Product Description
Introducing the High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd.! These valves are a testament to meticulous engineering, offering unparalleled Zero-Leakage performance in a wide range of rigorous high-temperature and high-pressure service applications. This exceptional series is designed to meet the most demanding industrial needs with precision and reliability.
Engineered with unmatched precision and skill, the ball and seat of these valves are expertly reinforced with the most advanced hard coatings available, such as chrome carbide or tungsten carbide. This superior level of fortification guarantees exceptional resistance to both erosion and abrasion, thereby significantly enhancing the longevity and reliability of the valves.
Our SNT High Performance Soft Seated Ball Valves feature an innovative HVOF coating system, ensuring superior quality and performance. Each valve undergoes a meticulous mate-lapping process using our proprietary techniques, guaranteeing a flawless 100% sealing capability. The state-of-the-art live loading feature ensures zero emissions, with the ball maintaining constant contact with the seat to effectively wipe away contaminants. This advanced self-cleaning mechanism prevents particle interference and damage, making these valves the ideal choice for slurry and abrasive service applications.Structure Features
A unique and innovative packing combination successfully meets the stringent emission requirements of 100 ppm and simultaneously reduces friction by an impressive 20%, enhancing the performance of the stem.
Ingeniously designed with an anti-blowout feature, this valve prevents the stem from ejecting, effectively averting potential damage.
The seat ring's advanced wave spring and dual-scraper construction meticulously clean the ball surface, ensuring impeccable and consistent sealing.
Our dual-sealing mechanism confidently guarantees leakage prevention by expertly isolating the flow from the spring, maintaining the highest leakage class standards.Enjoy unparalleled stability and reliability in sealing performance, courtesy of our meticulously engineered soft seat design.
The thoughtfully designed draining and sweeping functions effectively prevent the valve from jamming, ensuring smooth operation through comprehensive cleaning.
Our valves comply with API 607 standards, offering robust fire-proof and anti-static capabilities to ensure safety and reliability.Our Advantages
SNT Ball Valves are meticulously crafted to meet and exceed a wide array of global standards. They adhere to rigorous specifications such as ASME B16.34-2009, ASME B16.10-2000, and API 589-2009.
