Our Advantages

 

SNT Ball Valves boast design specifications that meticulously adhere to a myriad of prestigious 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 across diverse industries such as petroleum, chemical, light industry, pharmacy, paper-making, metallurgy, and power stations, ensuring versatility and reliability.

They possess distinguished characteristics as outlined below,
Ingeniously simple structure facilitates quick disassembly, enhancing operational efficiency.
With a focus on periodic maintenance, our ball valves are engineered for user-friendly upkeep. The non-tight fit design significantly reduces servicing time, offering unparalleled ease during maintenance.

Cutting-edge sealing technology ensures unmatched security.
The innovative multi-layer combined sealing of the stem and body provides robust double sealing through the strategic combination of O-ring and graphite or PTFE, offering enhanced protection.
This sophisticated design complies with TA-Luft and Shell SPE 77/312 standards, ensuring top-tier performance.

Extended service life translates to remarkable cost-effectiveness.
For our metal-sealed ball valves, we employ advanced processing techniques such as spray welding, spraying, and fusion welding on the ball and seat ring. This ensures a hardness range of HRC58-73 and a binding force of 80-40MPa. Impressively, the on-off cycles exceed 100,000 times while maintaining a leakage class of ANSI VI, underscoring our commitment to durability.

Modular design ensures unparalleled convenience.
The inner sealing's modular design allows for seamless interchangeability between soft and metal seats, guaranteeing flexibility and precision.

Diverse connection types provide exceptional convenience.
Featuring a variety of connection types, including flanged (RF, FF, FM, G, RJ), screw-thread, and BW type, our valves adhere to international standards, ensuring ease of use and reliability for any application.

Extensive application experience assures unwavering reliability.
SNT Valves are trusted across industries such as petroleum, chemical, light industry, pharmacy, paper-making, metallurgy, and power stations. Our esteemed reputation in the market is a testament to our ability to provide reliable and tailored solutions based on specific service conditions.

Structural Features

 

Our innovative packing combination is engineered meticulously to meet stringent emission requirements of 100 ppm. This superior design simultaneously reduces friction on the stem by an impressive 20%, enhancing the overall operational efficiency.

1. The robust anti-blowout design effectively prevents the stem from being forcibly ejected, thereby safeguarding the entire system from potential damage.

2. Featuring a sophisticated wave spring and dual-scraper seat ring structure, this design diligently cleans the ball surface, ensuring a pristine and reliable sealing mechanism.

3. An advanced dual-sealing system is implemented to ensure optimal leakage prevention. This design strategically prevents the flow from coming into contact with the spring, thereby maintaining the integrity of the seal.

4. The stability and reliability of our soft seat's sealing performance is unmatched, providing consistent and dependable service under varying conditions.

5. Equipped with an efficient draining and sweeping feature, the valve is engineered to remain free from obstructions, thereby preventing jamming and ensuring seamless operation.

6. Our product complies rigorously with API 607 standards, offering unparalleled fire-proof and anti-static functionalities, ensuring safety and reliability in high-risk environments.
