SNT Ball Valves are meticulously crafted to align with a multitude of international standards, including ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009. This exclusive range of valves is significantly utilized across various sectors such as petrochemical, chemical industry, light industry, pharmaceuticals, paper production, metallurgy, and power stations, showcasing their adaptability and extensive applications.

Key Features and Characteristics:
A streamlined structure facilitates quick and easy disassembly, enhancing user convenience.
Our ball valves are engineered for effortless maintenance, thanks to their non-tight fit design. This ensures periodic maintenance is a breeze, significantly reducing service time and enhancing operational efficiency.

Cutting-edge sealing technology ensures robust security and reliability.
The innovative multi-layer combined sealing system between the stem and body delivers double protection, utilizing a combination of O-ring with graphite or PTFE, ensuring top-notch sealing performance.
This advanced design complies with stringent TA-Luft/Shell SPE 77/312 standards, ensuring superior performance.

Extended service life leads to remarkable cost efficiency.
For our metal-sealed ball valves, sophisticated techniques such as spray welding, spraying, and fusion welding are employed for processing the ball and seat ring. This guarantees exceptional hardness ranging from HRC58 to HRC73 and a binding force of 80-40MPa, with more than 100,000 on-off cycles, meeting ANSI VI leak standards.
 


Modular design enhances operational flexibility.
The modular design of the internal sealing system allows for the interchangeability between soft and metal seats, promising adaptable functionality and service versatility.

Diverse connection types ensure easy and versatile installation.
Offering a variety of connection types such as flanged (RF, FF, FM, G, RJ), screw-thread, and BW type, all conforming to international standards, these connections provide seamless and convenient usability.

Vast application experience fosters unmatched reliability.
SNT Valves have proven their reliability and efficiency across numerous industries, including petroleum, chemical industries, light industries, pharmaceuticals, paper manufacturing, metallurgy, and power stations. We are renowned for our market reputation, providing ingenious solutions tailored to specific service conditions.

 

Our unique special packing combination excels in meeting the demanding transmission requirement of 100 ppm. What's more, it ingeniously reduces friction by 20%, ensuring a seamless and efficient stem performance.
