Product Description

 

This series proudly showcases our Zero-Leakage ball valves, meticulously engineered for a myriad of service applications demanding the utmost reliability in high temperature and/or high pressure environments.
The innovative design features a ball and seat that are meticulously hard coated with premium chrome carbide or tungsten carbide, offering unparalleled erosion and abrasion resistance for enduring performance.
At SNT Machinery, we employ an advanced HVOF coating system and our proprietary mate-lapping technique to guarantee impeccable 100% sealing. Our live loading mechanism ensures zero emissions, as the ball consistently maintains contact with the seat, effectively wiping away contaminants. This ingenious self-cleaning action shields against interference and damage, making these valves exceptionally suited for both slurry and abrasive services.

 

 

 

 

 

Our Advantages

 

SNT Ball Valves are meticulously engineered to comply with a broad spectrum of international standards, including ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009, among others. These versatile products are extensively deployed across various industries such as petroleum, chemical manufacturing, light industry, pharmaceuticals, paper-making, metallurgy, and power stations.

Key Features of Our Products Include:
Innovative Simple Structure Ensures Quick and Efficient Disassembly
Thanks to the regular maintenance of all valves, our ball valves are designed for seamless upkeep with a non-tight fit that significantly reduces servicing time.

Advanced Sealing Technology Guarantees Optimal Security
The multi-layered combined sealing system of the stem and body provides dual protection through the integration of an O-ring with graphite or PTFE, enhancing sealing reliability.
This innovative design complies with TA-Luft/Shell SPE 77/312 standards, ensuring superior performance.

Extended Service Life for Greater Cost-Effectiveness
In metal-sealed ball valves, cutting-edge processing techniques such as spray welding, spraying, and fusion welding are employed on ball and seat rings to achieve hardness levels of HRC58-73 and a binding force of 80-40MPa. These features ensure over 100,000 on-off cycles with a leakage class of ANSI VI, maximizing durability and efficiency.

Convenience Through Modular Design
The modular inner sealing design offers the flexibility to interchange between soft and metal seats, ensuring adaptability and ease of maintenance.

Diverse Connection Types for Comfortable and Versatile Usage
Our connection options include flanged types (RF, FF, FM, G, RJ), screw-thread, and BW types, all internationally standardized for user convenience.

Extensive Application Experience Ensures Reliability
SNT Valves have been widely adopted in sectors such as petroleum, chemical manufacturing, light industry, pharmaceuticals, paper-making, metallurgy, and power stations. Our esteemed reputation in the market speaks to our ability to provide sound solutions tailored to specific service conditions.

Structural Features

 

Ingeniously crafted special packing combinations not only fulfill the demanding transmission requirements of up to 100 ppm but also ingeniously reduce friction by a remarkable 20%, ensuring optimal performance and longevity for the stem.

1. Meticulously designed with an anti-blowout feature, preventing the stem from inadvertently ejecting and causing any potential damage, thereby ensuring unparalleled safety and reliability.

2. The innovative structure of the seat ring, equipped with a wave spring and dual-scraper, expertly cleans the ball surface to maintain an impeccable seal, ensuring long-lasting and effective operation.

3. Our advanced dual-sealing mechanism guarantees superior leakage prevention by ensuring that the flow does not come into contact with the spring, providing peace of mind with its steadfast reliability.

4. Experience unmatched stability and dependability with the soft seat's sealing performance, which remains consistently reliable and robust under varied conditions.

5. The innovative draining and sweeping design effectively prevents the valve from becoming jammed, ensuring smooth and continuous operation through thorough cleaning.

6. Fully compliant with API 607 standards, this product boasts essential fire-proof and anti-static functionalities, offering exceptional safety and performance under demanding conditions.
