What Is A Forged Ball Valve?

Forged ball valve use forging processes to manufacture their core components, including valve body and bonnet. It uses a spinning ball to open or close pipes or control flow.
The valve's core feature is the forging process, which differs from the casting ball valves in strength, sealing and corrosion resistance. Widely used in high pressure, high temperature or safety critical industrial environment.
I. Core Definition and Operating Principle
The core of forging ball valve is forging valve body and rotating ball. How it works is simple:
The valve consists of a sphere with a hole in the inside and the sphere is rotated by valve stem.
When the opening of the ball is aligned with the axis of the pipe, the valve is fully opened to allow a smooth flow of media,such as liquid or gas.
When the ball rotates 90 degrees, the hole is perpendicular to the axis of the pipe and the valve closes completely, blocking the flow of media.
The flow can also be adjusted by rotating the ball at different angles (0-90°). ii. Main features (compared to Cast Ball Valves)
The forging process gives it a unique advantage. The following table provides a clear comparison of the core differences between the two:
Comparison of Casting Size of Forged Ball Valve
Manufacturing process: Metal billet is forged and formed with dense internal structure. Molten metal is cast and may contain pores and pinholes.
Mechanical strength: high strength, toughness, impact and pressure resistance. Low strength, poor toughness, high leakage risk under high pressure.
Applicable Applications: High pressure (such as oil and gas production, high pressure pipelines, etc.), high temperature, high purity media environment. Low pressure, ambienttemperature environment (such as civil water supply and drainage, low pressure chemical pipeline, etc.).
Cost: High manufacturing costs, generally expensive. It's cheaper to make and more affordable.
III. Commonly used applications
Forged ball valves are mainly used in industries with stringent safety and reliability requirements due to their superior performance:
Oil and gas industry: Oil and gas production and transportation pipelines affected by high pressure and corrosive media.
Chemical industry: piping control of high temperature and high pressure reactors to prevent media leaks and accidents. Energy industry: steam pipes designed for thermal and nuclear power plants to withstand high temperatures and pressures.
High-end equipment: Hydraulic or fluid control systems for ships, aerospace, etc.
