Product Description

Experience the pinnacle of precision with our series of Zero-Leakage ball valves, expertly crafted for use across a variety of demanding service applications. Engineered to withstand both high temperature and high pressure environments, these valves provide unparalleled reliability and safety.
Our ball valves feature balls and seats that are meticulously hard-coated with either chrome carbide or tungsten carbide. This advanced coating technology imparts exceptional resistance to erosion and abrasion, ensuring long-lasting durability and performance under extreme conditions.
At SNT Machinery, we employ cutting-edge HVOF coating systems. Our proprietary mate-lapping technique guarantees a flawless 100% seal, while live loading ensures zero emissions. The innovative design keeps the ball constantly seated, effectively wiping away contaminants. This self-cleaning feature significantly reduces interference and potential damage, making these valves ideal for both slurry and abrasive service environments. Trust in our robust solutions for superior performance.
