Product Description

 

Unveiling an exceptional series of Zero-Leakage Ball Valves that thrive in demanding service applications, this line is engineered to withstand high temperatures and pressures with unwavering performance.
Our ball and seat components boast a robust hard coating, meticulously applied using chrome carbide or tungsten carbide. This advanced coating significantly enhances resistance to erosion and abrasion, ensuring long-lasting durability.
At SNT, we employ a state-of-the-art HVOF coating system complemented by our proprietary mate-lapping technology. This innovation guarantees complete sealing and zero emissions via live loading, maintaining the ball's perfect seating position and effectively sweeping away contaminants. This self-cleaning mechanism not only averts interference but also prevents damage caused by contaminants, making this valve an ideal choice for slurry and abrasive services.

 

 

 

 

 

Our Advantages

 

SNT Ball Valves are meticulously crafted adhering to a broad spectrum of international standards, such as ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009, among others. These valves seamlessly integrate into diverse fields, including petroleum, chemical industry, light industry, pharmaceuticals, paper-making, metallurgy, and power stations.

Key Characteristics of Our Valves:
Innovatively simple structure promotes effortless disassembly, ensuring user convenience.
With routinely scheduled maintenance practices, our ball valves are engineered for easy upkeep. The non-tight fit design notably reduces servicing time, enhancing operational efficiency.

Our cutting-edge sealing technologies ensure unmatched security and reliability.
The multi-layered, combined sealing mechanism of the stem and body provides double-layer protection. This is achieved through the integration of an O-ring with graphite or PTFE for robust sealing.
This innovative design complies with TA-Luft/Shell SPE 77/312 standards, ensuring superior performance.

Extended Service Life for Optimal Cost Efficiency
For our metal-sealed ball valves, we employ advanced techniques like spray welding, spraying, and fusion welding on the ball and seat ring. This ensures a hardness level of HRC58-73 and a binding force of 80-40MPa. Remarkably, the valves can withstand over 100,000 on-off cycles while maintaining leakage class ANSI VI.

Convenience Through Modular Design
Our modular design of internal seals allows for the interchange of soft and metal seats, providing unparalleled flexibility and assurance.

Multiple Connection Formats for User-Friendly Experience
Offering various connection types such as flanged (RF, FF, FM, G, RJ), screw-thread, and BW, our valves align with international standards, delivering seamless and convenient usage.

Reliability Rooted in Extensive Experience
Renowned in industries like petroleum, chemical, light, pharmaceuticals, paper-making, metallurgy, and power stations, SNT Valves stand as a testament to reliability and ingenuity. We craft reasonable solutions tailored to specific service conditions, earning an esteemed market reputation.

Structural Features

 

The innovative packing combination is engineered to meet transmission requirements of up to 100 ppm, while ingeniously reducing friction by a remarkable 20% to the stem. This ensures smooth operation and enhanced durability.

1. The anti-blowout design effectively prevents the stem from being ejected, safeguarding against potential damage and ensuring safety.

2. The seat ring structure, featuring a wave spring and dual-scraper mechanism, meticulously cleans the ball surface, maintaining optimal sealing and performance.

3. Dual-sealing technology is employed to ensure superior leakage protection by preventing the flow from coming into contact with the spring, thereby maintaining the integrity of the sealing system.

4. The soft seat's sealing performance is renowned for its stability and reliability, offering consistent protection and peace of mind.

5. The innovative draining and sweeping design effectively prevents the valve from jamming, ensuring cleanliness and uninterrupted operation.

6. Fully compliant with API 607 standards, this valve offers exceptional fire-proof and anti-static capabilities, providing robust safety features.
