In industrial fluid systems, high temperature, high pressure, abrasive particle-laden media and hydrogen sulfide corrosive fluids represent the biggest challenge for valve equipment.Standard soft-seated valves are prone to wear, cannot withstand high temperatures, and cause frequent leakage and unplanned shutdowns, significantly raising plant operation and maintenance costs.
VATTEN newly launches its upgraded series of metal seated ball valves. Custom-engineered for the harshest industrial working conditions, the product delivers outstanding safety, durability and broad working condition adaptability. Let us take an in-depth look at this hardcore industrial equipment!
Ⅰ. Engineered for Extreme Severe Working Conditions
VATTEN metal seated ball valves adopt high-precision metal-to-metal sealing structure to overcome the drawbacks of soft-seated valves, compatible with a full range of complex media:

Ⅱ. Eight Core Advantages to Safeguard Industrial Operation
01 Ultra-Wear Resistant Self-Cleaning Seats to Extend Service Life
For unclean process media, the self-cleaning seat system removes particulate contaminants, minimizes leakage and prolongs service life. It drastically reduces leakage risks and ensures stable operation under pulp, ore slurry and catalyst powder service conditions.
02 Comprehensive Safety Certifications, Standard Specification for Petrochemical Industry

- Anti-Static Construction: Built-in spring dissipates static electricity to eliminate ignition risks when conveying flammable media.
- Blowout-Proof Stem: Prevents stem ejection even if packing fails, avoiding catastrophic safety accidents.
03 DBB Double Block & Bleed Design
When the valve closes, sealing surfaces on both sides achieve simultaneous sealing. The body cavity enables independent pressure relief and venting, ensuring safer isolation and maintenance work and meeting stringent isolation requirements for oil, gas and chemical industries.

08 Custom Cryogenic Version
Extended cryogenic bonnet design reliably withstands cryogenic service down to -196°C (liquid nitrogen). Specially developed for LNG and low-temperature chemical pipelines.
Ⅲ. Wide Coverage of Industrial Application Scenarios
Oil & Gas: Sour oil & gas production, long-distance transmission pipelines, working conditions with high temperature, high pressure and hydrogen sulfide corrosion
Petrochemical & Chemical Industry: High-temperature reactors, slurry transportation, shut-off and isolation of corrosive solutions
Power & Heating: High-temperature steam, thermal oil and boiler circulation systems
Mining & Metallurgy: Ore slurry, powder materials and media carrying highly abrasive solid particles

Ⅳ. Complete Specification Portfolio for One-Stop Selection
Supported by a comprehensive specification system, our valves enable convenient one-stop selection:
Two-piece ball valves conforming to GB PN standards cover PN16, PN25, PN40, PN63 and PN100. We also supply ASME flanged ball valves of Class150 and Class300 to satisfy standards for domestic and overseas projects.
Standardized design is adopted for face-to-face dimensions, flange dimensions and ISO 5211 mounting flanges for actuators. Stem heights are categorized for ambient, high and cryogenic temperature service, accelerating model selection and avoiding dimension mismatches.
Valve bodies and balls are machined from forged steel with micron-level machining precision. Excellent fitting accuracy of sealing surfaces supports customized requirements for vacuum service and zero-leakage class.
Ⅴ. Why Choose VATTEN Metal Seated Ball Valves?
Faced with extreme industrial conditions including high temperature and high pressure, abrasive slurry media, hydrogen sulfide corrosion, and ultra-low-temperature LNG service, conventional soft-seated valves are prone to internal leakage caused by wear, frequent shutdowns and replacements, which greatly increase project operation and maintenance costs. Adhering to German precision manufacturing standards, VATTEN metal seated ball valves deliver long-term and reliable fluid control solutions for industrial systems in four core dimensions: superior craftsmanship, comprehensive safety, complete specifications and reliable after-sales service, serving as the optimal shut-off valve for harsh working conditions.
01 Self-Developed Premium Craftsmanship, Doubled Wear Resistance and Service Life
We independently master core manufacturing technologies including precision forging, ultra-precision spherical grinding and supersonic spraying of hard alloys. All valve bodies and balls are manufactured from forged steel, fundamentally eliminating inherent defects of castings such as porosity and looseness. The sealing surface can be customized with wear and corrosion-resistant coatings such as tungsten carbide, Stellite and nickel-based alloys. Combined with micron-level precision grinding technology, the ball and seat sealing pair achieves extremely high fitting accuracy.
Equipped with self-cleaning spring pre-tightened seats, the valve can automatically flush away dust, fibers and scaling impurities in the medium during operation. It maintains jamming-free performance and zero internal leakage during long-term switching, with a far longer wear-resistant service life than ordinary domestic metal seated ball valves.
02 Full Certification Support, Stable Protection for High-Risk Working Conditions
The full product range has obtained multiple authoritative certifications including API 607 / API 6FA fire safety certification and ISO 15848 low emission certification. Standard configurations include anti-static structure, anti-blowout stem and DBB double block & bleed structure, ensuring safe operation for flammable, explosive and hydrogen sulfide-containing pipelines in oil & gas, chemical and coal chemical industries.
The valves feature wide temperature and pressure adaptability: the applicable temperature ranges from -196°C cryogenic liquid nitrogen condition to 425°C conventional high temperature, with customized models resistant to a maximum temperature of 815°C. The pressure rating covers PN10~PN250 and Class150~Class1500, fully adapting to all kinds of extreme high/low temperature and high-pressure scenarios.
03 Standardized Complete Specifications, One-Stop Model Selection
Supported by a complete product specification matrix, our valves are compliant with both domestic and international project standards, covering full GB PN series and ASME Class series. All structural lengths, flange dimensions and ISO 5211 actuator mounting flanges adopt standardized design. Bonnet heights are classified for ambient, high and cryogenic temperature scenarios to ensure error-free model matching.
Multiple actuation modes are available, including manual lever, gearbox, pneumatic and electric actuators. Custom solutions such as vacuum service adaptation, zero-leakage grade and special materials (Hastelloy, Titanium) are supported, widely applicable to pipeline systems in power, oil & gas, mining, papermaking and fine chemical industries.
04 Full-Lifecycle Quality Control, Low Operation Cost and High Cost Performance
We have established a closed-loop full-process quality inspection system. Every valve undergoes strict full-range testing, including spectral re-inspection of raw materials, on-site process patrol inspection, valve body hydrostatic and air tightness tests, and high/low temperature fatigue tests. Full production traceability is realized for every product, effectively reducing unplanned factory shutdowns and cutting comprehensive losses caused by parts replacement, manual maintenance and production suspension.
Compared with imported equivalent valves, VATTEN products feature shorter delivery cycles and faster local after-sales response while maintaining equivalent premium quality. Integrating German precision manufacturing and localized high cost performance, we provide enterprises with sustainable and low-cost long-term fluid control solutions.
