Product Description

 

Discover the pinnacle of precision with our DN15 Full Shutoff Valve with Floating Ball series. Crafted to deliver impeccable zero-leakage performance across a vast array of service applications, these valves thrive even in the most extreme conditions of high temperature and high pressure.
Engineered for unrivaled durability, the ball and seat are enhanced with an advanced hard coating of chrome carbide or tungsten carbide. This state-of-the-art technology offers extraordinary resistance to erosion and abrasion, ensuring remarkably long-lasting performance.
Our SNT valves incorporate the state-of-the-art HVOF coating system. By employing our exclusive mate-lapping technique, we assure 100% sealing efficiency. Furthermore, live loading guarantees zero emissions, while the ball's constant contact with the seat effectively wipes away contaminants. This innovative self-cleaning mechanism protects the valve from damage and interference, making it exceedingly suitable for slurry and abrasive service applications.

 

 

 

 

 

Our Advantages

 

SNT Ball Valves are crafted with precision and meet a comprehensive array of international standards, including ASME B16.34-2009, ASME B16.10-2000, and API 589-2009. These extraordinary valves excel in numerous industries such as petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations, ensuring optimal performance and reliability.

Key Features:
Innovative, streamlined design allows for quick and effortless disassembly.
Our ball valves are engineered for ease of periodic maintenance with a non-tight fit design, significantly reducing maintenance time and effort.

Advanced sealing technologies ensure the highest levels of safety.
A sophisticated multi-layer combined sealing system for the stem and body offers dual protection through the integration of O-ring and graphite or PTFE seals.
This breakthrough design adheres to stringent TA-Luft/Shell SPE 77/312 standards, ensuring superior performance.

Enduring Durability and Cost-Effectiveness
For metal-sealed ball valves, we employ advanced techniques such as spray welding, spraying, and fusion welding for the ball and seat ring, achieving a hardness range of HRC58-73 and a binding force of 80-40MPa. This results in a robust valve capable of enduring over 100,000 on-off cycles with an excellent leakage class of ANSI VI.

Modular Design for Superior Convenience
The modular inner sealing system design allows seamless interchangeability between soft and metal seats, providing unmatched flexibility and ease of maintenance.

Versatile Connection Options for User-Friendly Experience
Our connection types include flanged (RF, FF, FM, G, RJ), screw-thread, and BW types, all adhering to international standards to ensure maximum user convenience.

Proven Reliability Across Various Applications
SNT Valves are trusted across diverse sectors such as petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations. Our market reputation is built on providing practical solutions tailored to unique service conditions, ensuring dependable performance every time.

Structural Features

 

Our state-of-the-art packing combination is meticulously crafted to meet the stringent emission standards of 100 ppm. This innovative solution not only ensures superior compliance but also reduces stem friction by an impressive 20%, guaranteeing smooth operation and longevity.

1. The robust anti-blowout design is engineered to firmly secure the stem in place, effectively preventing any potential blowout damage. This ensures long-lasting durability and reliable performance.
