Product Description

^{Introducing the High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. Experience the pinnacle of engineering excellence with our meticulously crafted valves, engineered to deliver superior Zero-Leakage performance across a broad spectrum of demanding high-temperature and high-pressure service applications.
Crafted with unmatched precision, the ball and seat of these valves are fortified with cutting-edge hard coatings of chrome carbide or tungsten carbide. This advanced reinforcement ensures exceptional resistance to erosion and abrasion, significantly enhancing the valve's longevity and unwavering reliability.
Our SNT High Performance Soft Seated Ball Valves feature a state-of-the-art HVOF coating system. Each valve is meticulously matelapped using proprietary techniques, guaranteeing a flawless 100% sealing capability. The ingenious live loading feature ensures zero emissions, while the ball maintains continuous contact with the seat, effectively eliminating contaminants. This revolutionary self-cleaning mechanism prevents interference and damage from particles, positioning these valves as the ultimate choice for slurry and abrasive service applications.}

Structure Features

 

<sup>Our special packing combination is engineered to not only meet the stringent emission requirements of 100 ppm but also ingeniously reduces the friction by an impressive 20% to the stem, ensuring optimal performance and longevity.

With a meticulously designed anti-blow out feature, our valves are crafted to prevent the stem from blowing out and causing damage, offering unparalleled safety and reliability.

The innovative structure of the seat ring, complete with a wave spring and dual-scraper design, ensures thorough cleaning of the ball surface while maintaining a robust seal, enhancing efficiency and performance.

Our dual-sealing technology is a hallmark of superior engineering, effectively ensuring the leakage class by preventing interaction between the flow and the spring, thereby safeguarding against leaks.</sup>

Experience stability and reliability like never before with our soft seat sealing performance, a promise of enduring quality and trust.

The cutting-edge draining and sweeping design of our valves prevents jamming by efficiently cleaning, ensuring smooth operation and maintenance-free longevity.

Our valves comply with the rigorous standards of API 607, featuring exceptional fire-proof and anti-static functions that fortify safety and enhance operational security.
