Product Description

Introducing our exceptional series of Zero-Leakage ball valves, expertly designed to thrive in demanding service applications characterized by both high temperature and high pressure. These valves are engineered to deliver flawless performance, ensuring no leaks even in the most challenging conditions.
Our ball and seat components are meticulously hard coated with premium materials such as chrome carbide or tungsten carbide. This advanced coating provides superior erosion and abrasion resistance, extending the longevity and reliability of the valves.
At SNT, we employ an innovative HVOF coating system, coupled with our proprietary mate-lapping technique to guarantee a perfect 100% seal. Our valves feature live loading to ensure zero emissions, and a unique design where the ball remains in constant contact with the seat, effectively wiping away contaminants. This self-cleaning mechanism prevents interference and damage from debris, making these valves ideal for both slurry and abrasive service applications.

 

Our Advantages

The SNT Ball Valves are crafted to perfection, adhering rigorously to an array of esteemed international standards such as ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009. With such robust compliance, these exceptional valves find their applications across diverse industries including petrochemicals, chemical processing, light manufacturing, pharmaceuticals, paper production, metallurgy, and power generation.

They possess the following outstanding characteristics:
A simplified structure that facilitates quick and effortless disassembly.
Thanks to the periodic maintenance of every valve, our ball valves are designed for ease of upkeep. The non-tight fit design significantly reduces servicing time, making maintenance a breeze.

Ingenious sealing technology ensures unparalleled security.
The multi-layer combined sealing of both the stem and the body delivers a dual seal through a sophisticated amalgamation of O-ring with graphite or PTFE, ensuring superior security.
This innovative design fulfills the stringent TA-Luft and Shell SPE 77/312 standards.

Extended service life ensures economic efficiency.
Our metal-sealed ball valves undergo advanced processing techniques such as spray welding, spraying, and fusion welding, enhancing the hardness to HRC58-73 and the binding force to 80-40MPa. These enhancements enable the valves to perform over 100,000 on-off cycles while maintaining a leakage class of ANSI VI, ensuring durability and cost-effectiveness.
 

Modular design simplifies operations.
The innovative modular design of inner sealing allows for the interchangeability of soft and metal seats, ensuring flexibility and ease of use.

Diverse connection types enhance usability.
With a variety of connection types such as flanged (RF, FF, FM, G, RJ), screw-thread, and BW type, these valves are designed for seamless international compatibility and user convenience.

Extensive application experience provides unmatched reliability.
The SNT Valves are a trusted choice across industries like petroleum, chemical processing, light manufacturing, pharmaceuticals, paper production, metallurgy, and power stations. Our esteemed reputation in the market is built on delivering sound solutions tailored to specific service conditions, ensuring reliability.

 

Structural Features

The innovative special packing combination is ingeniously crafted to meet the stringent transmission requirements of 100 ppm, while simultaneously reducing stem friction by an impressive 20%, enhancing operational efficiency and longevity.

1. The robust anti-blowout design effectively prevents the stem from being blown out, thereby safeguarding against potential damage, ensuring safety, and reliability in every operation.

2. The advanced structure of the seat ring, featuring a wave spring and dual-scraper, meticulously cleans the ball surface, maintaining optimal sealing and ensuring flawless performance, even in the most demanding conditions.

3. Our dual-sealing mechanism assures an impeccable leakage class by expertly preventing the flow from contacting the spring, thereby enhancing the integrity and durability of our valves.

4. The soft seat sealing performance is engineered for superior stability and reliability, providing consistent and dependable operation.

5. Innovative design features for draining and sweeping efficiently prevent the valve from becoming jammed, ensuring uninterrupted and smooth functionality through effective cleaning.

6. Adhering to API 607 standards, our valves incorporate exemplary fire-proof and anti-static functions, offering a higher level of safety and trust you can depend on.
