Structural Feature Forged ball valve adopts one-piece integral hot forging forming process, no casting porosity, sand hole and internal crack defects. The dense forging microstructure provides ultra-high mechanical strength, pressure resistance and temperature stability. Adopts floating ball or trunnion ball structure optional, with precision lapped ball core and sealing pair to achieve zero-leakage shutoff. Integral forging body features uniform wall thickness, strong pressure-bearing capacity and excellent anti-fatigue performance, suitable for ultra-high pressure and high-temperature industrial pipelines. Multiple connection methods and full/reduced bore designs meet diversified high-standard pipeline layout requirements, with compact structure and long service life.
Suitable Media High-temperature superheated steam, high-pressure oil gas, natural gas, liquefied gas, chemical corrosive media, high-purity process fluid and cryogenic liquefied medium. Widely applied in petrochemical high-pressure process units, power plant main steam pipelines, boiler auxiliary systems, offshore platforms, high-pressure energy transmission pipelines and severe-service industrial projects.

 

Features

1.Integral Forging High-Strength Structure

Different from cast steel valves, forged ball valve body is integrally forged by high-temperature hot forging process. The internal metal structure is dense and uniform, without casting defects such as pores, shrinkage cavities and inclusions. It has far higher tensile strength, pressure resistance and impact toughness, effectively resisting ultra-high pressure, thermal shock and mechanical fatigue. The overall structural stability is excellent, avoiding body cracking and leakage failure under extreme working conditions, which is irreplaceable for high-pressure industrial systems.

2.Ultra-High Pressure & Wide Temperature Adaptability

Professional forging material configuration covers full extreme working conditions: A105 carbon steel for conventional high-temperature and high-pressure service; F11/F22 alloy steel for 550℃ ultra-high temperature steam; LC3 forged steel for -196℃ cryogenic liquefied gas; F304/F316 stainless steel for corrosive media. It stably operates under Class2500 ultra-high pressure and extreme temperature difference, fully meeting severe service standards of thermal power, petrochemical and energy industries.

3.Precision Zero-Leakage Sealing Performance

The ball core and valve seat are processed by high-precision CNC machining and mirror lapping technology, with extremely low surface roughness. Soft seal configuration achieves bubble-tight zero leakage for clean media; upgraded Stellite hardfaced metal sealing pair resists high temperature, high pressure and particle scouring, maintaining stable sealing performance under long-term fluctuating working conditions. Floating and trunnion dual structures optional, adapting to different pressure and diameter requirements.

4.Fire-Safe & Explosion-Proof Safety Design

Complies with API 607 international fire-safe standard, equipped with graphite emergency auxiliary sealing structure. When soft seal fails under fire high temperature, it can still maintain effective shutoff to prevent medium leakage and fire diffusion. Built-in anti-static device derives static friction electricity, eliminating explosion risks of flammable and explosive media such as natural gas and liquefied gas. Blow-out proof stem structure ensures no stem ejection under extreme pressure, guaranteeing pipeline overall safety.

5.Compact Structure & Long Service Life

Integral forging integrated forming simplifies internal structure, with small overall volume and compact installation space. Dense metal structure effectively resists medium erosion and chemical corrosion, reducing wear and aging speed. The anti-fatigue forging body supports millions of stable switching cycles, realizing long-term maintenance-free operation, greatly reducing later operation and maintenance costs of high-pressure pipeline systems.

Typical Application Equipment

 

- Petrochemical ultra-high pressure process pipelines and reaction unit systems

- Thermal power plant main steam, boiler auxiliary and high-pressure water supply pipelines

- Offshore platform, marine high-pressure piping and energy transmission systems

- Cryogenic liquefied gas storage, transportation and low-temperature process projects

- High-pressure chemical, refining and flammable explosive medium pipeline systems

- Industrial high-standard severe service piping requiring high strength and zero leakage

 

Working Principle & Application Notes

 

Forged ball valve realizes pipeline opening, closing and flow regulation through 90°rotation of precision ball core. Full-bore design provides straight-through low-resistance flow channel for smooth medium circulation; closed ball surface completely blocks the flow channel to achieve tight shutoff. Floating ball structure is applicable for small-diameter medium-high pressure pipelines; trunnion ball structure is recommended for large-diameter and ultra-high pressure working conditions.Forged ball valve is specially used for high-pressure, high-temperature and extreme working conditions, not recommended for conventional low-pressure general pipelines due to cost factors. Welded connection is preferred for ultra-high pressure pipelines to ensure pipeline integrity; threaded/flanged connection is suitable for convenient maintenance occasions. Confirm material grade, pressure class, connection type and sealing form before ordering.
