Crafted with unmatched precision, the ball and seat of these valves are fortified with state-of-the-art coatings of chrome carbide or tungsten carbide. This robust enhancement ensures superior resistance to erosion and abrasion, significantly boosting the product's lifespan and dependability.
Our SNT High Performance Soft Seated Ball Valves feature a groundbreaking HVOF coating system. Each valve is meticulously mate-lapped using exclusive techniques to ensure an impeccable 100% sealing. The pioneering live loading feature guarantees zero emissions, maintaining constant contact between the ball and seat to effectively clear contaminants. This innovative self-cleaning mechanism not only prevents particle interference but also protects against damage, making these valves an ideal choice for challenging slurry and abrasive service applications.
An advanced anti-blowout design is integrated to safeguard against stem ejection, preventing potential damage and ensuring operational safety and reliability.
The ingenious seat ring structure, equipped with a wave spring and dual-scraper, effectively cleans the ball surface to maintain excellent sealing. This ensures consistent performance and extends the valve's life span.
Dual-sealing technology is expertly crafted to achieve superior leakage protection by preventing the flow from contacting the spring, thereby ensuring a robust leakage class.
A thoughtfully designed draining and sweeping system is incorporated to avert any potential jamming, keeping the valve clean and fully operational.
Our valves are fully compliant with API 607 standards, delivering essential fire-proof and anti-static functionalities for heightened safety and dependability.
Their Outstanding Features Include:
Streamlined design for effortless disassembly.
Designed for ease of maintenance, our ball valves boast a non-tight fit design which facilitates quick servicing and minimizes downtime during periodic maintenance, ensuring your operations remain smooth and uninterrupted.
Cutting-edge sealing technology for maximum security.
The multi-layer sealing of stem and body provides dual protection using a combination of O-ring and graphite or PTFE, delivering unmatched sealing performance that stands the test of time.
This innovative design is crafted to meet the rigorous TA-Luft/Shell SPE 77/312 standards, ensuring compliance and peace of mind.
Extended Service Life for Superior Cost-Efficiency
Our metal seated ball valves are subjected to advanced processing techniques such as spray welding, spraying, and fusion welding, ensuring a robust hardness range of HRC58-73 and a binding force of 80-40MPa. Boasting an impressive on-off cycle lifespan exceeding 100,000 operations and a leakage class of ANSI VI, these valves promise extraordinary durability and reliability.
Modular Design for Enhanced Convenience
The modular inner sealing design allows seamless interchangeability between soft and metal seats, offering flexibility and reliability that adapts to your specific needs with ease.
Varied Connection Types for User Convenience
Our valves are offered in a variety of connection types, including flanged (RF, FF, FM, G, RJ), screw-thread, and BW, all conforming to international standards. This guarantees seamless, user-friendly integration and adaptability in diverse settings.
