Introducing the unparalleled High Efficiency Soft Seated Trunnion Ball Valves for Water Treatment, a remarkable creation by SNT Machinery (Qingdao) Co., Ltd. These meticulously engineered valves are designed to deliver unmatched Zero-Leakage performance, tailored for a wide array of challenging high-temperature and high-pressure service applications.
These valves are crafted with an extraordinary level of precision, featuring ball and seat components that are reinforced with premium hard coatings of chrome carbide or tungsten carbide. This remarkable fortification provides exceptional resistance to both erosion and abrasion, significantly enhancing the valves' longevity and reliability, standing the test of time in demanding environments.
The SNT High Performance Soft Seated Ball Valves are a testament to innovation, equipped with a state-of-the-art HVOF coating system. Each valve undergoes meticulous mate-lapping using proprietary techniques that ensure flawless 100% sealing capability. The ingenious live loading feature guarantees zero emissions, with the ball consistently in contact with the seat for a self-cleaning action that effectively eliminates contaminants. This innovative mechanism not only prevents interference and damage from particles but also makes these valves the optimal choice for slurry and abrasive service applications, offering exceptional durability and performance.
Structure Features
Our cutting-edge packing combination is designed to surpass emission requirements, meeting the stringent standard of 100 ppm while ingeniously reducing stem friction by an impressive 20%.
Crafted with precision, our anti-blowout design ensures unparalleled safety by securely preventing the stem from any unintended ejection that might cause damage.
Featuring an innovative wave spring and dual-scraper seat ring structure, our design effectively cleans the ball surface, maintaining impeccable sealing integrity.
The dual-sealing mechanism is meticulously engineered to uphold leakage standards by strategically preventing the spring from coming into contact with the flow.
Enjoy the peace of mind with our soft seat's remarkably stable and reliable sealing performance, crafted for excellence.
Our advanced draining and sweeping design adeptly prevents jamming, ensuring the valve remains clean and fully operational.
Conforming to the rigorous API 607 standards, our product is equipped with robust fire-proof and anti-static functionalities for maximum safety.
SNT Ball Valves are expertly crafted to meet a wide array of international standards, including ASME B16.34-2009, ASME B16.10-2000, and API 589-2009. This adaptable series is extensively utilized in numerous industries, such as petroleum, chemical processing, light manufacturing, pharmaceuticals, paper production, metallurgy, and power generation.
