Product Description

Introducing our top-of-the-line series of Zero-Leakage ball valves, expertly designed for a multitude of demanding service applications, including those involving extreme temperatures and intense pressures. Experience unparalleled reliability and performance.
Our advanced ball valves feature a ball and seat robustly hard-coated with either chrome carbide or tungsten carbide. This specialized treatment offers exceptional resistance to erosion and abrasion, ensuring long-lasting durability even in the most challenging conditions.
SNT proudly utilizes the cutting-edge HVOF coating system. Our proprietary mate-lapping technique guarantees absolute sealing, while live loading further assures zero emissions. The ingenious design ensures the ball never leaves the seat, effectively wiping away contaminants. This self-cleaning action not only prevents interference but also protects against damage from contaminants, making it an ideal choice for both slurry and abrasive services.

 

Our Advantages

SNT Ball Valves are ingeniously crafted to adhere to an array of prestigious international standards, such as ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009. These versatile products find applications across diverse sectors, including petroleum, chemical industry, light industry, pharmacy, paper-making, metallurgy, and power stations, ensuring unmatched reliability and performance.

They possess the following distinguished features:
The straightforward design allows for swift and hassle-free disassembly.
Through routine maintenance of all valves, our ball valves are engineered with a user-friendly non-tight fit design, significantly minimizing servicing time and effort.

Cutting-edge sealing technology ensures unparalleled safety and security.
The innovative multi-layer combined sealing system of the stem and body offers robust double sealing through an ingenious amalgamation of O-ring with graphite or PTFE, providing exceptional reliability.
This advanced sealing design is compliant with TA-Luft/Shell SPE 77/312 standards, offering peace of mind.

Longevity and cost-effectiveness are achieved through durable design.
Our metal-sealed ball valves utilize state-of-the-art processing for the ball and seat ring, incorporating spray welding, spraying, and fusion welding to achieve an impressive hardness of HRC58-73 and a binding force of 80-40MPa. This ensures over 100,000 on-off cycles and a leakage class of ANSI VI.
 

The modular design provides unparalleled convenience.
The inner sealing's modular design allows for seamless interchangeability between soft and metal seats, ensuring adaptability and reliability in diverse applications.

A variety of connection types ensures user-friendly operation.
Our connection options, including flanged types (RF, FF, FM, G, RJ), screw-thread types, and BW types, are universally compatible, offering effortless integration and usage.

Extensive application experience guarantees unwavering reliability.
SNT Valves have been trusted across industries such as petroleum, chemical, light industry, pharmacy, paper-making, metallurgy, and power stations. We are renowned for our stellar reputation and our ability to provide optimal solutions tailored to specific service conditions, enhancing operational efficiency.

 

Structural Features

Our expertly crafted packing combination is designed to exceed expectations. It achieves a remarkable emission requirement of 100 ppm, while effectively reducing friction by an impressive 20%, ensuring optimal performance and longevity for the stem.

1. Ingeniously engineered with an anti-blowout design, this feature prevents the stem from being ejected, safeguarding against potential damage and ensuring continuous reliability.

2. The seat ring's innovative wave spring and dual-scraper structure meticulously cleans the ball surface, ensuring impeccable sealing and prolonged valve integrity.

3. Our dual-sealing technology is crafted to ensure superior leakage control. By preventing the flow from contacting the spring, it guarantees a high leakage class, enhancing the valve's operational efficiency.

4. Experience unmatched stability and reliability with our soft seat, designed to deliver consistent and trustworthy sealing performance throughout its lifecycle.

5. The advanced design of draining and sweeping functions efficiently prevents valve jamming by maintaining cleanliness, ensuring uninterrupted operation.
