Product Description

^{Introducing the remarkable High Performance Soft Seated Ball Valve series brought to you by SNT Machinery (Qingdao) Co., Ltd. Expertly designed and meticulously engineered, these valves are your go-to solution for achieving unparalleled Zero-Leakage performance across a wide range of demanding high-temperature and high-pressure service scenarios.
Crafted with exceptional precision, every component of these valves, particularly the ball and seat, is fortified with cutting-edge hard coatings of chrome carbide or tungsten carbide. This meticulous fortification process guarantees outstanding resistance to erosion and abrasion, thereby significantly enhancing the valves' longevity and reliability, offering you peace of mind and unmatched performance.
Our SNT High Performance Soft Seated Ball Valves stand out with a state-of-the-art HVOF coating system. Each valve is subjected to meticulous mate-lapping using our proprietary techniques, ensuring a perfect 100% sealing capability. The innovative live loading feature further guarantees zero emissions, maintaining the ball's constant contact with the seat. This ingenious design effectively wipes away contaminants, thanks to the advanced self-cleaning mechanism. As a result, these valves are the ideal choice for slurry and abrasive service applications, as they proficiently prevent interference and damage caused by particles.}

Structure Features

 

<sup>Our innovative special packing combination is engineered to meet the strict emission requirement of 100 ppm, while impressively reducing stem friction by an impressive 20%, ensuring peak performance and longevity.

The expertly designed anti-blowout feature ensures utmost safety by preventing the stem from being ejected, thereby safeguarding against potential damage and enhancing operational security.

Our sophisticated seat ring structure, featuring a wave spring and dual-scraper, efficiently cleans the ball surface, maintaining impeccable sealing and performance standards.

With advanced dual-sealing technology, our product guarantees exceptional leakage protection by ensuring that the flow does not come into contact with the spring, delivering unmatched reliability.</sup>

Experience more stable and reliable sealing performance with our meticulously engineered soft seat design, setting a new standard in sealing excellence.

Ingeniously designed for optimal functionality, our draining and sweeping systems prevent valve jamming by thoroughly cleaning, ensuring seamless operation.
