Product Description

^{Introducing the High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. These valves are meticulously engineered to deliver unparalleled Zero-Leakage performance, regardless of the demanding high-temperature and high-pressure service applications they encounter. Trust in their stellar design and reliable operation to meet your flow management needs with ease and precision.
Crafted with unmatched precision, the ball and seat of these valves are fortified with advanced hard coatings of either chrome carbide or tungsten carbide. This supreme reinforcement provides exceptional resistance to both erosion and abrasion, significantly enhancing the durability and reliability of the valves over time. Experience longevity and robust performance with our expertly designed solutions.
Our SNT High Performance Soft Seated Ball Valves feature a groundbreaking HVOF coating system, setting new standards in valve technology. Every valve is subjected to meticulous mate-lapping using proprietary techniques, ensuring an impeccable 100% sealing performance. The innovative live loading feature guarantees zero emissions, maintaining the ball in constant contact with the seat to effectively remove contaminants. This revolutionary self-cleaning mechanism prevents interference and damage from particles, making these valves the ultimate choice for handling slurry and abrasive service applications with confidence and efficiency.}

Structure Features

 

<sup>The specialized packing combination is engineered to meet stringent emission requirements of 100 ppm, while ingeniously reducing stem friction by an impressive 20%!

Our innovative anti-blowout design effectively prevents any stem blowout, safeguarding the valve from potential damage.
