Product Description

 

Introducing the unparalleled series of Zero-Leakage ball valves by SNT Machinery. Expertly designed for a multitude of demanding service applications, these valves excel in conditions characterized by high temperature and high pressure, ensuring flawless performance.
Our ball and seat are fortified with superior hard coatings of chrome carbide or tungsten carbide, offering exceptional resistance to erosion and abrasion. This meticulous construction guarantees durability and reliability under the most rigorous conditions.
Utilizing the advanced HVOF coating system, SNT Machinery masterfully crafts each component with our proprietary mate-lapped technique, delivering an impeccable 100% sealing solution. The innovative live loading mechanism further ensures zero emissions. Unique in its design, the ball continuously maintains contact with the seat, effectively eliminating contaminants with a self-cleaning action. This feature is paramount for preventing interference and damage, making this valve an optimal choice for slurry and abrasive services.
