Product Description

Introducing our series of Zero-Leakage ball valves, designed specifically for an array of service applications requiring resilience under high temperature and high-pressure conditions. Our engineering excellence ensures optimal performance and reliability for all your critical application needs.
The ball and seat are meticulously hard-coated with premium chrome carbide or tungsten carbide, providing exceptional resistance to erosion and abrasion. This robust construction guarantees longevity and dependable performance even in the harshest environments.
At SNT, we employ a state-of-the-art HVOF coating system perfected through our proprietary techniques. This ensures 100% sealing via mate-lapped surfaces for precision fit. Our innovative live loading mechanism further guarantees zero emissions. The ball remains in constant contact with the seat, effectively wiping away contaminants. This ingenious self-cleaning feature prevents damage and interference from contaminants, making these valves ideal for slurry and abrasive service applications.

 

Our Advantages

SNT Ball Valves are meticulously crafted to align with a diverse array of international standards such as ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009. This premium range is celebrated across industries including petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations, exemplifying versatility and excellence.

These valves are distinguished by the following remarkable features:
Their straightforward structure facilitates rapid disassembly, enhancing operational efficiency.
Our ball valves are designed for effortless maintenance, thanks to their non-tight fit design, which significantly reduces servicing time during scheduled maintenance.

State-of-the-art sealing technology ensures unparalleled security.
The innovative multi-layer sealing combines O-ring with graphite or PTFE, delivering robust dual sealing of both stem and body.
This sophisticated design complies with rigorous TA-Luft/Shell SPE 77/312 standards, ensuring maximum reliability.

Extended service life contributes to significant cost savings.
For metal-sealed ball valves, we employ advanced techniques like spray welding and fusion welding for the ball and seat ring. This ensures a hardness range of HRC58-73 and a binding force of 80-40MPa. The valves offer more than 100,000 on-off cycles and achieve an ANSI VI leakage class, setting a benchmark for durability.
 

Our modular design provides unmatched convenience.
The inner sealing's modular design allows for seamless interchangeability between soft and metal seats, ensuring flexibility and adaptability.

A variety of connection types ensures user-friendly experience.
Internationally recognized connection types including flanged (RF, FF, FM, G, RJ), screw-thread, and BW types are available, ensuring ease of use and global compatibility.

Extensive application experience underpins our reliability.
SNT Valve has forged a strong reputation across diverse industries such as petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations. We deliver trustworthy solutions tailored to specific service conditions, earning widespread market confidence.

 

Structural Features

The innovative special packing combination we offer is engineered to meet stringent emission requirements of up to 100 ppm. Simultaneously, it significantly reduces friction against the stem by 20%, ensuring smoother operation and enhanced durability.

1. Our advanced anti-blow out design effectively prevents the stem from being ejected, thereby eliminating potential damage and ensuring safety.

2. Featuring a wave spring seat ring and dual-scraper structure, our design adeptly cleans the ball surface and maintains an impeccable seal for superior performance.

3. The dual-sealing system is expertly crafted to uphold the highest leakage class, meticulously preventing the flow from contacting the spring, ensuring optimal integrity.

4. Experience the unparalleled stability and reliability of our soft seat's sealing performance, offering consistent protection and peace of mind.

5. Our draining and sweeping design innovation effectively prevents the valve from becoming jammed, by ensuring efficient cleaning and maintenance.

6. Designed in strict compliance with API 607 standards, our products boast robust fire-proof and anti-static functionalities, delivering premium safety and performance.
