Product Description

^{Introducing the High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. Expertly crafted and meticulously engineered, these valves are designed to deliver unparalleled Zero-Leakage performance, even in the most challenging high-temperature and high-pressure service applications.
Engineered with unrivaled precision, the ball and seat components of these valves are bolstered with state-of-the-art hard coatings of either chrome carbide or tungsten carbide. This exceptional reinforcement provides superior resistance against both erosion and abrasion, significantly enhancing the longevity and dependability of each valve.
Our SNT High Performance Soft Seated Ball Valves feature a cutting-edge HVOF coating system. Each valve is subjected to meticulous mate-lapping through proprietary techniques to ensure impeccable 100% sealing. With an innovative live loading feature, these valves guarantee zero emissions, keeping the ball in constant contact with the seat to effectively eliminate contaminants. This advanced self-cleaning mechanism prevents particle interference and damage, making these valves the ultimate choice for slurry and abrasive service applications.}
