Introducing the awe-inspiring High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. This collection is a testament to meticulous engineering, designed to deliver unparalleled Zero-Leakage performance. These valves excel in a myriad of high-temperature and high-pressure service applications, showcasing their versatility and robustness.
With unmatched precision, each valve's ball and seat are expertly crafted and fortified with cutting-edge hard coatings, such as chrome carbide or tungsten carbide. This advanced reinforcement ensures outstanding resistance to erosion and abrasion, significantly extending the valves' longevity and ensuring reliable performance in the most demanding environments.
The SNT High Performance Soft Seated Ball Valves are equipped with a revolutionary HVOF coating system. Every valve is painstakingly mate-lapped using exclusive proprietary techniques, assuring a flawless 100% sealing capability. The innovative live loading feature guarantees zero emissions and maintains constant contact between the ball and seat, effectively wiping away contaminants. This ingenious self-cleaning mechanism prevents interference and damage from particles, making these valves the optimal choice for challenging slurry and abrasive service applications.
Our special packing combination not only meets the strict emission requirements of 100 ppm but also ingeniously reduces stem friction by a remarkable 20%, ensuring enhanced performance and longevity.
The innovative anti-blowout design effectively safeguards against stem expulsion, thereby preventing potential damage and ensuring robust operational integrity.
Our meticulously engineered seat ring structure, featuring wave springs and dual scrapers, actively cleans the ball surface while maintaining an impeccable seal throughout its operation.
The dual-sealing mechanism ensures superior leak prevention by strategically isolating the flow from the spring contact, thereby upholding the highest leakage class standards.
With its unparalleled design, the sealing performance of our soft seat is consistently stable and dependable, offering unrivalled reliability.
Our advanced draining and sweeping design efficiently prevents valve jamming, ensuring optimal cleanliness and uninterrupted performance.
Engineered to comply with the rigorous API 607 standards, our valves boast fire-proof and anti-static capabilities, providing superior safety and resilience.
SNT Ball Valves are crafted with precision engineering to adhere to an array of international standards like ASME B16.34-2009, ASME B16.10-2000, and API 589-2009. This adaptable series is expertly utilized across a diverse range of industries, including petroleum, chemical industry, light industry, pharmaceuticals, paper-making, metallurgy, and power stations, ensuring comprehensive performance and versatility.
Their Distinctive and Outstanding Features Include:
A streamlined design that allows for effortless disassembly and reassembly.
Intelligently designed with maintenance ease at the forefront, our ball valves boast a non-tight fit design, enabling swift servicing to minimize downtime during scheduled maintenance, thus ensuring efficient operations.
State-of-the-art sealing technology that assures maximum security and leak-proof performance.
Featuring multi-layer sealing systems at the stem and body, our valves provide dual protection using an innovative blend of O-ring and graphite or PTFE, delivering unparalleled sealing efficiency.
Our groundbreaking design safely and effectively meets the stringent TA-Luft/Shell SPE 77/312 standards.
Extended Service Life for Unmatched Cost-Efficiency
Through advanced processing techniques such as spray welding, spraying, and fusion welding, our metal seated ball valves achieve a hardness level of HRC58-73 and a binding force between 80-40MPa. This results in a remarkable on-off cycle lifespan surpassing 100,000 operations, with a leakage class of ANSI VI, ensuring long-lasting performance and reliability.
Modular Design Providing Enhanced Operational Convenience
The modular inner sealing design offers easy interchangeability between soft and metal seats, guaranteeing flexibility, reliability, and seamless adaptability in diverse applications.
