Presenting the High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. These valves are meticulously crafted to set a new standard in excellence, delivering unparalleled Zero-Leakage performance across a wide range of challenging high-temperature and high-pressure service applications.
Built with extraordinary precision, the ball and seat of these sophisticated valves are fortified with cutting-edge hard coatings of chrome carbide or tungsten carbide. This remarkable enhancement provides unrivaled resistance to both erosion and abrasion, significantly boosting the valve's lifespan and reliability.
Our SNT High Performance Soft Seated Ball Valves are infused with a revolutionary HVOF coating system. Through meticulous mate-lapping and proprietary techniques, each valve achieves a seamless 100% sealing. The innovative live loading feature ensures zero emissions, maintaining the ball's continuous contact with the seat to effectively cleanse contaminants. This advanced self-cleaning mechanism actively prevents interference and damage from abrasive particles, making these valves the ideal choice for slurry and demanding abrasive service applications.
Structure Features
Our innovative special packing combination is engineered to not only meet stringent emission requirements of 100 ppm but also ingeniously reduce friction by an impressive 20% to the stem, ensuring peak performance.
The robust design of our anti-blowout feature serves as a safeguard, effectively preventing the stem from blowing out and averting potential damage to the casing.
Featuring an advanced seat ring structure with wave spring and dual-scraper technology, our valve design excels in cleaning the ball surface, thus maintaining excellent sealing performance.
Our dual-sealing mechanism is meticulously crafted to ensure superior leak-proof capabilities by ingeniously preventing the flow from contacting the spring, thereby guaranteeing high leakage class.
Experience the remarkable stability and reliability of our soft seat sealing performance, designed for optimal functionality and durability.
The expertly designed draining and sweeping system effectively prevents the valve from jamming, ensuring seamless operation through thorough cleaning.
Crafted in compliance with API 607 standards, our valves incorporate essential fire-proof and anti-static functions, offering unmatched safety and reliability.
SNT Ball Valves are precision-engineered to meet a wide array of international standards, including the esteemed ASME B16.34-2009, ASME B16.10-2000, and API 589-2009. This adaptable series is extensively employed across diverse sectors such as the petroleum, chemical industry, light industry, pharmaceuticals, paper-making, metallurgy, and power stations.
