Product Description

Our advanced series of Heavy Duty Control Valves and Ball Valves for Water and Gas delivers unrivaled performance with Zero-Leakage technology, expertly engineered for a variety of demanding service applications. These valves are designed to withstand both high temperature and high-pressure environments, ensuring reliability and safety in the most challenging conditions.
The ball and seat components are meticulously hard coated with premium materials such as chrome carbide or tungsten carbide. These coatings are chosen for their exceptional resistance to erosion and abrasion, providing unparalleled durability and longevity, even in the harshest operating conditions.
At SNT Machinery (Qingdao) Co., Ltd., we employ the cutting-edge HVOF coating system. Each component is precisely mate-lapped using our proprietary technique, guaranteeing 100% sealing integrity. Our innovative live loading feature further ensures zero emissions, maintaining an environmentally friendly operation. The ball remains consistently aligned with the seat, effectively wiping away contaminants in a self-cleaning motion. This sophisticated mechanism prevents any interference or damage caused by foreign particles, making this valve perfectly suited for handling slurry and abrasive services with ease and efficiency.

 

Our Advantages

SNT Ball Valves' design specifications are meticulously crafted to adhere to a plethora of esteemed international standards including ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009, among others. This exceptional series of products finds extensive application in numerous industries such as petroleum, chemical, light industry, pharmacy, paper-making, metallurgy, and power stations, showcasing its unparalleled versatility and reliability.

They boast the following superior features:
Ingenious simplicity defines our structure, facilitating swift disassembly and reassembly with remarkable ease.
Thanks to the regular maintenance schedule for all our valves, our ball valves are engineered for effortless upkeep. The non-tight fit design significantly reduces servicing time, optimizing efficiency.

Sophisticated sealing technology ensures uncompromised safety and security.
The multi-layered sealing system, incorporating both the stem and body, provides a robust double sealing mechanism through an innovative blend of O-rings and materials such as graphite or PTFE, ensuring maximum leak prevention.
This advanced design meets the stringent requirements of TA-Luft and Shell SPE 77/312 standards, assuring top-notch environmental and operational compliance.

Extended service life translates to remarkable cost-effectiveness, providing enduring value.
In metal-sealed ball valves, cutting-edge techniques like spray welding, spraying, and fusion welding are employed on the ball and seat ring. This ensures an exceptional hardness ranging from HRC58 to 73, alongside a binding force of 80 to 40MPa. Furthermore, the on-off cycle exceeds 100,000 times, with leakage classified to the high standards of ANSI VI.
 

The modular design underscores user convenience and adaptability.
Our innovative modular design of the inner sealing allows for easy interchangeability between soft and metal seats, providing flexibility and ensuring optimal performance.

Diverse connection options ensure user-friendly operation.
We offer multiple international connection types, including flanged variants (RF, FF, FM, G, RJ), screw-threaded, and BW types, delivering unmatched convenience and adaptability to diverse usage scenarios.

Rich expertise in application delivers unwavering reliability.
SNT Valves are extensively utilized across various sectors such as petroleum, chemical industry, light industry, pharmacy, paper-making, metallurgy, and power stations. Our stellar reputation in the market is built on providing well-founded solutions tailored to specific service conditions, ensuring customer satisfaction and trust.

 

Structural Features

The innovative packing combination is engineered to meet stringent transmission requirements of 100 ppm. This cutting-edge design also boasts a 20% reduction in friction at the stem, ensuring smooth and efficient operation.

1. The advanced anti-blow out design is crafted to ensure the stem remains securely in place, preventing any potential damage from blowouts.

2. Featuring a wave spring and dual-scraper seat ring, this structure is adept at keeping the ball surface impeccably clean, thereby maintaining an exceptional seal.

3. Our dual-sealing system is meticulously designed to achieve unparalleled leakage control by ensuring the flow never comes into contact with the spring.

4. The sealing performance of our soft seat is engineered to deliver consistent stability and unwavering reliability.

5. The intelligently designed draining and sweeping features effectively prevent valve jamming by thoroughly cleaning the system.

6. Fully compliant with API 607 standards, our valves are equipped with fire-proof and anti-static functions, ensuring superior safety and performance.
