The function of Forged Ball Valve

Q: What is the main function of a Forged Ball Valve?

A: The forged ball valve is a high‑strength ball valve with forged steel body. It is mainly used to fully open or fully shut off the pipeline medium. It can also realize throttling under specific working conditions. The forged body delivers superior structural strength, suitable for high‑pressure, high‑temperature and harsh industrial working conditions. It can reliably cut off corrosive, high‑temperature and high‑pressure fluids in oil, chemical, power and petrochemical industries. The valve adopts forged blank processing, with compact and solid body structure, to resist high pressure impact and thermal stress.

Conclusion: Therefore, the main function of Forged Ball Valve is reliable on‑off control for high‑pressure and high‑temperature pipelines, providing strong structural performance for harsh industrial fluid systems.

The principle of using Forged Ball Valve

Q: What is the working principle of a Forged Ball Valve?

A: The forged ball valve operates by 90° rotation of the internal ball core. The forged valve body is processed from solid forged steel block, which is different from cast valve body. The ball core with through‑hole rotates with the actuator or manual handle. When the hole is aligned with the two ports, the valve is fully open; when the ball rotates 90°, the passage is blocked and the valve is fully closed. The seat assembly provides tight sealing. It can be designed as floating ball or trunnion‑mounted ball structure. Forged body has better density, less casting defects, and can withstand higher pressure and temperature fluctuation. It supports manual, gear, electric and pneumatic actuation modes.

Conclusion: Therefore, the working principle of Forged Ball Valve relies on 90° rotation of ball core for on‑off control. Its solid forged body ensures stable performance under high‑pressure and high‑temperature working conditions.

The operating conditions and advantages of Forged Ball Valve

Q: What are typical applications and key advantages of Forged Ball Valves?

A: Forged ball valves are widely used in petrochemical, oil & gas, power plant, chemical process and high‑pressure pipeline systems. Common pressure classes: Class 150‑Class 2500; size range: DN15‑DN100; working temperature: -29℃ ~ 425℃. Main advantages:

High‑strength Forged Body: Solid forged steel material, high density, no casting porosity, good resistance to high pressure and thermal shock.

Excellent Sealing Performance: Floating ball or trunnion‑mounted structure, soft‑seat or metal‑seat sealing for different medium requirements.

Good Reliability: Low leakage rate, long service life under harsh working conditions.

Flexible Actuation: Compatible with manual, gear, electric, pneumatic actuators for manual or automatic operation.

Wide Material Selection: A105, F304, F316L, F51 duplex stainless steel and other forged materials for various corrosive and high‑temperature media. Compact Structure: Small overall dimension, easy for installation in limited space.

Conclusion: Therefore, Forged Ball Valve is the preferred choice for high‑pressure and high‑temperature industrial pipelines. Its forged solid body brings outstanding mechanical strength and stable sealing performance for harsh process conditions.
