Product Description

 

This exceptional series features Zero-Leakage ball valves, ideal for a multitude of service applications enduring high temperatures and/or high pressures. Witness unparalleled reliability and efficiency.
Crafted with precision, the ball and seat are fortified with a hard coating of chrome carbide or tungsten carbide. This ensures superior resistance to erosion and abrasion, making it the epitome of durability.
SNT employs a state-of-the-art HVOF coating system, meticulously mate-lapped using proprietary techniques to guarantee 100% sealing. The innovative live loading mechanism further ensures zero emissions. Ingeniously designed, the ball remains in constant contact with the seat, effectively wiping away contaminants. This self-cleaning feature prevents any interference or damage from debris, making it perfectly suited for slurry and abrasive service applications.

 

 

 

 

 

Our Advantages

 

SNT Ball Valves are meticulously crafted to align with a myriad of prestigious international standards, including ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009. These top-tier products find widespread application across diverse industries such as petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations, ensuring reliability and excellence wherever they are employed.

They feature outstanding characteristics as outlined below:
Ingenious design ensures effortless assembly and disassembly.
With regular maintenance as a cornerstone, our ball valves are engineered for easy maintenance, thanks to a non-tight fit design that significantly reduces servicing time, enhancing operational efficiency.

Superior sealing technology ensures unparalleled safety and leak prevention.
A sophisticated multi-layer sealing system integrates the stem and body, providing a dual sealing mechanism through a blend of O-ring and graphite or PTFE, ensuring maximum protection.
This innovative design complies with esteemed TA-Luft and Shell SPE 77/312 standards.

Extended durability ensures exceptional cost efficiency over time.
For metal-sealed ball valves, cutting-edge processes such as spray welding, spraying, and fusion welding are employed on the ball and seat ring. This ensures hardness levels of HRC58-73 and a binding force of 80-40MPa, enabling over 100,000 on-off cycles with ANSI VI leakage class, guaranteeing robust performance and longevity.

Modular design enhances operational flexibility and convenience.
The innovative modular design of the inner sealing allows for seamless interchangeability between soft and metal seats, offering unparalleled adaptability.

Diverse connection options ensure ease of use and compatibility.
The valves offer globally recognized connection types, including flanged types (RF, FF, FM, G, RJ), screw-thread, and BW types, ensuring convenient and flexible application across various systems.

Extensive industry experience guarantees reliability and trust.
SNT Valves are extensively utilized in fields such as petroleum, chemical industry, light industry, pharmaceuticals, paper-making, metallurgy, and power stations. We have built a stellar market reputation, offering well-founded solutions tailored to specific service conditions, thereby ensuring client satisfaction.

Structural Features

 

The innovative special packing combination is engineered to meet stringent smission requirements of just 100 ppm, while simultaneously reducing friction against the stem by an impressive 20%. This ensures optimal performance and longevity.

1. The advanced anti-blowout design is meticulously crafted to safeguard against the stem being propelled out, thereby preventing potential damage and enhancing safety.

2. Featuring a state-of-the-art seat ring structure with wave spring and dual-scraper technology, this design effectively cleans the ball surface, ensuring consistent sealing integrity and performance.

3. Our dual-sealing technology is engineered to guarantee exceptional leakage protection by ensuring that the flow never contacts the spring, maintaining optimal functionality.

4. Experience the unparalleled stability and reliability of our soft seat sealing performance, meticulously designed for superior and consistent results.

5. The intelligent design of draining and sweeping mechanisms effectively prevents valve jamming by thoroughly cleaning, ensuring smooth operation.

6. Engineered to comply with API 607 standards, our products boast fire-proof and anti-static capabilities, ensuring robust safety and reliability.
