Product Description

 

Discover a new era in valve technology with our series of Zero-Leakage ball valves, meticulously engineered for a wide range of demanding service applications. Whether facing extreme temperatures or high-pressure environments, these valves guarantee outstanding performance and reliability.
Featuring a robust construction, the ball and seat of these valves are fortified with either chrome carbide or tungsten carbide coatings. This advanced hard coating technology endows the valves with exceptional resistance to erosion and abrasion, ensuring long-lasting durability even in the harshest conditions.
SNT Machinery employs a state-of-the-art HVOF coating system, complemented by our proprietary mate-lapping technique, to achieve unparalleled sealing integrity. Our innovative live-loading mechanism not only ensures zero emissions but also maintains a perfect seal. The ball remains firmly seated, effectively wiping away contaminants and executing a self-cleaning action that safeguards against potential damage. This makes our valves exceptionally well-suited for both slurry and abrasive service applications, delivering reliable performance and protection where it counts most.

 

 

 

 

 

Our Advantages

 

SNT Ball Valves adhere to comprehensive international standards such as ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009, among others. These high-performing valves are extensively applied across various industries including petroleum, chemical, light industry, pharmaceutical, paper-making, metallurgy, and power stations, showcasing their versatile utility.

They boast the following features:
A straightforward design allows for quick and easy disassembly, enhancing operational efficiency.
Our ball valves, designed for periodic maintenance, feature a non-tight fit design that simplifies upkeep and significantly reduces service time.

State-of-the-art sealing technology ensures utmost security.
The multi-layer sealing system, comprising a combination of O-ring and either graphite or PTFE, provides dual sealing for the stem and body, enhancing durability.
This innovative design complies with TA-Luft/Shell SPE 77/312 standards, guaranteeing performance excellence.

Extended service life delivers exceptional cost-effectiveness.
For metal-sealed ball valves, cutting-edge processes like spray welding, spraying, and fusion welding ensure the ball and seat ring achieve a hardness of HRC58-73 and a binding force of 80-40MPa. With over 100,000 on-off cycles, they meet the stringent ANSI VI leakage class.

Modular design provides unparalleled flexibility.
The modular inner sealing design enables interchangeability between soft and metal seats, enhancing adaptability.

Diverse connection types for user-friendly operation.
Offering multiple connection types including flanged (RF, FF, FM, G, RJ), screw-threaded, and BW types, these valves meet international standards for convenient and adaptable use.

Extensive industry experience underscores reliability.
With widespread use in sectors such as petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations, SNT Valve has earned a stellar market reputation. We provide optimal solutions tailored to service conditions, ensuring reliability and satisfaction.

Structural Features

 

The innovative packing combination is engineered to meet stringent emissions requirements, achieving a remarkable 100 ppm while simultaneously reducing friction on the stem by an impressive 20%.

1. Our meticulously crafted anti-blow out design is a guardian of safety, ensuring that the stem remains secure and protected from any potential blowout risks, thus preventing damage.

2. The cutting-edge seat ring structure, featuring a wave spring and dual-scraper mechanism, is adept at maintaining a pristine ball surface, ensuring a consistently reliable seal.

3. Our advanced dual-sealing system is a hallmark of excellence, ensuring the highest leakage class by expertly preventing flow from contacting the spring, thereby guaranteeing optimal performance.

4. Experience unmatched stability and reliability with the sealing performance of our soft seat, designed to perform impeccably under various conditions.

5. The thoughtfully designed draining and sweeping features prevent any potential jamming, ensuring continuous operation by effectively cleaning the valve.

6. Built in compliance with API 607 standards, our valve embodies both fire-proof and anti-static capabilities, offering peace of mind and robust protection in demanding environments.
