These valves are a masterpiece of meticulous engineering, delivering an extraordinary Zero-Leakage performance across a myriad of high-temperature and high-pressure service scenarios. Experience reliability like never before.
Engineered with unmatched precision and care, the ball and seat of our valves are strengthened with advanced hard coatings, featuring either chrome carbide or tungsten carbide. This robust reinforcement provides exceptional resistance to erosion and abrasion, significantly extending the product's lifespan and reliability. Discover durability redefined.
SNT's High Performance Soft Seated Ball Valves are equipped with a state-of-the-art HVOF coating system. Each valve is meticulously mate-lapped with proprietary techniques, ensuring a flawless 100% sealing effectiveness. The innovative live loading system guarantees zero emissions, maintaining the ball's constant contact with the seat to effectively remove contaminants. This revolutionary self-cleaning mechanism prevents damage from particles, thereby making these valves the ultimate choice for demanding slurry and abrasive service applications. Elevate your operational efficiency with our groundbreaking technology.
Our innovative special packing combination is engineered to flawlessly meet the stringent emission requirement of 100 ppm, while simultaneously reducing friction by an impressive 20% to the stem, ensuring optimal performance and longevity.
The meticulously crafted anti-blow out design effectively prevents the stem from blowing out, thereby safeguarding against potential damage to the case and ensuring operational integrity.
The advanced structure of the seat ring, equipped with a wave spring and dual-scraper, is designed to meticulously clean the ball surface, thereby maintaining impeccable sealing and enhancing operational efficiency.
With our dual-sealing technology, we confidently guarantee superior leakage class by ingeniously preventing the flow from contacting the spring, securing unparalleled reliability.
The sealing performance of our soft seat is crafted for exceptional stability and reliability, ensuring your system's integrity and peace of mind.
Our state-of-the-art draining and sweeping design is engineered to effectively prevent the valve from jamming, offering unparalleled cleaning capabilities and ensuring smooth operation.
Our product proudly complies with API 607 standards, boasting superior fire-proof and anti-static functionalities for your utmost safety and assurance.
SNT Ball Valves are precisely crafted to adhere to a wide range of esteemed international standards, including ASME B16.34-2009, ASME B16.10-2000, and API 589-2009.
