Introducing the High Performance Soft Seated Ball Valve series, crafted by the esteemed SNT Machinery (Qingdao) Co., Ltd. These meticulously engineered marvels ensure unparalleled Zero-Leakage performance, adeptly handling a wide array of challenging high-temperature and high-pressure service applications.
With unrivaled precision, the ball and seat of these exceptional valves are fortified with advanced hard coatings of either chrome carbide or tungsten carbide. This superior reinforcement provides extraordinary resistance against erosion and abrasion, significantly enhancing the valves' longevity and reliability.
Discover the SNT High Performance Soft Seated Ball Valves, featuring a cutting-edge HVOF coating system. Every valve undergoes a meticulous mate-lapping process using proprietary techniques to ensure a perfect 100% seal. The state-of-the-art live loading feature guarantees zero emissions, with the ball maintaining constant contact with the seat to effectively remove contaminants. This revolutionary self-cleaning mechanism prevents particle interference and damage, making these valves the ideal choice for abrasive and slurry service applications.
Structure Features
The unique special packing combination has been meticulously engineered to meet the stringent emission requirements of 100 ppm. In addition to this, it reduces friction by an impressive 20%, ensuring smooth operation and longevity of the stem.
Our revolutionary anti-blow out design is crafted to safeguard against potential stem blowout, thereby preventing any potential damage to the casing and maintaining the integrity of the system.
The advanced seat ring structure, featuring a wave spring and dual-scraper, is designed to efficiently clean the ball surface, thereby ensuring a pristine seal and optimal sealing performance.
Our innovative dual-sealing mechanism is designed to ensure the highest leakage class by preventing any flow from contacting the spring, thereby guaranteeing unmatched sealing integrity.
Experience superior stability and reliability with the soft seat's enhanced sealing performance, meticulously crafted for consistent results.
Ingeniously designed with integrated draining and sweeping functions, our valves are equipped to resist jamming by effectively cleaning and maintaining clear passageways.
Adhering to the stringent API 607 standards, our valves boast robust fire-proof and anti-static functionality, ensuring maximum safety and reliability in all operating conditions.
