Introducing the High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. These valves are meticulously engineered to provide stellar Zero-Leakage performance, even in the most demanding high-temperature and high-pressure service applications. Experience reliability and precision like never before with this cutting-edge valve series.
With unparalleled precision, the ball and seat of these valves are expertly crafted and reinforced with advanced hard coatings, such as chrome carbide or tungsten carbide. This exceptional fortification guarantees extraordinary resistance to erosion and abrasion, significantly enhancing the valves' longevity and reliability in challenging conditions.
Our SNT High Performance Soft Seated Ball Valves are equipped with a state-of-the-art HVOF coating system. Each valve is meticulously mate-lapped using proprietary techniques to ensure a flawless and impeccable 100% sealing. The innovative live loading feature guarantees zero emissions as the ball continuously maintains contact with the seat, effectively wiping away any contaminants. This advanced self-cleaning mechanism prevents interference and damage from particles, making these valves the ultimate choice for slurry and abrasive service applications.
Our specially engineered packing combination not only meets stringent emission requirements of 100 ppm but also innovatively reduces stem friction by 20%, ensuring smoother and more efficient operation.
Ingeniously designed with an anti-blowout feature, this valve expertly prevents stem ejection, thereby safeguarding against potential damage and ensuring long-lasting durability.
Equipped with a sophisticated wave spring seat ring and dual-scraper system, our valve effortlessly cleans the ball surface, ensuring pristine operations and maintaining impeccable sealing effectiveness.
The dual-sealing mechanism is meticulously crafted to uphold an impeccable leakage class by preventing flow contact with the spring, ensuring superior sealing integrity.
Our soft seat sealing performance is engineered for stability and reliability, offering consistent and unwavering performance under various conditions.
Designed with an advanced draining and sweeping system, our valve efficiently prevents jamming by maintaining cleanliness, ensuring seamless and reliable function.
Conforming to API 607 standards, our valve is robustly equipped with fire-proof and anti-static features, offering unparalleled safety and reliability in demanding environments.
At SNT Machinery (Qingdao) Co., Ltd., our High Strength Metal Seated Trunnion Ball Valves for Oil and Gas are meticulously crafted to adhere to a comprehensive range of esteemed international standards, including ASME B16.34-2009, ASME B16.10-2000, and API 589-2009. This extensive series is the preferred choice for a multitude of industrial applications spanning petroleum, the chemical sector, light industries, pharmaceuticals, paper production, metallurgy, and power generation facilities.
Their Remarkable Features Include:
Aerodynamic design for seamless and hassle-free disassembly.
Engineered with an emphasis on maintenance efficiency, our ball valves boast a non-tight fit design, which significantly simplifies servicing. This design drastically reduces downtime during routine maintenance, ensuring continued operational efficiency.
State-of-the-art sealing technology ensuring ultimate security and performance.
The multi-layer sealing system of both stem and body provides dual-layer protection by combining an O-ring with graphite or PTFE. This configuration guarantees superior sealing efficiency and reliability.
This revolutionary design is fully compliant with the stringent TA-Luft/Shell SPE 77/312 standards, promising top-tier environmental safety.
Prolonged Service Life for Exceptional Cost-Effectiveness
Our metal seated ball valves undergo cutting-edge processing techniques, including spray welding, spraying, and fusion welding. This meticulous approach secures a hardness range of HRC58-73, a binding force of 80-40MPa, and a remarkable operational lifespan exceeding 100,000 open-close cycles, all while maintaining a leakage class of ANSI VI.
Modular Design for Superior Convenience
The modular internal sealing design offers effortless interchangeability between soft and metal seats, providing unmatched flexibility and dependability.
