Introducing the High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. Exquisitely designed and meticulously engineered, these valves are crafted to deliver unmatched Zero-Leakage performance, even under the most demanding high-temperature and high-pressure conditions. They stand as a testament to superior engineering, ensuring excellence across a multitude of service applications.
With unmatched precision, these valves are crafted with a ball and seat that are fortified using advanced hard coatings such as chrome carbide and tungsten carbide. This exceptional fortification provides remarkable resistance to erosion and abrasion, thereby significantly enhancing the longevity and reliability of the valve system.
At SNT, our High Performance Soft Seated Ball Valves are a testament to cutting-edge innovation, incorporating a state-of-the-art HVOF coating system. Each valve is subject to meticulous mate-lapping through our proprietary techniques, ensuring a flawless 100% sealing capability. Featuring an innovative live loading feature, these valves guarantee zero emissions. The ball remains in perpetual contact with the seat, continually wiping away contaminants. This advanced self-cleaning mechanism effortlessly prevents interference and damage from particles, making these valves the ultimate choice for applications involving slurry and abrasive materials.
Our innovative special packing combination not only meets the stringent emission requirement of 100 ppm but also ingeniously reduces friction to the stem by an impressive 20%. Discover unparalleled efficiency combined with environmental responsibility.
Engineered with precision, the advanced anti-blowout design protects against stem displacement, preventing potential damage and ensuring long-lasting durability.
Featuring a cutting-edge seat ring design that incorporates a wave spring and dual-scraper mechanism to effectively clean the ball surface, these valves maintain impeccable sealing for optimal performance.
The dual-sealing technology is expertly crafted to ensure impeccable leak prevention by strategically keeping flow away from contact with the spring, thereby maintaining a superior leakage class.
Experience unmatched stability and reliability with our meticulously designed soft seat sealing performance, setting new standards in valve technology.
The innovative draining and sweeping design is thoughtfully engineered to prevent valve jamming, ensuring smooth operation by effectively cleaning potential blockages.
Strictly adhering to API 607 standards, these valves boast exceptional fire-proof and anti-static features, offering enhanced safety and security in demanding environments.
SNT Ball Valves are crafted with precision engineering and adhere to an array of international benchmarks, notably ASME B16.34-2009, ASME B16.10-2000, and API 589-2009. This adaptable series is extensively utilized across a diverse range of industries, including the realms of petroleum, chemical production, light manufacturing, pharmaceuticals, paper production, metallurgy, and power generation facilities.
Their Exceptional Features Encompass:
Sophisticated streamlined design enables effortless disassembly.
Our ball valves, crafted with maintenance simplicity in mind, boast a non-tight fit design that supports rapid servicing, thereby reducing downtime during routine maintenance checks and ensuring operational efficiency.
Pioneering sealing technology for ultimate security and peace of mind.
The multi-layer sealing system of the stem and body provides dual-layer protection through the integration of an O-ring alongside graphite or PTFE, ensuring unparalleled sealing performance and reliability.
This groundbreaking design conforms to the stringent TA-Luft/Shell SPE 77/312 standards.
Prolonged Service Life for Optimal Cost-Effectiveness
Our metal seated ball valves are subjected to advanced processing techniques, including spray welding, spraying, and fusion welding. This ensures a hardness range of HRC58-73 and a binding force between 80-40MPa, offering an astounding operating cycle lifespan surpassing 100,000 operations, with a leakage class rated at ANSI VI.
Modular Design for Superior Convenience
The modular inner sealing architecture permits seamless interchangeability between soft and metal seats, delivering both flexibility and steadfast reliability.
Diverse Connection Types for Enhanced User Convenience
