Product Description

Introducing an unparalleled series of Zero-Leakage Ball Valves, adeptly engineered for high-temperature and high-pressure environments, perfect for flammable gas and liquid service applications.
Our meticulously designed ball and seat components feature a robust hard coating of either chrome carbide or tungsten carbide, providing exceptional resistance to erosion and abrasion.
SNT proudly employs an advanced HVOF coating system to ensure precision and durability. Our proprietary mate-lapped technique guarantees a flawless 100% seal. Additionally, the live loading feature ensures absolute zero emissions, with the ball consistently seated to effectively wipe away contaminants. This ingenious self-cleaning function prevents potential interference and damage from impurities, making these valves ideal for handling slurry and abrasive services with ease.

 

Our Advantages

SNT Ball Valves are meticulously crafted to adhere to a broad spectrum of international standards, including ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009. This exceptional product line finds its versatile application across numerous industries such as petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power generation.

They possess the following distinctive features:
A straightforward design facilitates swift disassembly.
Thanks to the regular maintenance of all valves, our ball valves are designed for easy maintenance, featuring a non-tight fit design that substantially reduces servicing time.

State-of-the-art sealing ensures uncompromised security.
A multi-layered sealing system between the stem and body provides enhanced double sealing through the integration of O-ring and graphite or PTFE, ensuring superior protection.
This innovative design complies with TA-Luft/Shell SPE 77/312 standards, affirming its robust performance.

Exceptional longevity delivers remarkable cost-effectiveness.
For metal-sealed ball valves, we employ advanced techniques such as spray welding, spraying, and fusion welding on the ball and seat ring, ensuring a hardness level of HRC58-73 and a binding force of 80-40MPa. These valves can endure over 100,000 on-off cycles and meet ANSI VI leakage standards.
 

Modular design brings extraordinary convenience.
The modular inner sealing design allows for the interchangeability between soft and metal seats, guaranteeing flexibility and reliability.

Diverse connection options ensure user-friendly experience.
The connection types encompass widely recognized standards like flanged type (RF, FF, FM, G, RJ), screw-thread type, and BW type, providing convenient and adaptable usage.

Vast application expertise ensures unparalleled reliability.
SNT Valves are extensively utilized in sectors such as petroleum, chemical industry, light industry, pharmaceuticals, paper-making, metallurgy, and power stations. Renowned for our strong market reputation, we offer tailored solutions that align with various service conditions to meet your needs.

 

Structural Features

Our innovative packing combination is engineered to exceed industrial standards, achieving an emission level of 100 ppm while enhancing operational efficiency by reducing friction on the stem by a remarkable 20%.

1. Expertly designed with an anti-blow out feature, our valves are safeguarded against stem blowout, ensuring utmost protection against potential damage.

2. The advanced seat ring structure, featuring a wave spring and dual-scraper system, effectively cleans the ball surface, ensuring continuous and uncompromised sealing integrity.

3. Dual-sealing technology assures superior leakage prevention by isolating the spring from the flow, maintaining the highest standards of leakage class.

4. Our soft seat design promises enhanced stability and reliability in sealing performance, essential for critical operations.

5. Ingeniously crafted with a draining and sweeping mechanism, our valves are designed to prevent jamming by effectively cleaning any potential obstructions.

6. Our valves are in full compliance with API 607 standards, offering robust fire-proof and anti-static capabilities, ensuring safety and reliability under rigorous conditions.
