Crafted with unrivaled precision, the ball and seat of these exceptional valves are reinforced with state-of-the-art hard coatings of chrome carbide or tungsten carbide. This superior fortification offers remarkable resistance to both erosion and abrasion, significantly enhancing the longevity and reliability of the valves. Experience the advantage of unparalleled durability and superior performance.
Our SNT High-Performance Soft Seated Ball Valves are enhanced with a cutting-edge HVOF coating system. Each valve is subjected to meticulous mate-lapping using proprietary techniques to ensure a flawless 100% sealing capability. The innovative live loading feature guarantees zero emissions, while the ball remains in constant, gentle contact with the seat, effectively wiping away contaminants. This pioneering self-cleaning mechanism prevents interference and potential damage from particles, making these valves the ideal choice for slurry and abrasive service applications. Trust in innovation that sets new standards of excellence.
Ingeniously designed anti-blow out feature ensures the stem remains securely in place, preventing any potential damage caused by blowouts.
The innovative seat ring structure, featuring a wave spring and dual-scraper mechanism, effectively cleans the ball surface while maintaining a robust seal.
Our advanced dual-sealing system assures the highest leakage class, cleverly designed to ensure the flow never comes into contact with the spring.
The efficient design of our draining and sweeping mechanism effectively prevents jamming by thoroughly cleaning the valve.
Engineered to meet API 607 standards, our valves offer outstanding fireproof and anti-static capabilities, ensuring safety and compliance.
Their Outstanding Features Include:
Streamlined design that ensures effortless disassembly with minimal effort.
Incorporating a non-tight fit design, our ball valves are engineered for easy maintenance. This feature enables quick servicing and reduces downtime during routine maintenance, enhancing operational efficiency.
State-of-the-art sealing technology ensures maximum security and reliability.
The multi-layer sealing system, employing a combination of O-ring and either graphite or PTFE, provides dual protection for the stem and body, delivering unparalleled sealing performance.
Our pioneering design satisfies the stringent TA-Luft/Shell SPE 77/312 standards, highlighting our commitment to excellence.
Extended Service Life for Superior Cost-Efficiency
Through advanced processes like spray welding, spraying, and fusion welding, our metal seated ball valves achieve a hardness range of HRC58-73, and a binding force of 80-40MPa. With a remarkable operational life exceeding 100,000 on-off cycles and a leakage class of ANSI VI, these valves exemplify longevity and cost efficiency.
Modular Design for Enhanced Convenience
With a modular inner sealing design, our valves allow seamless interchangeability between soft and metal seats, providing flexibility and dependable performance.
Varied Connection Types for User Convenience
Our valves come in diverse connection types such as flanged (RF, FF, FM, G, RJ), screw-thread, and BW. Each type adheres to international standards, ensuring seamless integration and user-friendly operation.
