SNT Ball Valves' design specifications proudly adhere to a comprehensive suite of international standards, including ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009. This exceptional series of products finds its applications across diverse industries such as petroleum, chemical manufacturing, light industry, pharmaceuticals, paper-making, metallurgy, and power generation, ensuring top-tier performance and reliability.

They possess the following outstanding characteristics:
Their simple structure allows for effortless disassembly, providing unparalleled ease and speed when servicing is required.
Designed for ease of maintenance, our ball valves feature a non-tight fit that significantly reduces servicing time, thanks to their periodic maintenance advantage.

Our advanced sealing technology ensures superior security and reliability.
The multi-layer combined sealing between the stem and body delivers double the security through the innovative combination of O-ring and graphite or PTFE seals.
This ingeniously crafted design meets the stringent TA-Luft/Shell SPE 77/312 standards, assuring top-notch performance.

A long service life translates to exceptional cost-effectiveness.
For our metal-sealed ball valves, we employ cutting-edge processing techniques such as spray welding, spraying, and fusion welding. These methods ensure a hardness level of HRC58-73 and a binding force of 80-40MPa. Consequently, they boast over 100,000 on-off cycles while achieving ANSI VI leakage class.
 


Our modular design provides unmatched convenience.
The modular design of the inner sealing system allows for easy interchangeability between soft and metal seats, ensuring flexibility and enhanced serviceability.

Multiple connection types provide seamless and adaptable usage.
With connection types including flanged (RF, FF, FM, G, RJ), screw-thread, and BW type, these options are internationally standardized, offering users worldwide convenience and adaptability.

Our extensive experience guarantees reliability.
SNT Valves are highly regarded in industries such as petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations. We are renowned for delivering reliable solutions tailored to specific service conditions, backed by our solid market reputation.

 

The innovative packing combination is meticulously engineered to not only meet the stringent emission requirements of 100 ppm but also to reduce stem friction significantly by 20%, ensuring smooth and efficient operation.
