Introducing the High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. Expertly crafted, these valves boast an exceptional Zero-Leakage performance, specifically designed to excel under the demanding conditions of high-temperature and high-pressure service applications.
With unparalleled attention to detail, the ball and seat of these valves are expertly reinforced with cutting-edge hard coatings of either chrome carbide or tungsten carbide. This robust enhancement provides extraordinary resistance against erosion and abrasion, significantly boosting both durability and reliability.
Our SNT High Performance Soft Seated Ball Valves feature a revolutionary HVOF coating system. Each valve undergoes exacting mate-lapping employing exclusive techniques to ensure an immaculate 100% seal. The advanced live loading capability assures zero emissions, with the ball maintaining constant contact with the seat to efficiently clear away contaminants. This sophisticated self-cleaning mechanism prevents the intrusion and harm from particles, making these valves the ultimate solution for slurry and abrasive service applications.
Experience the innovation with our special packing combination, meticulously crafted to meet the rigorous emission requirement of 100 ppm. This advanced design not only ensures regulatory compliance but also ingeniously reduces stem friction by an impressive 20%, enhancing operational efficiency.
Our anti-blow out design is a testament to safety and reliability. It effectively prevents the stem from being blown out, thereby safeguarding against potential damage and ensuring the longevity of the valve.
The ingenious structure of the seat ring, featuring a wave spring and dual-scraper, is designed to maintain pristine ball surface by actively cleaning it. This ensures consistent sealing performance and optimal functionality.
Dual-sealing technology provides an exceptional leakage class assurance by cleverly preventing the flow from contacting the spring, delivering unmatched sealing reliability.
The sealing performance of our soft seat is meticulously engineered to be exceptionally stable and reliable, offering peace of mind through consistent and dependable operation.
Our innovative draining and sweeping design is engineered to prevent valve jamming. It achieves this by efficiently cleaning, ensuring seamless operation and reducing downtime.
Compliant with API 607 standards, our product is fortified with fire-proof and anti-static functions. This ensures that our valves offer robust protection and enhanced safety in all operational environments.
