Introducing the High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd.! These valves are a testament to meticulous engineering, offering unparalleled Zero-Leakage performance in a wide range of rigorous high-temperature and high-pressure service applications. This exceptional series is designed to meet the most demanding industrial needs with precision and reliability.
Engineered with unmatched precision and skill, the ball and seat of these valves are expertly reinforced with the most advanced hard coatings available, such as chrome carbide or tungsten carbide. This superior level of fortification guarantees exceptional resistance to both erosion and abrasion, thereby significantly enhancing the longevity and reliability of the valves.
Our SNT High Performance Soft Seated Ball Valves feature an innovative HVOF coating system, ensuring superior quality and performance. Each valve undergoes a meticulous mate-lapping process using our proprietary techniques, guaranteeing a flawless 100% sealing capability. The state-of-the-art live loading feature ensures zero emissions, with the ball maintaining constant contact with the seat to effectively wipe away contaminants. This advanced self-cleaning mechanism prevents particle interference and damage, making these valves the ideal choice for slurry and abrasive service applications.
A unique and innovative packing combination successfully meets the stringent emission requirements of 100 ppm and simultaneously reduces friction by an impressive 20%, enhancing the performance of the stem.
Ingeniously designed with an anti-blowout feature, this valve prevents the stem from ejecting, effectively averting potential damage.
The seat ring's advanced wave spring and dual-scraper construction meticulously clean the ball surface, ensuring impeccable and consistent sealing.
Our dual-sealing mechanism confidently guarantees leakage prevention by expertly isolating the flow from the spring, maintaining the highest leakage class standards.
Enjoy unparalleled stability and reliability in sealing performance, courtesy of our meticulously engineered soft seat design.
The thoughtfully designed draining and sweeping functions effectively prevent the valve from jamming, ensuring smooth operation through comprehensive cleaning.
Our valves comply with API 607 standards, offering robust fire-proof and anti-static capabilities to ensure safety and reliability.
SNT Ball Valves are meticulously crafted to meet and exceed a wide array of global standards. They adhere to rigorous specifications such as ASME B16.34-2009, ASME B16.10-2000, and API 589-2009. This versatile series is indispensable in diverse sectors including petroleum, chemical processing, light manufacturing, pharmaceuticals, paper production, metallurgy, and power generation.
Their Outstanding Features Include:
Streamlined and efficient design for effortless disassembly, ensuring smooth operations.
Crafted with user convenience at the forefront, our ball valves feature a non-tight fit design that simplifies servicing. This innovative approach significantly reduces downtime during essential maintenance procedures.
Revolutionary sealing technology ensures maximum security and peace of mind.
The multi-layer sealing of stem and body provides unparalleled protection by combining an O-ring with graphite or PTFE. This delivers an exceptional sealing performance, setting new industry standards.
This pioneering design rigorously complies with the TA-Luft/Shell SPE 77/312 standards.
Extended Service Life for Superior Cost-Efficiency
Our metal seated ball valves undergo sophisticated processing techniques including spray welding, spraying, and fusion welding. This process ensures a remarkable hardness range of HRC58-73 and a robust binding force of 80-40MPa. They boast an incredible on-off cycle lifespan of over 100,000 operations while maintaining a leakage class of ANSI VI.
Modular Design for Enhanced Convenience
The modular inner sealing design offers easy interchangeability between soft and metal seats. This ensures flexibility, reliability, and tailored use solutions.
Varied Connection Types for User Convenience
