Introducing the High Performance Soft Seated Ball Valve series, a masterpiece by SNT Machinery (Qingdao) Co., Ltd. These valves are meticulously engineered to deliver an unparalleled Zero-Leakage performance, making them the ideal choice for a range of high-temperature and high-pressure service applications. Experience the precision and reliability that define our cutting-edge solutions.
Crafted with extraordinary precision, each valve's ball and seat are fortified with state-of-the-art hard coatings such as chrome carbide or tungsten carbide. This exceptional reinforcement guarantees remarkable resistance to erosion and abrasion, significantly enhancing the longevity and reliability of our valves. Trust in our commitment to quality for your most demanding applications.
Our SNT High Performance Soft Seated Ball Valves are equipped with a state-of-the-art HVOF coating system, ensuring unrivaled durability. Each valve undergoes meticulous mate-lapping using exclusive proprietary techniques, guaranteeing a flawless 100% sealing. The innovative live loading feature ensures zero emissions and constant contact between the ball and the seat, effectively wiping away contaminants. This advanced self-cleaning mechanism prevents interference and damage from particles, making these valves the ultimate solution for demanding slurry and abrasive service applications.
The special packing combination is engineered to meet stringent emission requirements of 100 ppm, while ingeniously reducing stem friction by an impressive 20%.
Our anti-blowout design effectively safeguards against stem ejection, ensuring the prevention of damage with robust reliability.
The innovative seat ring structure, featuring a wave spring and dual-scraper, efficiently cleans the ball surface, maintaining pristine sealing integrity.
Our dual-sealing system is meticulously crafted to ensure leakage prevention by isolating the flow from the spring, guaranteeing an exceptional leakage class.
Experience the unparalleled sealing stability and reliability of our advanced soft seat design.
With a meticulously designed draining and sweeping function, our valve effectively prevents jamming, ensuring seamless operation through thorough cleaning.
Engineered to comply with API 607 standards, these valves are equipped with fireproof and anti-static capabilities, ensuring exceptional safety and performance.
SNT Ball Valves are exquisitely crafted to adhere to an array of prestigious international standards, such as ASME B16.34-2009, ASME B16.10-2000, and API 589-2009.
