What is a forged ball valve

Forged steel ball valves are ball valves manufactured using forging processes, inheriting the fundamental characteristics and advantages of ball valves while also achieving higher strength and superior corrosion resistance through forging. Below is a detailed introduction to forged steel ball valves.

I. Definition and Classification

‌Definition:‌ Forged steel ball valves are valves produced by processing metal materials into spherical valve bodies and other critical components through forging techniques, followed by assembly and testing.

‌Classification:‌

• ‌By Pressure Rating:‌ Low-pressure forged steel ball valves and high-pressure forged steel ball valves.
• ‌By Material:‌ Stainless steel forged ball valves, carbon steel forged ball valves, etc.
• ‌By Structure:‌ Two-piece, three-piece, etc.

II. Working Principle

The operation of a forged steel ball valve relies on rotating the valve stem to open or close the valve. When the stem is rotated 90 degrees, the passage in the ball aligns with or deviates from the passage in the valve body, enabling the valve to open or close.

III. Features and Advantages

• ‌High Strength:‌ The forging process enhances the strength and hardness of the valve body and other critical components, allowing them to withstand higher pressures and temperatures.
• ‌Excellent Sealing:‌ The sealing surfaces between the ball and valve seats typically use metal or soft sealing materials, ensuring reliable sealing performance.
• ‌Corrosion Resistance:‌ Forged steel ball valves made of corrosion-resistant materials (e.g., stainless steel) can endure harsh environments for extended periods without corrosion.
• ‌Easy Operation:‌ Forged steel ball valves are available in manual, pneumatic, or electric operation modes, making them simple to operate and maintain.

IV. Applications

Forged steel ball valves are widely used in industries such as oil, chemical, natural gas, and metallurgy, as well as in long-distance natural gas pipelines containing hydrogen sulfide, high levels of impurities, and severe corrosion. Due to their high strength and excellent sealing performance, forged steel ball valves play an irreplaceable role in these fields.
