Product Description

Introducing our exceptional series of advanced control valves, engineered to deliver Zero-Leakage performance across a multitude of demanding service applications. These ball valves are expertly designed to withstand the rigors of high temperature and high-pressure environments, ensuring reliability and efficiency in critical conditions.
Each valve features a ball and seat that are meticulously hard-coated with either chrome carbide or tungsten carbide. This specialized coating offers superior resistance to erosion and abrasion, extending the lifespan of the valve even in the most challenging operational settings.
At SNT Machinery, we utilize an advanced HVOF (High-Velocity Oxygen Fuel) coating system. Our proprietary mate-lapping technique guarantees a perfect seal, achieving 100% leak-proof performance. The innovative live loading mechanism further ensures zero emissions, maintaining environmental compliance. The ball remains seated, effectively wiping away contaminants, a vital self-cleaning function that safeguards against interference and damage. Designed for excellence, these valves are ideally suited for use in slurry and abrasive service applications, providing unmatched durability and performance.

 

Our Advantages

SNT Ball Valves are expertly crafted to adhere to a plethora of international standards such as ASME B16.34-2009, ASME B16.10-2000, and API 589-2009. These exceptional products are extensively utilized across industries including petroleum, chemical, light industry, pharmacy, paper-making, metallurgy, and power stations, providing unparalleled reliability and performance.

Our Valves Exhibit the Following Features:
Effortless design allows for quick disassembly, ensuring minimal downtime during servicing.
Thanks to the periodic maintenance strategy, our ball valves feature a user-friendly non-tight fit design that significantly reduces servicing time, enhancing ease of maintenance.

Enhanced sealing technology ensures utmost security and reliability.
The multi-layered, combined sealing system between the stem and body provides superior double sealing through the ingenious use of O-ring and graphite or PTFE materials.
This innovative design is in full compliance with the stringent TA-Luft and Shell SPE 77/312 standards, ensuring environmental safety and operational excellence.

Extended service life translates to outstanding cost-effectiveness.
Our metal-sealed ball valves employ advanced techniques such as spray welding and fusion welding on the ball and seat ring. With hardness ratings of HRC58-73 and a binding force of 80-40MPa, these valves achieve over 100,000 on-off cycles while adhering to ANSI VI leakage standards.
 

Convenience through Modular Design
The modular design of the inner sealing offers seamless interchangeability between soft and metal seats, ensuring flexibility and adaptability for varied applications.

Versatile Connection Types for Ease of Use
Our valves feature a range of connection types, including flanged (RF, FF, FM, G, RJ), screw-thread, and BW types, all of which are internationally recognized standards. This ensures maximum user convenience and operational flexibility.

Proven Reliability Through Extensive Experience
SNT Valves are deployed across numerous sectors such as petroleum, chemical, light industry, pharmacy, paper-making, metallurgy, and power stations. Our esteemed reputation in the market is built upon providing reasonable solutions tailored to specific service conditions, guaranteeing reliability and customer satisfaction.

 

Structural Features

Our exceptional packing combination is meticulously crafted to meet stringent emission requirements of 100 ppm, while ingeniously reducing stem friction by an impressive 20%. This ensures unparalleled efficiency and longevity.

1. Our innovative anti-blowout design is engineered to prevent the stem from blowing out, thereby safeguarding against potential damage and ensuring uninterrupted operation.

2. The seat ring features a sophisticated wave spring and dual-scraper structure, expertly designed to meticulously clean the ball surface, thus maintaining an impeccable seal for optimum performance.

3. The dual-sealing mechanism is meticulously designed to achieve an exceptional leakage class, effectively preventing flow from contacting the spring, thereby ensuring reliability and peace of mind.

4. The design of our soft seat sealing is engineered for superior stability and reliability, offering a consistently high-performing and dependable solution.
