Product Description

^{Introducing the High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. Engineered with meticulous precision, these valves are designed to deliver outstanding Zero-Leakage performance that excels in a myriad of high-temperature and high-pressure service applications, ensuring unrivaled operational excellence and reliability.
Forged with unmatched precision, the ball and seat of these exceptional valves are enhanced with advanced hard coatings of chrome carbide or tungsten carbide. This robust fortification provides exceptional resistance to both erosion and abrasion, thereby significantly enhancing their longevity, robustness, and unparalleled reliability.
Our SNT High Performance Soft Seated Ball Valves feature an advanced HVOF coating system, representing the pinnacle of modern valve technology. Each valve undergoes meticulous mate-lapping using proprietary techniques to ensure a flawless 100% sealing. The innovative live loading feature guarantees zero emissions, while maintaining constant contact between the ball and seat, effectively eliminating contaminants. This cutting-edge self-cleaning mechanism prevents interference and damage from particles, making these valves the ideal choice for slurry and abrasive service applications, ensuring a seamless and efficient operation.}

Structure Features

 

<sup>This innovative packing combination not only meets stringent emission standards of 100 ppm but also significantly lowers friction to the stem by an impressive 20%, enhancing the valve's efficiency and durability.

Ingeniously designed with an anti-blow out feature, this valve ensures that the stem remains securely in place, preventing any potential damage from unexpected blowouts.

Featuring an advanced seat ring structure with a wave spring and dual-scraper, this system effectively cleans the ball surface while ensuring robust sealing, delivering exceptional performance every time.

The dual-sealing mechanism guarantees superior leakage prevention, ingeniously designed to prevent the flow from contacting the spring, thus ensuring a high leakage class.</sup>

With its reliable and stable soft seat sealing performance, this valve offers unmatched dependability, maintaining consistency even in demanding conditions.

Our thoughtful design integrates draining and sweeping functions, effectively preventing the valve from getting jammed and ensuring it remains clean and operational.

Adhering to the rigorous API 607 standards, this valve is equipped with fire-proof and anti-static features, ensuring safety and reliability in critical applications.
