Product Description

 

Introducing a groundbreaking series of Zero-Leakage ball valves meticulously designed to excel in a multitude of service applications. These high-performance valves are engineered to withstand extreme high temperatures and pressures, offering exceptional reliability and durability.
Each valve features a ball and seat that are robustly hard-coated with premium chrome carbide or tungsten carbide. This advanced coating technology ensures unparalleled resistance to erosion and abrasion, providing long-lasting performance in the most demanding environments.
At SNT, we employ a cutting-edge HVOF coating system, applying our proprietary mate-lapping technique to guarantee a flawless 100% seal. Our innovative live loading technology further ensures zero emissions, as the ball consistently remains in contact with the seat, effortlessly removing contaminants. This ingenious self-cleaning mechanism protects the valve from interference and damage caused by impurities, making it an ideal choice for slurry and abrasive service applications.

 

 

 

 

 

Our Advantages

 

SNT Ball Valves are meticulously designed to adhere to a variety of prestigious international standards, such as ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009. These versatile products are essential across diverse industries, including petroleum, chemical processing, light industry, pharmaceuticals, paper manufacturing, metallurgy, and power generation.

Outstanding Features of Our Ball Valves
The straightforward design allows for effortless disassembly, ensuring quick and efficient maintenance.
The regular maintenance schedule for all valves ensures our ball valves provide unparalleled ease of servicing. The non-tight fit design significantly reduces servicing time, making maintenance a breeze.

Cutting-Edge Sealing for Unmatched Security
Our innovative multi-layer sealing technology between stem and body combines the strength of O-rings with graphite or PTFE to provide robust double sealing, delivering exceptional security.
This remarkable design is fully compliant with TA-Luft/Shell SPE 77/312 standards, ensuring top-tier performance.

Extended Service Life for Optimal Cost-Effectiveness
Our metal-sealed ball valves employ advanced processing techniques like spray welding and fusion welding for the ball and seat ring. This ensures an impressive hardness of HRC58-73 and a binding force of 80-40MPa. Remarkably, they can withstand over 100,000 on-off cycles with an ANSI VI leakage class.

Convenience Through Modular Design
The intuitive modular design of the inner sealing allows for seamless interchangeability between soft and metal seats, providing unmatched convenience.

Diverse Connection Types for User-Friendly Operations
Our versatile connection options include internationally recognized types like flanged (RF, FF, FM, G, RJ), screw-thread, and BW types, ensuring easy and flexible usage.

Trusted Reliability Through Extensive Application Experience
Widely adopted across industries such as petroleum, chemicals, light industry, pharmaceuticals, paper-making, metallurgy, and power stations, SNT Valves are celebrated for their reliability. Our esteemed reputation is built on providing tailored solutions that align perfectly with service conditions.

Structural Features

 

This innovative product boasts a special packing combination that not only achieves the demanding emission standard of 100 ppm but also remarkably cuts the friction against the stem by a significant 20%. This translates into smoother operation and longer-lasting performance.

1. Ingeniously designed with an anti-blowout feature, this valve prevents the stem from being expelled, thereby effectively averting potential damage and ensuring operational safety.

2. The advanced seat ring design, incorporating a wave spring and dual-scraper, excels at cleaning the ball surface and maintaining optimal sealing, promoting a pristine and efficient flow path.

3. The dual-sealing mechanism is a hallmark of reliability, ensuring that the leakage class remains uncompromised by preventing the flow from contacting the spring, thereby safeguarding the valve's integrity.

4. The soft seat's sealing performance stands out for its stability and reliability, providing a steadfast and unwavering seal that you can rely on.

5. Our design features a draining and sweeping mechanism, skillfully engineered to prevent the valve from jamming. This feature ensures the valve remains clean, enhancing durability and functionality.

6. Meeting the rigorous API 607 standards, this state-of-the-art valve is equipped with fire-proof and anti-static functionalities, ensuring top-tier safety and performance in demanding conditions.
