Product Description

 

Discover the superior engineering of our High Performance Spherical Valve, tailored for diverse, demanding service applications where zero leakage is non-negotiable. This series triumphs in high-temperature and high-pressure environments, ensuring reliability and peace of mind.
Every component of our valve, including the ball and seat, is fortified with robust chrome carbide or tungsten carbide coatings. These materials are renowned for their exceptional resistance to erosion and abrasion, offering you unparalleled durability and longevity.
At SNT, we employ a state-of-the-art HVOF coating system. Our precision mate-lapping technique guarantees 100% sealing performance. With live loading ensuring zero emissions, your system remains secure and efficient. The innovative design ensures the ball stays engaged with the seat, effectively removing contaminants. This self-cleaning capability protects against interference and damage, making our valve an ideal choice for both slurry and abrasive service applications.

 

 

 

 

 

Our Advantages

 

SNT Ball Valves are engineered to meet an array of international standards, including ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009, among others. This exceptional series of products finds extensive application in the petroleum, chemical, light industry, pharmaceutical, paper-making, metallurgy, and power station sectors, reflecting their versatility and reliability.

They possess the following remarkable characteristics:
The straightforward structure allows for swift disassembly.
Our ball valves are designed for periodic maintenance, ensuring ease of service with a non-tight fit design, significantly reducing servicing time and enhancing efficiency.

An advanced sealing mechanism ensures unparalleled security.
The innovative multi-layer combined sealing of the stem and body offers dual protection through an O-ring combined with graphite or PTFE, delivering robust sealing performance.
This design complies with TA-Luft and Shell SPE 77/312 standards, guaranteeing superior performance.

Extended service life translates into cost efficiency.
For metal-sealed ball valves, advanced processing techniques such as spray welding, spraying, and fusion welding are employed on the ball and seat ring to achieve hardness levels of HRC58-73 and binding forces of 80-40MPa. These features ensure over 100,000 on-off cycles with leakage classes reaching ANSI VI, epitomizing durability and precision.

A modular design enhances convenience and adaptability.
The modular inner sealing design allows for interchangeability between soft and metal seats, ensuring flexibility and adaptability to various requirements.

Multiple connection types ensure seamless usability.
With connection types including flanged (RF, FF, FM, G, RJ), screw-thread, and BW types, our valves adhere to international standards, offering unmatched convenience and ease of use.

Extensive application experience ensures reliability.
SNT Valves have garnered widespread usage in petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power station sectors. With a strong market reputation, we deliver optimal solutions tailored to specific service conditions, underscoring our commitment to excellence.

Structural Features
