitable for Class 150 to 2500 (ASME B16.34)

✔ Zero Leakage – Tight sealing to prevent reverse flow

✔ Forged Steel Body – Superior strength compared to cast valves

✔ Butt Weld Connection – Ensures a robust, permanent joint

✔ Fire-Safe Option – Available for hazardous environments (API 607 compliant)
