Product Description

Discover the exceptional performance and reliability of our Zero-Leakage Ball Valves, expertly engineered to meet the demands of diverse service applications. Designed to withstand high temperatures and high pressure, these valves ensure seamless operation in the most challenging environments.
Crafted with precision, the ball and seat of our valves undergo a hard coating process with either chrome carbide or tungsten carbide. This enhances their durability, offering exceptional erosion and abrasion resistance, ensuring long-lasting performance.
At SNT Machinery, we leverage advanced HVOF coating technology and employ our proprietary mate-lapping technique to guarantee a 100% sealing performance. Our live loading feature further ensures zero emissions, while the innovative design keeps the ball continuously seated, effectively wiping away contaminants. This self-cleaning mechanism not only prevents interference but also protects against damage from contaminants, making these valves ideally suited for slurry and abrasive services.

 

Our Advantages

SNT Ball Valves are meticulously crafted to adhere to an extensive range of international standards, including ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009. Renowned for their versatility, these valves find widespread application across various industries such as petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations, ensuring optimal performance.

They are distinguished by the following exceptional features:
The straightforward design enables swift disassembly for maintenance ease.
Thanks to regular valve maintenance, our ball valves are engineered with a non-tight fit design that simplifies servicing and reduces downtime.

Innovative sealing technology ensures enhanced safety and reliability.
A sophisticated multi-layer combined sealing system for both stem and body offers dual sealing capabilities through an ingenious blend of O-ring and graphite or PTFE.
This advanced sealing solution meets stringent TA-Luft/Shell SPE 77/312 standards.

Extended service life translates to greater cost-effectiveness for users.
Our metal-sealed ball valves employ cutting-edge processing techniques like spray welding, spraying, and fusion welding to achieve remarkable hardness levels of HRC58-73 and binding forces between 80-40MPa. This ensures the valves exceed 100,000 on-off cycles, with leakage conforming to ANSI VI standards.
 

A Modular Design Delivers Exceptional Flexibility
The modular system of inner sealing offers flexibility, allowing for the interchangeability between soft and metal seats, ensuring adaptability to various requirements.

Diverse Connection Types Enhance User Experience
Our valves accommodate multiple connection styles, including flanged (RF, FF, FM, G, RJ), screw-thread, and BW types. These globally recognized standards provide users with utmost convenience and ease of installation.

Extensive Application Experience Ensures Trustworthy Performance
SNT Valves have earned a stellar reputation, being extensively utilized across petroleum, chemical, light industry, pharmaceutical, paper-making, metallurgy, and power station sectors. We are committed to delivering dependable solutions tailored to the specific service conditions, cementing our place as a trusted industry leader.

 

Structural Features

Our innovative special packing combination is engineered to meet stringent smission requirements of 100 ppm. Moreover, it's designed to reduce friction by an impressive 20% to the stem, ensuring smoother and more efficient operations.

1. Featuring an advanced anti-blowout design, this mechanism ensures the stem remains securely in place, preventing any potential damage that could occur from blowout incidents.

2. The seat ring structure, enhanced with a wave spring and dual-scraper, is expertly crafted to maintain optimal sealing by effectively cleaning the ball surface, ensuring consistent performance and reliability.

3. Our innovative dual-sealing technology ensures superior leakage prevention by strategically preventing flow contact with the spring, thus maintaining an exceptional leakage class.

4. Experience superior stability and reliability with our soft seat sealing performance, crafted to deliver consistent and dependable results.

5. Our thoughtfully designed draining and sweeping functions are integral in preventing valve jamming, ensuring seamless operations through effective cleaning.

6. Adhering to the stringent API 607 standards, our products are equipped with robust fire-proof and anti-static functionalities, offering unparalleled safety and performance.
