Product Description

 

Introducing our exceptional series of Zero-Leakage ball valves, meticulously engineered for versatile service applications, especially under conditions of high temperature and/or high pressure. Experience unparalleled reliability and performance!
Our innovative ball and seat design features a robust hard coating, utilizing either chrome carbide or tungsten carbide. This advanced technology offers superior erosion and abrasion resistance, ensuring enduring strength and durability.
At SNT Machinery, we employ the state-of-the-art HVOF coating system, perfectly complemented by our proprietary mate-lapping technique. This guarantees 100% sealing effectiveness. With the added benefit of live loading, the valve maintains zero emissions. The ingenious design ensures the ball remains seated, effectively wiping away contaminants. This self-cleaning action protects against interference and damage from impurities, making our valve an ideal choice for slurry and abrasive service environments.

 

 

 

 

 

Our Advantages

 

SNT Ball Valves are crafted with precision, adhering to a plethora of international standards such as ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009, among others. This versatile series of products finds their robust applications across a spectrum of industries including petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations.

They boast remarkable features as outlined below,
The simple structure ensures swift and hassle-free disassembly.
Our ball valves are engineered for ease of maintenance, featuring a non-tight fit design that minimizes servicing time, a boon for periodic upkeep.

Cutting-edge sealing technology guarantees exceptional security.
The multi-layered sealing system, combining O-ring and graphite or PTFE, provides superior double sealing for both stem and body.
This innovative design is compliant with TA-Luft/Shell SPE 77/312 standards.

Prolonged service life ensures optimal cost-effectiveness.
For metal sealed ball valves, cutting-edge techniques such as spray welding, spraying, and fusion welding are applied to the ball and seat ring. This ensures a hardness of HRC58-73 and a binding force of 80-40MPa. Additionally, the on-off operations can exceed 100,000 cycles, meeting the ANSI VI leakage class.

Modular design enhances convenience and adaptability.
Our modular inner sealing design allows for seamless interchangeability between soft and metal seats, ensuring unparalleled flexibility.

Diverse connection types provide ultimate comfort and usage flexibility.
The variety of connection types, including flanged (RF, FF, FM, G, RJ), screw-thread, and BW types, are internationally standardized, offering effortless usability.

Extensive application experience guarantees unwavering reliability.
SNT Valves have been extensively deployed in petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations. We enjoy a stellar reputation in the market, providing intelligent solutions tailored to specific service conditions.

Structural Features

 

Our innovative special packing combination not only meets the rigorous emission standard of 100 ppm but also significantly reduces stem friction by 20%, ensuring smoother and more efficient operations.

1. The meticulous anti-blowout design effectively prevents the stem from ejecting, thereby safeguarding the entire system from potential damage.

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

3. Our dual-sealing technology ensures an impeccable leakage class by isolating the flow from the spring, thereby enhancing safety and reliability.

4. The soft seat's sealing performance is designed for superior stability and reliability, offering peace of mind in various operational conditions.

5. The innovative design incorporating draining and sweeping functions effectively prevents valve jamming by facilitating thorough cleaning.

6. Compliant with API 607 standards, this product boasts fire-proof and anti-static properties, making it a robust choice for critical applications.
