Product Description

^{Introducing the High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. Masterfully engineered to surpass industry standards, these valves offer impeccable Zero-Leakage performance, seamlessly adapting to diverse high-temperature and high-pressure service applications, delivering reliability and efficiency where it matters most.
Crafted with unmatched precision, the ball and seat of these valves are fortified with state-of-the-art coatings of chrome carbide or tungsten carbide. This robust enhancement ensures superior resistance to erosion and abrasion, significantly boosting the product's lifespan and dependability.
Our SNT High Performance Soft Seated Ball Valves feature a groundbreaking HVOF coating system. Each valve is meticulously mate-lapped using exclusive techniques to ensure an impeccable 100% sealing. The pioneering live loading feature guarantees zero emissions, maintaining constant contact between the ball and seat to effectively clear contaminants. This innovative self-cleaning mechanism not only prevents particle interference but also protects against damage, making these valves an ideal choice for challenging slurry and abrasive service applications.}

Structure Features

 

<sup>Featuring a specialized packing combination, our valves are engineered to meet strict emission requirements of 100 ppm while simultaneously reducing stem friction by an impressive 20%. This innovative design ensures optimal performance and longevity even under demanding conditions.

An advanced anti-blowout design is integrated to safeguard against stem ejection, preventing potential damage and ensuring operational safety and reliability.

The ingenious seat ring structure, equipped with a wave spring and dual-scraper, effectively cleans the ball surface to maintain excellent sealing. This ensures consistent performance and extends the valve's life span.

Dual-sealing technology is expertly crafted to achieve superior leakage protection by preventing the flow from contacting the spring, thereby ensuring a robust leakage class.</sup>

The soft seat's sealing capability is unwaveringly stable and dependable, offering enhanced reliability in diverse environments.

A thoughtfully designed draining and sweeping system is incorporated to avert any potential jamming, keeping the valve clean and fully operational.

Our valves are fully compliant with API 607 standards, delivering essential fire-proof and anti-static functionalities for heightened safety and dependability.
