Introducing the High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. These valves are meticulously engineered to provide phenomenal Zero-Leakage performance, even in the most challenging high-temperature and high-pressure service environments. Experience the excellence and reliability that set these valves apart.
Crafted with unparalleled precision, the ball and seat of these valves are fortified with advanced, hard coatings using either chrome carbide or tungsten carbide. This superior protection offers remarkable resistance to both erosion and abrasion, ensuring extended longevity and unwavering reliability for demanding applications.
Our SNT High Performance Soft Seated Ball Valves feature an advanced HVOF coating system, ensuring unparalleled performance. Every valve undergoes meticulous mate-lapping with proprietary techniques to achieve an impeccable 100% sealing. The innovative live loading capability guarantees zero emissions, while the ball continuously contacts the seat to effectively remove contaminants. This state-of-the-art self-cleaning mechanism prevents particle interference and damage, making these valves the ultimate choice for slurry and abrasive service applications.
Our exceptional packing combination is engineered to surpass emission standards with an impressive threshold of 100 ppm. Simultaneously, it minimizes friction by 20%, ensuring a smooth operation for the stem.
Ingeniously designed with an anti-blowout feature, this product effectively prevents stem blowout and averts potential damage to the casing.
The innovative seat ring structure, featuring a wave spring and dual-scraper, ensures the ball surface remains pristine while maintaining a robust seal.
Our dual-sealing technology ensures a superior leakage class by ingeniously preventing the flow from contacting the spring.
The soft seat's sealing performance is exceptionally stable and reliable, providing unparalleled confidence in its durability.
Our expertly designed draining and sweeping mechanism effectively safeguards the valve from jamming by thoroughly cleaning it.
Adhering to API 607 standards, our product boasts fire-proof and anti-static functions, delivering peace of mind with enhanced safety features.
SNT Ball Valves are crafted with precision to adhere to an array of rigorous international standards, such as ASME B16.34-2009, ASME B16.10-2000, and API 589-2009. This adaptable and robust series is extensively utilized across a myriad of industries, including petroleum, chemical sectors, light industries, pharmaceuticals, paper-making, metallurgy, and power stations, providing unmatched efficiency and reliability.
Their Remarkable Features Include:
Elegant and streamlined design for hassle-free disassembly and reassembly.
Thoughtfully designed with maintenance convenience at its core, our ball valves boast a non-tight fit architecture, allowing for swift and simple servicing, significantly reducing downtime during routine maintenance tasks.
State-of-the-art sealing technology ensures optimal security and performance.
A sophisticated multi-layer sealing system within the stem and body offers dual protection using a combination of O-ring and either graphite or PTFE, ensuring unmatched sealing efficiency and reliability.
This forward-thinking design is built to meet the stringent TA-Luft/Shell SPE 77/312 standards, guaranteeing superior operational integrity.
Prolonged Service Life for Exceptional Cost-Effectiveness
Our metal seated ball valves are subjected to cutting-edge processing techniques, including spray welding, spraying, and fusion welding. This process achieves an impressive hardness range of HRC58-73 and a binding force of 80-40MPa, with an extraordinary operational lifespan surpassing 100,000 on-off cycles, and adhering to ANSI VI leakage class standards.
Innovative Modular Design for Increased Convenience
The modular inner sealing construction allows for seamless interchangeability between soft and metal seats, ensuring maximum flexibility and reliability in varied applications.
Diverse Connection Types for Enhanced User Convenience
Our valves are meticulously designed to offer a range of connection types, including flanged (RF, FF, FM, G, RJ), screw-thread, and BW. These conform to international standards, facilitating seamless integration and user-friendly operation.
