Forged steel valve

What is a Forged Steel Valve?

A forged steel valve is a valve whose body is manufactured by forging process. Compared with cast steel valves, forged steel valves have denser metal structure, higher strength, and better toughness, making them especially suitable for high pressure, small diameter (usually DN50 and below), and critical service conditions.

Forged steel valves are widely used in instrument lines, sampling systems, high pressure small-diameter pipelines, nuclear power plants, and other occasions where reliability is paramount.

Forging vs Casting

Forging

  • Dense, fine grain structure
  • High strength
  • Good toughness
  • Small diameter (DN50↓)
  • Higher cost

Casting

  • Possible porosity, slag inclusion
  • Medium strength
  • General toughness
  • All sizes available
  • Lower cost
