Introducing the High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. Expertly crafted and diligently engineered, these state-of-the-art valves are designed to provide unparalleled Zero-Leakage performance across a diverse range of high-temperature and high-pressure service applications.
Exquisitely crafted with unparalleled precision, the ball and seat of these exceptional valves are fortified with cutting-edge hard coatings of either chrome carbide or tungsten carbide. This outstanding fortification offers remarkable resistance against both erosion and abrasion, significantly boosting the longevity and reliability of each valve.
Our SNT High Performance Soft Seated Ball Valves are equipped with an advanced HVOF coating system. Each valve is meticulously mate-lapped using our proprietary techniques to ensure a perfect 100% sealing. The innovative live loading feature guarantees zero emissions, while maintaining constant contact between the ball and seat, effectively wiping away contaminants. This revolutionary self-cleaning mechanism prevents any interference or damage from particles, making these valves the ideal choice for slurry and abrasive service applications.
The specially engineered packing combination is designed to meet the stringent emission requirement of 100 ppm, while ingeniously reducing friction by 20% to the stem, enhancing efficiency and longevity.
The robust anti-blowout design is a safeguard against stem ejection, effectively preventing potential damage and ensuring reliable operation in varied conditions.
The innovative seat ring structure, featuring a wave spring and dual-scraper, ensures a pristine ball surface and maintains superior sealing integrity.
Our cutting-edge dual-sealing technology guarantees impeccable leakage class by ensuring the flow does not come into contact with the spring, providing consistent and secure performance.
The soft seat sealing performance stands out for its exceptional stability and reliability, offering peace of mind in every application.
The sophisticated design for draining and sweeping prevents valve jamming, maintaining optimal cleanliness and functionality.
Fully compliant with API 607 standards, these valves offer remarkable fire-proof and anti-static capabilities, ensuring safety and reliability in demanding environments.
SNT Ball Valves are meticulously engineered to comply with a multitude of international standards, including ASME B16.34-2009, ASME B16.10-2000, and API 589-2009. These versatile and robust valves find extensive applications across a wide spectrum of industries, such as petroleum, chemical industry, light industry, pharmaceuticals, paper-making, metallurgy, and power stations, showcasing their adaptability and exceptional performance in diverse operational contexts.
Their Outstanding Features Include:
Innovatively streamlined design ensures effortless, hassle-free disassembly.
Crafted with a focus on user-centric maintenance, our ball valves boast a non-tight fit design that facilitates rapid servicing. This design innovation minimizes downtime during periodic maintenance, enhancing operational efficiency and productivity.
Cutting-edge sealing technology for unmatched security and reliability.
The multi-layer sealing system of stem and body offers unparalleled dual protection through an ingenious combination of O-ring and graphite or PTFE. This ensures exceptional sealing performance, safeguarding against leaks and enhancing durability.
This groundbreaking design rigorously meets the stringent TA-Luft/Shell SPE 77/312 standards, reinforcing its superior quality and compliance.
Extended Service Life for Superior Cost-Efficiency
Our metal seated ball valves undergo state-of-the-art processing techniques such as spray welding, spraying, and fusion welding. This sophisticated process ensures a hardness range of HRC58-73 and a robust binding force of 80-40MPa. With an impressive on-off cycle lifespan exceeding 100,000 operations and a leakage class of ANSI VI, these valves promise reliability and efficiency, providing remarkable cost-efficiency over time.
Modular Design for Enhanced Convenience
The modular inner sealing design enables effortless interchangeability between soft and metal seats, guaranteeing flexibility, reliability, and tailored performance for varying applications and operational needs.
Varied Connection Types for User Convenience
Our valves feature a variety of connection types, including flanged (RF, FF, FM, G, RJ), screw-thread, and BW, all of which conform to international standards. This ensures seamless integration and user-friendly operation, providing unparalleled convenience and flexibility for diverse applications.
