Introducing our cutting-edge series of Zero-Leakage Ball Valves, meticulously crafted for a myriad of demanding service applications. Designed to excel under high temperature and high-pressure conditions, these valves promise unmatched reliability and performance.
Our ball and seat components are fortified with an exceptional hard coating of chrome carbide or tungsten carbide, offering unrivaled resistance against erosion and abrasion. This ensures that our valves are robust and enduring, even in the most challenging environments.
At SNT Machinery (Qingdao) Co., Ltd., we employ an advanced HVOF coating system. Through our proprietary mate-lapping technique, we guarantee a flawless 100% seal. The dynamic live loading feature ensures absolute zero emissions. Ingeniously designed, the ball remains in constant contact with the seat, effectively wiping away any contaminants. This innovative self-cleaning action prevents any interference or damage, making our valve an ideal choice for demanding slurry and abrasive services.
At SNT Machinery (Qingdao) Co., Ltd., our High Performance Full Shutoff Ball Valves are meticulously engineered to adhere to a spectrum of international benchmarks such as ASME B 16.34-2009, ASME B16.10-2000, API 589-2009, and more. These premier valves are purposefully crafted for diverse applications across industries including petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations.
Our ball valves boast the following distinctive features:
A straightforward structure facilitates swift and effortless disassembly.
Thanks to regular maintenance protocols, our ball valves ensure simplified upkeep with a non-tight fit design, significantly minimizing the time required for service.
Our advanced sealing technology ensures unparalleled safety and protection.
The multi-layer sealing system, combining O-ring and either graphite or PTFE, provides robust double sealing between the stem and body.
This innovative design is compliant with TA-Luft/Shell SPE 77/312 standards.
Extended service life enhances cost efficiency.
For our metal-sealed ball valves, sophisticated techniques such as spray welding, spraying, and fusion welding are employed, achieving an impressive hardness of HRC58-73 and a binding force between 80-40MPa. This ensures more than 100,000 on-off cycles with leakage class conforming to ANSI VI.
The modular design brings unparalleled convenience.
The interchangeable inner sealing system allows for the versatility of both soft and metal seats to meet various requirements.
Multiple connection types ensure ease of use.
Connection options include flanged types (RF, FF, FM, G, RJ), screw-thread, and BW types that are universally recognized and facilitate seamless operability.
Our extensive experience in diverse applications underscores our reliability.
SNT Valves enjoy a stellar reputation, having been extensively applied in petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power station sectors. We reliably provide tailored solutions based on specific service conditions, earning trust and acclaim in the market.
Our advanced packing combination is engineered to meet stringent emission requirements of 100 ppm. Simultaneously, this innovative design effectively reduces friction by 20%, ensuring optimal performance in the stem.
1. The state-of-the-art anti-blow out design provides robust protection, ensuring that the stem remains securely in place, preventing any potential damage or malfunction.
2. Featuring a sophisticated seat ring structure with a wave spring and dual-scraper, this system expertly cleans the ball surface while maintaining an impeccable seal, enhancing durability and efficiency.
3. Our dual-sealing technology guarantees superior leakage protection by ensuring that the flow does not come into contact with the spring, affording you peace of mind and reliability.
4. The soft seat's sealing performance is both exceptionally stable and reliable, providing consistent and dependable results under a variety of conditions.
5. The inclusion of draining and sweeping functions effectively prevents the valve from becoming jammed, ensuring it remains clean and operational at all times.
6. Our design complies with API 607 standards, offering advanced fire-proof and anti-static features for enhanced safety and performance in demanding applications.
