Product Description

 

Discover the pinnacle of innovation with our Floating Ball Valve, meticulously engineered to deliver flawless Zero-Leakage performance across a diverse range of high-temperature and high-pressure service applications.
Our ball and seat are expertly fortified with hard coatings of chrome carbide or tungsten carbide, offering exceptional resistance to erosion and abrasion, ensuring longevity and reliability even in the most demanding environments.
At SNT, we employ the state-of-the-art HVOF coating system, complemented by our proprietary mate-lapping technique, guaranteeing impeccable 100% sealing. The integration of live loading further assures zero emissions. Ingeniously designed, the ball remains in constant contact with the seat, effectively wiping away contaminants to prevent potential interference and damage. This self-cleaning marvel makes our valve the perfect solution for challenging slurry and abrasive service conditions.

These exceptional valves find extensive applications across diverse industries including petroleum, chemical processing, light manufacturing, pharmaceuticals, paper production, metallurgy, and power generation.

Key Features and Benefits,
Ingeniously simple structure enables rapid disassembly.
With routine maintenance being paramount, our ball valves are designed for effortless servicing thanks to their non-tight fit, significantly reducing maintenance time.

Cutting-edge sealing technology ensures unmatched security.
The multi-layered, combined sealing of stem and body provides dual protection via a sophisticated blend of O-ring and graphite or PTFE, ensuring top-tier sealing performance.
This meticulously crafted design adheres to TA-Luft/Shell SPE 77/312 standards.

Extended service life delivers exceptional cost efficiency.
For our metal-sealed ball valves, advanced techniques such as spray welding, spraying, and fusion welding are employed to achieve hardness levels of HRC58-73 and a binding force of 80-40MPa. Impressively, the valves boast an operational lifespan exceeding 100,000 cycles with an ANSI VI leakage class.

The modular design enhances operational convenience.
This innovative modular design allows the inner sealing components to be easily interchanged between soft and metal seats, ensuring adaptable performance.

Diverse connection options ensure user-friendly operation.
The versatile connection types include flanged (RF, FF, FM, G, RJ), screw-thread, and BW types, all of which are internationally standardized for seamless integration and user convenience.

Extensive application experience ensures reliability.
SNT Valves are trusted and extensively utilized in sectors such as petroleum, chemical processing, light industry, pharmaceuticals, paper manufacturing, metallurgy, and power generation. We hold a sterling reputation in the market, providing effective solutions tailored to specific service conditions.

Structural Features

 

Our specially engineered packing combination proficiently meets the stringent smission requirement of 100 ppm. Simultaneously, it ingeniously reduces stem friction by an impressive 20%, ensuring optimal performance.

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

2. The seat ring structure, featuring a wave spring and dual-scraper, provides an exceptional cleaning mechanism for the ball surface, maintaining impeccable sealing integrity.

3. Our dual-sealing technology ensures an unparalleled leakage class by ingeniously preventing the flow from contacting the spring, thereby enhancing reliability.

4. The soft seat's sealing performance is meticulously engineered for enhanced stability and reliability, offering consistent and dependable operation.

5. The thoughtfully designed draining and sweeping features actively prevent valve jamming by effectively cleaning the system, ensuring smooth functionality.
