Product Description

Introducing our exceptional line of Zero-Leakage ball valves, expertly crafted for a wide range of service applications that demand high efficiency under extreme conditions, including elevated temperatures and pressures. Experience unparalleled reliability and unyielding performance in every use.
Our cutting-edge ball valves feature a robust and resilient design, with both the ball and seat meticulously hard-coated using premium chrome carbide or tungsten carbide. This ensures superior resistance to erosion and abrasion, guaranteeing long-lasting durability and performance in challenging environments.
At SNT Machinery, we harness the power of the advanced HVOF coating system to deliver an unmatched sealing solution. Our proprietary mate-lapping technique ensures a flawless 100% seal, while our innovative live loading mechanism eliminates emissions entirely. By keeping the ball in constant contact with the seat, our design effectively wipes away contaminants, enabling self-cleaning properties that prevent interference and potential damage. These features make our valves exceptionally suited for both slurry and abrasive services, providing reliable and efficient operation.
