Product Description

 

Introducing our premier series of Shutoff Ball Valves, engineered with precision for Zero-Leakage performance across diverse service applications. Whether dealing with high temperature or high pressure environments, our ball valves promise unwavering reliability.
Crafted for superior durability, the ball and seat of our valves are fortified with advanced hard coatings of chrome carbide or tungsten carbide. This innovation equips our valves with exceptional resistance against erosion and abrasion, ensuring longevity and performance.
At SNT Machinery (Qingdao) Co., Ltd., our cutting-edge HVOF coating system stands at the forefront of industrial technology. Utilizing our proprietary mate-lapping techniques, we guarantee 100% sealing efficiency. The live loading feature ensures zero emissions, while the ball's consistent contact with the seat prevents contamination build-up. This ingenious self-cleaning action effectively guards against interference and damage, making these valves ideally suited for handling slurry and abrasive services with unmatched precision.
