Introducing the unparalleled High Performance Soft Seated Ball Valve series brought to you by SNT Machinery (Qingdao) Co., Ltd. These valves are meticulously crafted to deliver unparalleled Zero-Leakage performance, making them an ideal choice for a wide array of high-temperature and high-pressure service applications. Experience engineering excellence tailored specifically for demanding environments.
With unmatched craftsmanship, each valve's ball and seat are meticulously reinforced with state-of-the-art, advanced hard coatings of either chrome carbide or tungsten carbide. This robust fortification bestows exceptional resistance against both erosion and abrasion, significantly boosting the valve's longevity and reliability, even in the most challenging conditions.
Our exceptional SNT High Performance Soft Seated Ball Valves boast a cutting-edge HVOF coating system, ensuring premier performance. Each valve undergoes a meticulous mate-lapping process using innovative proprietary techniques, guaranteeing flawless 100% sealing. The advanced live loading feature ensures zero emissions, while the ball's continuous contact with the seat effectively wipes away contaminants. This revolutionary self-cleaning mechanism prevents particle interference and potential damage, making these valves an ideal choice for slurry and abrasive service applications, ensuring optimal performance and reliability.
Our innovative special packing combination is engineered to not only meet stringent emission requirements of 100 ppm but also reduce stem friction by an impressive 20%, epitomizing efficiency and environmental responsibility.
Expertly crafted with an anti-blowout design, our valves ensure the stem is securely retained, preventing blowout and potential case damage, thereby enhancing safety and durability.
Featuring a sophisticated seat ring structure with a wave spring and dual-scraper technology, our design effectively cleans the ball surface, maintaining superior sealing integrity and performance.
Our advanced dual-sealing mechanism ensures leakage integrity by preventing flow contact with the spring, guaranteeing optimal leakage class and reliability.
Experience superior stability and reliability with our soft seat design, which offers consistent and dependable sealing performance.
Ingeniously designed with draining and sweeping functionalities, our valves prevent jamming by efficiently cleaning, ensuring seamless operation and longevity.
Engineered to comply with API 607 standards, our valves offer exceptional fire-proof and anti-static capabilities, ensuring safety and compliance in demanding environments.
SNT Ball Valves are crafted with precision and adhere to a broad spectrum of esteemed international standards, including ASME B16.34-2009, ASME B16.10-2000, and API 589-2009. This adaptable series is ideally suited for extensive applications across numerous sectors including petroleum, chemical industry, light industry, pharmaceuticals, paper-making, metallurgy, and power stations, ensuring unmatched performance and reliability in every application.
