Product Description

 

Experience the ultimate in reliability with our High Performance Shutoff Ball Valve, designed to deliver Zero-Leakage across a variety of demanding service applications. Whether you're dealing with high temperature or high-pressure environments, this series of ball valves ensures unwavering performance and peace of mind.
Crafted with precision, the ball and seat feature a robust hard coating of chrome carbide or tungsten carbide. This advanced coating provides exceptional resistance to erosion and abrasion, significantly extending the valve's longevity and reliability in the toughest conditions.
At SNT Machinery (Qingdao) Co., Ltd., we employ an advanced HVOF coating system to enhance durability. Our proprietary mate-lapping technique guarantees an impeccable 100% seal. Featuring live loading, our valves ensure zero emissions. The ball seamlessly remains seated, effectively wiping away contaminants with its self-cleaning action, thus preventing any interference or damage. This remarkable capability makes our valve the perfect choice for handling slurry and abrasive services with ease and efficiency.

 

 

 

 

 

Our Advantages

 

SNT Ball Valves are meticulously engineered to adhere to an array of prestigious international standards, including ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009. This versatile series of valves is extensively utilized across various industries such as petroleum, chemical processing, light manufacturing, pharmaceuticals, paper production, metallurgy, and power generation.

Our Valves Exhibit the Following Elite Characteristics:
The simplified structure ensures effortless and rapid disassembly.
Thanks to routine maintenance protocols, our ball valves are designed with a non-tight fit, facilitating easy maintenance and significantly reducing servicing time.

Advanced Sealing Technology Ensures Uncompromising Security
Our multi-layered sealing system between the stem and body provides exceptional double sealing through a strategic combination of O-ring and materials like graphite or PTFE.
This innovative design complies with the rigorous TA-Luft/Shell SPE 77/312 standards.

Extended Service Life for Enhanced Cost Efficiency
In metal-sealed ball valves, we employ cutting-edge techniques such as spray welding, thermal spraying, and fusion welding for the ball and seat ring. This ensures an impressive hardness range of HRC58-73 and a binding force between 80-40MPa. These valves boast durability with over 100,000 on-off cycles and meet the ANSI VI leakage class.

Modular Design Offers Elevated Convenience
Our modular inner sealing design provides the flexibility to interchange soft and metal seats, ensuring adaptability and efficiency.

Diverse Connection Types for Optimal Usability
Offering various connection types, including flanged (RF, FF, FM, G, RJ), screw-thread, and BW types, these globally standardized options ensure ease and convenience in application.

Our Extensive Application Experience Guarantees Reliability
SNT Valves are prominently employed across industries like petroleum, chemicals, light manufacturing, pharmaceuticals, paper production, metallurgy, and power sectors. We are well-regarded in the market for providing robust, tailored solutions based on specific service conditions.

Structural Features

 

Our unique special packing combination is engineered to meet the stringent smission requirement of 100 ppm while simultaneously reducing friction on the stem by an impressive 20%. This innovation ensures smoother operations and enhanced product longevity.

1. Our advanced anti-blowout design effectively prevents any potential damage by ensuring the stem remains securely in place, safeguarding the integrity of the entire system.

2. Featuring a sophisticated seat ring structure with a wave spring and dual-scraper, this valve effectively cleans the ball surface, ensuring pristine conditions and maintaining an optimal seal.

3. Dual-sealing technology enhances the reliability of leakage prevention, ensuring that the flow remains isolated from the spring, thereby maintaining high leakage class standards.

4. The soft seat design offers superior stability and reliability, providing consistent and dependable sealing performance, even under challenging conditions.

5. Innovative draining and sweeping design effectively prevents valve jamming, ensuring smooth, trouble-free operations by maintaining cleanliness within the system.

6. Designed in compliance with API 607 standards, our shutoff ball valve boasts fire-proof and anti-static capabilities, delivering enhanced safety and reliability in demanding environments.
