Presenting the exquisite High Performance Soft Seated Ball Valve series from SNT Machinery (Qingdao) Co., Ltd. These valves are the epitome of precision engineering, offering phenomenal Zero-Leakage performance across an array of challenging high-temperature and high-pressure service environments.
Constructed with unparalleled attention to detail, the ball and seat assemblies in these valves are fortified with state-of-the-art hard coatings, utilizing either chrome carbide or tungsten carbide. This exceptional reinforcement provides remarkable resistance to both erosion and abrasion, significantly boosting durability and operational reliability.
Our SNT High Performance Soft Seated Ball Valves are equipped with an advanced HVOF coating system. Each valve undergoes thorough mate-lapping coupled with unique proprietary techniques, ensuring a perfect 100% seal. The ingenious live loading feature delivers zero emissions, keeping the ball in seamless contact with the seat to efficiently clear away contaminants. This groundbreaking self-cleaning mechanism effectively prevents interference and damage from particles, making these valves an exceptional choice for slurry and abrasive service applications.
Our specialized packing combination is expertly engineered to meet stringent emission requirements of 100 ppm. It also innovatively reduces friction to the stem by an impressive 20%, ensuring smooth and efficient operation.
The anti-blowout design is meticulously crafted to prevent the stem from being expelled, thereby safeguarding the valve from potential damage and ensuring continued reliability in operation.
The intricate structure of the seat ring, featuring a wave spring and dual-scraper, is designed to meticulously clean the ball surface while maintaining a robust seal, ensuring long-lasting performance and efficiency.
Our dual-sealing mechanism is expertly designed to guarantee leakage protection by preventing flow from contacting the spring, thus ensuring superior sealing class and performance.
The sealing performance of our soft seat is engineered to be exceptionally stable and reliable, providing consistent and dependable results across a range of conditions.
Our advanced draining and sweeping design effectively prevents the valve from jamming, ensuring smooth operation by thoroughly cleaning and maintaining the system.
Engineered in compliance with API 607 standards, our valves boast fire-proof and anti-static features, ensuring safety and reliability in even the most demanding environments.
At SNT Machinery (Qingdao) Co., Ltd., our SNT Ball Valves are crafted with precision and adhere to an array of international standards, including ASME B16.34-2009, ASME B16.10-2000, and API 589-2009. This versatile series is extensively utilized across a wide spectrum of industries, from petroleum and chemical sectors to light industry, pharmaceuticals, paper-making, metallurgy, and power stations, offering unparalleled reliability and quality.
Their Outstanding Features Include:
Streamlined design for effortless disassembly.
Meticulously engineered with a focus on ease of maintenance, our ball valves incorporate a non-tight fit design. This feature allows for swift and seamless servicing, drastically reducing downtime during essential periodic maintenance checks.
Cutting-edge sealing technology for maximum security.
Our innovative multi-layer sealing system for the stem and body provides dual protection by combining the strengths of O-ring and graphite or PTFE. This ensures remarkable sealing performance, safeguarding against leaks and enhancing operational integrity.
This pioneering design meets the stringent TA-Luft/Shell SPE 77/312 standards, guaranteeing superior environmental compliance and operational safety.
Extended Service Life for Superior Cost-Efficiency
Our metal seated ball valves are subjected to advanced processing techniques, including spray welding, spraying, and fusion welding. This results in a formidable hardness range of HRC58-73 and a binding force of 80-40MPa. With an impressive capability to endure over 100,000 on-off cycles and an exceptional leakage class of ANSI VI, these valves promise a long-lasting service life that greatly enhances cost efficiency.
Modular Design for Enhanced Convenience
The innovative modular inner sealing design facilitates easy interchangeability between soft and metal seats, ensuring both flexibility and dependability for diverse applications.
Varied Connection Types for User Convenience
Our valves offer a variety of connection types, including flanged (RF, FF, FM, G, RJ), screw-thread, and BW. Each option conforms to international standards, ensuring seamless integration and a user-friendly experience.
