Product Description

 

Introducing the premium Spherical Valve with A351CF8 Body, this exceptional series of Zero-Leakage ball valves is engineered for excellence in a variety of demanding service applications. Whether facing high temperature or pressure challenges, these valves deliver unparalleled reliability and performance.
Featuring a robust design, the ball and seat components are fortified with high-performance hard coatings of chrome carbide or tungsten carbide, offering superior resistance to erosion and abrasion. This ensures durability and long-lasting functionality, even in the harshest conditions.
At SNT, we employ the advanced HVOF coating system, coupled with our proprietary mate-lapping techniques, to guarantee a flawless 100% seal. Our innovative live loading mechanism further ensures zero emissions, enhancing environmental protection. The unique design allows the ball to maintain constant contact with the seat, effectively wiping away contaminants. This self-cleaning feature not only safeguards against interference and damage but also makes the valve ideally suited for handling slurry and abrasive services with ease and efficiency.

 

 

 

 

 

Our Advantages

 

SNT Ball Valves, a hallmark of precision and quality, adhere to a comprehensive array of prestigious international standards including ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009. These versatile products are indispensably integrated into a multitude of industries such as petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations.

Distinguished Features Include:
A straightforward design that enables swift disassembly.
Our ball valves are engineered for easy maintenance, thanks to a non-tight fit design that significantly cuts down on servicing time, allowing for regular upkeep to be performed with ease.

Innovative sealing technology ensures unparalleled security.
The multi-layer combined sealing of the stem and body delivers dual protection through an ingenious blend of O-ring and graphite or PTFE, ensuring robust sealing capabilities.
This state-of-the-art design is compliant with TA-Luft/Shell SPE 77/312 standards, guaranteeing superior performance.

Impressive Longevity Ensures Cost Efficiency
Employing cutting-edge processing techniques such as spray welding, spraying, and fusion welding for metal-sealed ball valves, we achieve a remarkable hardness of HRC58-73 and a binding force of 80-40MPa. These features ensure more than 100,000 on-off cycles, meeting the ANSI VI leakage class.

Modular Design for Enhanced Versatility
The modular inner sealing design offers the flexibility of interchangeability between soft and metal seats, ensuring adaptability to diverse requirements.

Diverse Connection Options for User-Friendly Application
Available in various connection types such as flanged (RF, FF, FM, G, RJ), screw-thread, and BW type, our valves meet international norms and provide unmatched convenience in application.

Expertise in Application Assures Reliability
SNT Valve has a proven track record across industries like petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations. We boast a stellar market reputation, delivering prudent solutions tailored to specific service conditions.

Structural Features

 

The innovative special packing combination is meticulously engineered to meet the stringent smission requirement of 100 ppm. Additionally, it ingeniously reduces friction by an impressive 20% to the stem.

1. The anti-blowout design is a critical safety feature that effectively prevents the stem from being ejected, thereby averting potential damage.

2. The cutting-edge structure of the seat ring integrates a wave spring and dual-scraper, which work harmoniously to meticulously clean the ball surface, ensuring a secure and durable seal.

3. Dual-sealing technology provides robust assurance of achieving a high leakage class by ingeniously preventing the flow from contacting the spring.

4. The sealing performance of the soft seat is engineered for supreme stability and unmatched reliability.

5. The innovative design incorporates draining and sweeping mechanisms to effectively prevent the valve from jamming, ensuring continuous and efficient cleaning.

6. This product strictly adheres to API 607 standards, boasting advanced fire-proof and anti-static capabilities for enhanced safety and performance.
