Forged steel ball valves are made from high-quality carbon steel, alloy steel, or stainless steel processed using forging techniques (such as free forging and die forging) as the main material for the valve body. They achieve the shut-off or connection of pipeline media through the rotation of the ball. Their core advantage lies in the forging process, which endows the valve body with high density, high strength, and excellent mechanical properties.
They are free from casting defects (such as porosity and sand holes), can withstand high pressure, impact, and frequent operation, and are suitable for applications such as petroleum and chemical industries with stringent requirements for valve body strength.
Compared to cast steel ball valves, they have higher pressure resistance and a more compact structure, but large-diameter versions are more difficult to manufacture and slightly more expensive. They must comply with industry standards such as GB/T 12237 and API 6D to ensure sealing reliability and service life under high-pressure conditions.
