Product Description

 

Dive into the world of precision and performance with our Soft Seated Floating Ball Valve, engineered by SNT Machinery (Qingdao) Co., Ltd. This remarkable series offers Zero-Leakage ball valves tailored for numerous service applications, seamlessly accommodating both high temperature and high pressure scenarios.
Our valves boast a ball and seat that are meticulously hard coated with robust materials such as chrome carbide or tungsten carbide. This innovative coating ensures exceptional resistance to erosion and abrasion, providing the durability you require for demanding environments.
SNT employs an advanced HVOF coating system, ensuring each valve is mate-lapped using our proprietary technique for impeccable 100% sealing. The live loading feature guarantees zero emissions. Ingeniously designed, the ball remains in constant contact with the seat, deftly sweeping away contaminants. This self-cleaning mechanism not only prevents interference and damage from foreign particles but also makes the valve an ideal choice for slurry and abrasive services.

 

 

 

 

 

Our Advantages

 

The design specifications of SNT Ball Valves align seamlessly with a wide array of international standards such as ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009, amongst others. These versatile products find extensive applications across various sectors including petrol, the chemical industry, light industry, pharmacy, paper-making, metallurgy, and power stations.

They boast the following exceptional characteristics:
The straightforward structure facilitates quick and easy disassembly.
Thanks to the periodic maintenance of all valves, our ball valves are designed for effortless maintenance. The non-tight fit design significantly reduces servicing time, enhancing efficiency.

State-of-the-art sealing ensures maximum security.
A multi-layered combined sealing system of the stem and body offers dual sealing capabilities through the integration of O-ring and graphite or PTFE, ensuring robust protection.
This innovative design adheres to TA-Luft and Shell SPE 77/312 standards, guaranteeing compliance and reliability.

Extended service life promotes cost-effectiveness.
For metal-sealed ball valves, advanced processing techniques like spray welding, spraying, and fusion welding are employed for the ball and seat ring. This ensures a hardness level of HRC58-73 and a binding force of 80-40MPa. Additionally, these valves can exceed 100,000 on-off cycles while maintaining an ANSI Class VI leakage standard.

The modular design enhances convenience.
With a modular design in inner sealing, the interchangeability between soft and metal seats is assured, providing versatile and adaptable solutions.

Multiple connection options ensure user-friendly operation.
Offering a diverse range of connection types, including flanged types (RF, FF, FM, G, RJ), screw-thread types, and BW types, these are internationally recognized standards that assure ease of use and convenience.

Our vast experience in application ensures reliability.
SNT Valves have been extensively implemented in petroleum, chemical industries, light industries, pharmacy, paper-making, metallurgy, and power stations. Our esteemed reputation is built on providing reasonable solutions tailored to specific service conditions, ensuring trust and reliability in the market.

Structural Features

 

A unique packing combination is engineered to achieve the emission requirement of 100 ppm while simultaneously reducing the friction against the stem by 20%, ensuring smoother operations.

1. The anti-blowout design effectively prevents the stem from being ejected, thereby safeguarding against potential damage and ensuring the integrity of the entire system.

2. The wave spring and dual-scraper seat ring construction cleans the ball surface efficiently, maintaining a tight seal for optimal performance.

3. Dual-sealing technology ensures outstanding leakage prevention by tactically directing flow away from the spring, thus enhancing reliability.

4. Soft seat sealing performance is remarkably stable and consistently reliable, providing peace of mind for critical applications.

5. The strategic design of draining and sweeping mechanisms prevents blockage by effectively cleaning the valve, ensuring uninterrupted function.

6. Adhering to API 607 standards, the valve features robust fire-proof and anti-static capabilities, meeting high safety and performance requirements.
