Expertly crafted with extraordinary precision, the ball and seat of these valves are fortified with highly advanced hard coatings of either chrome carbide or tungsten carbide. This premium reinforcement guarantees an exceptional level of resistance against both erosion and abrasion, thereby significantly enhancing their durability and dependability.
Our SNT High Performance Soft Seated Ball Valves are enhanced with a cutting-edge HVOF coating system. Each valve undergoes meticulous mate-lapping through proprietary techniques to ensure a perfect 100% seal. With an innovative live loading feature that promises zero emissions, the ball maintains constant contact with the seat, effectively wiping away any contaminants. This groundbreaking self-cleaning system prevents interference and damage from particles, making these valves an ideal choice for handling slurry and abrasive service applications.
Our anti-blowout design is engineered to prevent any accidental ejection of the stem, safeguarding against potential damage and ensuring uninterrupted performance. This crucial feature bolsters the robustness and reliability of the entire assembly.
Crafted with precision, the seat ring structure features a wave spring and dual-scraper arrangement. This intelligent design effectively cleans the ball surface, ensuring optimal sealing performance and maintaining a pristine operational environment.
Our dual-sealing mechanism guarantees an impeccable leakage class by ingeniously preventing the flow from contacting the spring. This advanced feature ensures the highest possible standards of leak prevention.
Innovatively designed, the draining and sweeping features of our valves prevent any potential jamming, maintaining optimal functionality through efficient cleaning. This ensures long-term reliability and performance consistency.
Our valves are fully compliant with API 607 standards, equipped with essential fire-proof and anti-static functions. These features ensure that our products provide the highest level of safety and reliability, even in the most demanding environments.
Their Outstanding Features Include:
Streamlined design for effortless disassembly, allowing for quick and easy access to internal components, dramatically reducing service time.
Designed with ease of maintenance in mind, our ball valves feature a non-tight fit design that facilitates quick servicing, minimizing downtime during periodic maintenance, making them an ideal choice for industries seeking efficiency and reliability.
Cutting-edge sealing technology for maximum security, ensuring every valve operates flawlessly under high pressure and extreme conditions.
The multi-layer sealing of stem and body delivers dual protection through a combination of O-ring and graphite or PTFE, ensuring exceptional sealing performance under even the most demanding environments.
This innovative design meets the rigorous TA-Luft/Shell SPE 77/312 standards, ensuring compliance with environmental and safety regulations.
Extended Service Life for Superior Cost-Efficiency
Our metal seated ball valves undergo advanced processing techniques such as spray welding, spraying, and fusion welding. This guarantees a hardness range of HRC58-73 and a binding force of 80-40MPa, with an impressive on-off cycle lifespan exceeding 100,000 operations and a leakage class of ANSI VI, promising durability and reliability that contribute to long-term savings.
Modular Design for Enhanced Convenience
The modular inner sealing design allows for easy interchangeability between soft and metal seats, ensuring flexibility and reliability, catering to a wide range of applications and user needs.
Varied Connection Types for User Convenience
Our valves are available in various connection types, including flanged (RF, FF, FM, G, RJ), screw-thread, and BW, all of which conform to international standards, providing seamless and user-friendly integration, ensuring that they fit perfectly into your existing pipeline systems.
