Introducing the High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. Painstakingly crafted to perfection, these valves ensure unmatched Zero-Leakage performance across a wide array of challenging high-temperature and high-pressure applications. Experience reliability like never before with our meticulously engineered solutions.
Exquisitely crafted with unparalleled precision, the ball and seat of these valves are fortified with state-of-the-art hard coatings of chrome carbide or tungsten carbide. This incredible reinforcement delivers extraordinary resistance to erosion and abrasion, thereby significantly enhancing durability and operational reliability.
Our SNT High Performance Soft Seated Ball Valves are equipped with a pioneering HVOF coating system. Every valve undergoes meticulous mate-lapping through proprietary techniques, ensuring impeccable 100% sealing. The innovative live loading feature is designed to guarantee zero emissions, keeping the ball in constant contact with the seat for superior wiping action against contaminants. This revolutionary self-cleaning functionality prevents interference and damage from particles, making these valves the ultimate choice for demanding slurry and abrasive service applications.
Our innovative special packing combination is expertly engineered to meet stringent emission requirements of 100 ppm, while simultaneously reducing stem friction by an impressive 20%.
Ingeniously designed with an anti-blow out feature, our valves prevent stem blowout and potential damage, ensuring long-lasting safety and reliability.
Featuring a seat ring with wave spring and dual-scraper technology, this structure efficiently cleans the ball surface, maintaining a robust seal and optimal performance.
Our dual-sealing design ensures superior leakage protection by preventing flow contact with the spring, thus maintaining an impeccable leakage class.
The soft seat offers outstanding stability and reliability in sealing performance, bringing unparalleled peace of mind to your operations.
Our cutting-edge design includes draining and sweeping features to avert valve jamming, ensuring uninterrupted cleaning and operation.
Meeting API 607 standards, our valves are equipped with advanced fire-proof and anti-static functionalities, providing unwavering safety and compliance.
SNT Ball Valves are meticulously engineered to comply with an impressive array of international standards, including ASME B16.34-2009, ASME B16.10-2000, and API 589-2009. This versatile series proudly serves a wide range of industries, making significant contributions to sectors such as petroleum, chemical industry, light industry, pharmaceuticals, paper-making, metallurgy, and power stations, providing reliable solutions for various fluid control needs.
Their Outstanding Features Include:
A streamlined design crafted for effortless disassembly, ensuring hassle-free operations.
Thoughtfully designed with ease of maintenance as a priority, our ball valves feature an innovative non-tight fit design that allows for quick and straightforward servicing. This reduces downtime during periodic maintenance, boosting operational efficiency.
Employing cutting-edge sealing technology for maximum security and performance.
The multi-layer sealing of the stem and body provides dual protection through an expertly engineered combination of O-ring and graphite or PTFE. This ensures exceptional sealing performance, meeting high expectations for durability and reliability.
This innovative design rigorously adheres to the stringent TA-Luft/Shell SPE 77/312 standards, underscoring our commitment to excellence.
Extended Service Life for Superior Cost-Efficiency
Our metal seated ball valves undergo sophisticated processing techniques such as spray welding, spraying, and fusion welding. This process guarantees a superior 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 deliver outstanding performance and cost-efficiency.
Modular Design for Enhanced Convenience
The modular inner sealing design offers easy interchangeability between soft and metal seats, ensuring flexibility and reliability tailored to diverse application requirements.
