Product Description

^{Introducing the exceptional High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. Expertly crafted to perfection, these valves are a testament to engineering excellence, offering unparalleled Zero-Leakage performance across a broad spectrum of demanding high-temperature and high-pressure service applications.
Masterfully designed with precision, each ball and seat within these valves is fortified with advanced hard coatings, utilizing premium chrome carbide or tungsten carbide. This superior enhancement provides exceptional resistance to erosion and abrasion, significantly extending the lifespan and ensuring unmatched reliability.
Our SNT High Performance Soft Seated Ball Valves are equipped with a revolutionary HVOF coating system. Every valve is subjected to meticulous mate-lapping with proprietary techniques, ensuring a perfect and flawless 100% sealing capability. Featuring an innovative live loading design, these valves guarantee zero emissions while maintaining constant contact between the ball and seat, efficiently wiping away contaminants. This state-of-the-art self-cleaning mechanism prevents any interference and mitigates damage from particles, making these valves ideally suited for slurry and abrasive service applications.}

Structure Features

 

<sup>Our specially engineered packing combination is meticulously crafted to meet rigorous emission requirements of 100 ppm, all while reducing friction to the stem by an impressive 20%.

The robust anti-blowout design ensures that the stem remains securely in place, safeguarding against any potential blowout-induced damage.

With an innovative seat ring structure featuring a wave spring and dual scraper, our design efficiently cleans the ball surface, ensuring a consistently reliable seal.

Our dual-sealing capabilities provide unparalleled leakage protection, strategically designed to ensure that the flow never contacts the spring, thereby maintaining optimal sealing integrity.</sup>

Experience the exceptional stability and reliability of our soft seat's sealing performance, engineered for superior durability.

Ingeniously designed draining and sweeping features work harmoniously to prevent valve jamming, ensuring seamless cleaning and operation.

Fully compliant with API 607 standards, our product boasts fire-proof and anti-static functionalities, providing robust safety and performance.
