Product Description

^{Introducing the High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. Exquisitely crafted and meticulously engineered, these valves are designed to deliver outstanding and reliable Zero-Leakage performance in a wide range of challenging high-temperature and high-pressure service applications.
Crafted with unmatched precision, the ball and seat of these extraordinary valves are reinforced with cutting-edge hard coatings of chrome carbide or tungsten carbide. This superior fortification provides exceptional resistance against both erosion and abrasion, significantly enhancing the longevity and reliability of the valves.
Our SNT High Performance Soft Seated Ball Valves are enhanced with a state-of-the-art HVOF coating system. Each valve is subjected to meticulous mate-lapping using proprietary techniques to ensure a flawless 100% sealing. The innovative live loading feature guarantees zero emissions, while the ball maintains constant contact with the seat, effectively wiping away contaminants. This advanced self-cleaning mechanism prevents interference and potential damage from particles, making these valves the optimal choice for slurry and abrasive service applications.}

Structure Features

 

<sup>The innovative special packing combination not only meets the stringent emission requirements of 100 ppm but also ingeniously reduces friction by an impressive 20%, ensuring superior performance and longevity for the stem.

With an advanced anti-blowout design, this valve expertly prevents the stem from being expelled, thereby safeguarding against potential damage and ensuring robust reliability.

Ingeniously engineered, the seat ring's wave spring and dual-scraper structure meticulously clean the ball surface, maintaining impeccable sealing integrity over time.

The dual-sealing technology guarantees unparalleled leakage prevention by ensuring the fluid flow avoids contact with the spring, thereby achieving the highest leakage class standards.</sup>

The sealing performance of the soft seat is engineered for enhanced stability and reliability, promising consistent and trustworthy operation.

The intelligent design of draining and sweeping features prevents the valve from becoming jammed by efficiently cleaning, ensuring seamless and uninterrupted operation.

This product is fully compliant with API 607 standards, featuring fire-proof and anti-static capabilities for maximized safety and reliability in harsh environments.
