Product Description

Discover the unparalleled excellence of our Full Bore Control Valves and Ball Valves for Maximum Flow Efficiency. Specifically designed to deliver Zero-Leakage performance, these ball valves are engineered to excel in various demanding service applications, whether you're dealing with high temperatures or high pressures.
Experience superior durability with our valves, featuring a ball and seat that are meticulously hard-coated with either chrome carbide or tungsten carbide. These coatings provide exceptional resistance to erosion and abrasion, ensuring long-lasting performance even in the harshest conditions.
At SNT Machinery (Qingdao) Co., Ltd., we utilize an advanced HVOF coating system to create a perfect mate-lapped finish using our proprietary technique. This guarantees absolute 100% sealing effectiveness. Our innovative live loading further ensures zero emissions, while the ball remains in constant contact with the seat, effectively wiping away any contaminants. This self-cleaning mechanism not only protects against interference and damage but also makes these valves ideal for slurry and abrasive service applications. Embrace the reliability and efficiency of valves designed for optimum performance.

 

Our Advantages

The SNT Ball Valves are meticulously crafted to align with an array of esteemed international standards including ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009. This diverse series of valves finds extensive application across a multitude of industries including petroleum, chemical manufacturing, light industrial sectors, pharmaceuticals, paper production, metallurgy, and power generation.

They feature the following exceptional characteristics:
A straightforward construction allows for rapid disassembly, ensuring user-friendly maintenance.
Thanks to the routine maintenance schedule, our ball valves facilitate easy servicing with a non-tight fit design that significantly reduces maintenance time.

Cutting-edge sealing technology ensures unparalleled security.
The multi-layered combined sealing system of both stem and body delivers dual sealing protection, achieved through a sophisticated blend of O-ring and high-quality graphite or PTFE.
This innovative design complies with TA-Luft/Shell SPE 77/312 standards.

Extended service life offers remarkable cost-efficiency.
For metal-sealed ball valves, advanced techniques such as spray welding, spraying, and fusion welding are employed on the ball and seat ring. This ensures a hardness ranging from HRC58-73 and a binding force between 80-40MPa, facilitating over 100,000 on-off cycles with a leakage class rated at ANSI VI.
 

The modular design delivers unmatched convenience.
Featuring a modular inner sealing design, these valves allow for the interchangeability of soft and metal seats, ensuring optimal adaptability.

Various connection types provide superior usability and comfort.
The available connection types include flanged (RF, FF, FM, G, RJ), screw-thread, and BW configurations, adhering to international standards to ensure ease of use and installation.

Vast experience in diverse applications guarantees reliability.
SNT Valves are extensively utilized in sectors such as petroleum, chemical processing, light industry, pharmaceuticals, paper manufacturing, metallurgy, and power stations. Renowned for our market reputation, we offer sound, reasonable solutions tailored to specific service conditions.
