Product Description

 

Discover the unparalleled excellence of our Zero-Leakage ball valves, expertly designed to thrive in a multitude of service applications, especially where high temperature and high pressure demand superior performance.
Engineered for endurance, the ball and seat are fortified with advanced hard coatings of chrome carbide or tungsten carbide, offering exceptional resistance to erosion and abrasion, ensuring lasting reliability.
At SNT Machinery, we utilize the cutting-edge HVOF coating system, complemented by our proprietary mate-lapping technique to guarantee 100% sealing. Enhanced with live loading, our valves promise zero emissions. The innovative design ensures the ball remains in perpetual contact with the seat, effectively wiping away contaminants. This self-cleaning mechanism not only prevents interference but also protects against potential damage from contaminants, making our valves the ideal choice for slurry and abrasive services.
