Product Description

Introducing our exceptional series of high-performance ball valves, each engineered to deliver unparalleled Zero-Leakage performance across a spectrum of demanding service applications, including those requiring resilience to high temperatures and high pressure.
The core components, namely the ball and seat, are meticulously hard-coated with premium chrome carbide or tungsten carbide. This specialized coating ensures exceptional resistance to erosion and abrasion, offering durability and reliability under the most severe conditions.
At SNT Machinery (Qingdao) Co., Ltd., we employ a state-of-the-art HVOF coating system. Through our proprietary mate-lapping technique, we achieve impeccable 100% sealing. The live loading feature further ensures zero emissions, providing an eco-friendly solution. The ingenious design keeps the ball consistently engaged with the seat, effectively wiping away contaminants. This innovative self-cleaning mechanism safeguards against interference and damage from debris, making these valves optimal for slurry and abrasive service applications.

 

Our Advantages

SNT Ball Valves are meticulously crafted to comply with an array of international standards, such as ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009, ensuring top-tier quality. This versatile series of products finds its application across a broad spectrum of industries, including petroleum, chemical industry, light industry, pharmacy, paper-making, metallurgy, and power stations.

They boast the following exceptional characteristics:
Ingeniously simple structure facilitates rapid disassembly.
Thanks to regular maintenance protocols, our ball valves are designed for easy upkeep with a non-tight fit design, significantly reducing servicing time.

State-of-the-art sealing ensures unparalleled security.
The sophisticated multi-layer sealing of the stem and body provides dual sealing through the combination of an O-ring with either graphite or PTFE.
This innovative design adheres to TA-Luft and Shell SPE 77/312 standards.

Extended service life delivers exceptional cost-effectiveness.
For metal-sealed ball valves, cutting-edge processing techniques like spray welding, spraying, and fusion welding are employed for the ball and seat ring, achieving hardness levels of HRC58-73 and binding forces of 80-40MPa. This ensures over 100,000 on-off cycles with a leakage class rated at ANSI VI.
 

Our modular design ensures utmost convenience.
The innovative modular design of the inner sealing allows for interchangeability between soft and metal seats to ensure flexibility.

Diverse connection types enhance user experience.
The array of connection types, including flanged (RF, FF, FM, G, RJ), screw-thread, and BW types, are globally recognized, providing ultimate convenience in usage.

Extensive application experience guarantees reliability.
SNT Valves are extensively utilized in petroleum, chemical industry, light industry, pharmacy, paper-making, metallurgy, and power station sectors. Our stellar reputation in the market is built on providing well-founded solutions tailored to specific service conditions.

 

Structural Features

Our innovative packing combination excels by meeting the stringent emission requirements of 100 ppm. This advance not only ensures compliance but also ingeniously reduces stem friction by a remarkable 20%, significantly enhancing the overall efficiency and longevity of our valves.

1. Expertly designed with an anti-blowout feature, our valves ensure that the stem remains securely in place, effectively preventing any potential damage caused by stem blowout.

2. Featuring an advanced seat ring structure with wave spring and dual-scraper technology, our valves proficiently cleanse the ball surface, thereby maintaining impeccable sealing integrity.

3. The ingenious dual-sealing design confidently upholds the leakage class by ensuring that the fluid flow is strategically isolated from contacting the spring, maximizing performance and reliability.

4. Our soft seat sealing performance stands out for its exceptional stability and reliability, providing peace of mind with every operation.

5. The meticulously engineered design for draining and sweeping ensures our valves are resistant to jamming, maintaining optimal functionality by effectively cleaning the entire system.

6. Adhering to the rigorous API 607 standards, our valves offer robust fire-proof and anti-static features, ensuring maximum safety and operational integrity.
