Product Description

This exceptional series proudly showcases Zero-Leakage ball valves, masterfully engineered for a range of demanding service applications requiring high temperature and/or high pressure. Experience unrivaled performance and impeccable sealing solutions tailored to your operational needs.
Our ball and seat are meticulously fortified with a robust hard coating of either chrome carbide or tungsten carbide. This specialized treatment dramatically enhances their resistance to erosion and abrasion, ensuring long-lasting durability and reliability in the most challenging environments.
At SNT, we employ an advanced HVOF coating system, with components meticulously mate-lapped using our proprietary techniques to guarantee 100% sealing efficiency. Our innovative live loading mechanism further ensures zero emissions. The design features a self-cleaning action where the ball never departs from the seat, effectively wiping away contaminants. This prevents interference and potential damage, making these valves exceptionally suitable for slurry and abrasive service applications.

 

Our Advantages

SNT Ball Valves are meticulously crafted to align with stringent international standards such as ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009, making them an ideal choice for a diverse range of industries including petroleum, chemical, light industries, pharmaceutical, paper-making, metallurgy, and power stations.

Our Valves Boast the Following Features:
Streamlined Design for Effortless Disassembly
With routine maintenance in mind, our ball valves are engineered for simplicity, allowing easy upkeep and minimal downtime due to their non-tight fit design.

State-of-the-Art Sealing for Enhanced Safety
Our advanced multi-layer sealing system for the stem and body provides dual protection, utilizing the combination of O-rings with graphite or PTFE to ensure optimal security.
This innovative design conforms to TA-Luft and Shell SPE 77/312 standards, ensuring compliance and reliability.

Extended Longevity for Cost Efficiency
Our metal sealed ball valves employ cutting-edge techniques such as spray welding and fusion welding for the ball and seat ring, achieving hardness levels of HRC58-73 and a binding force of 80-40MPa. They boast an impressive durability with over 100,000 on-off cycles and meet ANSI VI leakage class standards.
 

Modular Construction for Unmatched Flexibility
The modular inner sealing design allows for seamless interchangeability between soft and metal seats, offering adaptability and convenience.

Versatile Connection Options for User Satisfaction
Our valves feature a variety of connection types including flanged (RF, FF, FM, G, RJ), screw-thread, and BW types, all conforming to international norms for easy and reliable use.

Proven Expertise Ensures Dependability
SNT Valves have earned widespread acclaim in industries like petroleum, chemical processing, light industry, pharmaceuticals, paper manufacturing, metallurgy, and power stations. Our esteemed reputation is built on delivering reliable and tailored solutions based on specific service conditions.

 

Structural Features

Our innovative special packing combination is designed to exceed expectations by fulfilling the stringent smission requirement of 100 ppm. It also ingeniously reduces stem friction by 20%, ensuring superior efficiency and durability.

1. With a cutting-edge anti-blowout design, our product ensures that the stem remains securely in place, effectively preventing any potential damage caused by blowouts.

2. Featuring an advanced seat ring structure with a wave spring and dual-scraper, these components collaboratively maintain a pristine ball surface, ensuring optimal sealing performance.

3. The dual-sealing innovation guarantees exceptional leakage prevention. By ingeniously directing the flow away from the spring, it upholds a top-tier leakage class.

4. Our soft seat sealing performance is engineered for stability and reliability, offering unmatched assurance and peace of mind.

5. With a meticulously designed draining and sweeping mechanism, the valve is adept at preventing jams, maintaining clear pathways through effective cleaning.

6. Adhering to the rigorous API 607 standards, our product is equipped with fire-proof and anti-static functionalities, providing you with enhanced safety and peace of mind.
