Product Description

 

Experience unparalleled assurance with the Floating Ball Valve featuring A351CF8M, expertly crafted by SNT Machinery (Qingdao) Co., Ltd. This series guarantees Zero-Leakage performance across a spectrum of service applications, deftly handling conditions of high temperature and/or high pressure with precision and reliability.
Engineered for exceptional durability, the ball and seat are fortified with hard coatings of chrome carbide or tungsten carbide. These materials are renowned for their superior erosion and abrasion resistance, ensuring longevity and sustained performance in challenging environments.
SNT employs an advanced HVOF coating system, meticulously mate-lapped using proprietary techniques to guarantee 100% sealing. Live loading further assures zero emissions. Ingeniously designed, the ball remains in constant contact with the seat, effectively wiping away contaminants. This self-cleaning mechanism prevents interference and damage from foreign particles, making our valve ideally suited for slurry and abrasive services.

 

 

 

 

 

Our Advantages

 

SNT Ball Valves are meticulously engineered to adhere to prominent international standards including ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009, among others. These superior products are extensively utilized across diverse sectors such as petroleum, chemical industry, light industry, pharmaceuticals, paper production, metallurgy, and power stations.

Distinctive Features of Our Ball Valves:
Ingenious construction ensures rapid disassembly,
With routine maintenance in mind, our ball valves are crafted for uncomplicated servicing. The non-tight fit design significantly reduces maintenance time, enhancing operational efficiency.

State-of-the-Art Sealing for Uncompromised Security,
The innovative multi-layer combined sealing system between the stem and body provides dual sealing capabilities, employing a strategic combination of O-ring and graphite or PTFE for maximum effectiveness.
This sophisticated design is compliant with TA-Luft and Shell SPE 77/312 standards.

Extended Durability for Cost-Effective Operations,
In our metal-sealed ball valves, we utilize cutting-edge processing techniques such as spray welding, spraying, and fusion welding on the ball and seat ring. This ensures a hardness of HRC58-73 and a binding force of 80-40MPa. Remarkably, these valves can perform over 100,000 on-off cycles, boasting a leakage class of ANSI VI.

Streamlined Modular Design for User Convenience,
The adaptable modular design of the inner sealing allows for easy interchangeability between soft and metal seats, ensuring optimal performance.

Versatile Connection Options for Effortless Use,
Our extensive range of connection types-including flanged (RF, FF, FM, G, RJ), screw-thread, and BW types-are widely recognized and facilitate seamless integration.

Proven Expertise for Trusted Reliability,
Backed by extensive application experience, SNT Valves are trusted across industries such as petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations. Our stellar reputation is built on providing sound, practical solutions tailored to specific service conditions.

Structural Features

 

Our innovative packing combination excels by meeting stringent emission standards with a 100 ppm requirement, all while reducing friction against the stem by an impressive 20%!

1. Ingeniously designed anti-blowout feature ensures the stem remains securely in place, safeguarding against potential damage and operational failures.

2. The sophisticated wave spring and dual-scraper seat ring design actively cleans the ball surface, maintaining superior sealing integrity and performance.

3. With dual-sealing technology at its core, our valve effectively ensures that the flow is isolated from the spring, guaranteeing impeccable leakage class standards.

4. Experience unparalleled reliability and stability with our soft seat's sealing performance, crafted for consistency and precision.

5. The intelligent draining and sweeping design effectively prevents jamming, ensuring the valve remains clean and operationally efficient.

6. Fully compliant with API 607 standards, our product boasts robust fire-proof and anti-static functionalities for unmatched safety and security.
