Product Description

 

Introducing our exceptional series of Zero-Leakage ball valves, meticulously engineered for a multitude of service applications, especially where high temperature and high pressure are prevalent. This series represents the pinnacle of precision and reliability.
The ball and seat within our valves are fortified with a robust hard coating of chrome carbide or tungsten carbide, renowned for their superior resistance to erosion and abrasion. This advanced treatment ensures durability and longevity under the most demanding conditions.
At SNT, we employ the cutting-edge HVOF coating system. With our proprietary mate-lapped technique, we guarantee 100% sealing integrity. The inclusion of live loading further assures zero emissions, maintaining environmental standards. Designed for optimal performance, the ball remains in constant contact with the seat, effortlessly wiping away contaminants. This self-cleaning mechanism protects against interference and potential damage from debris, making this valve the ideal choice for both slurry services and abrasive operations.

 

 

 

 

 

Our Advantages

 

SNT Ball Valves are crafted to meet an array of international standards such as ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009, among others. This versatile series of products is extensively applied across various industries including petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations.

Distinctive Features and Characteristics:
Ingenious, Simple Structure Ensures Effortless Disassembly
With regular maintenance intervals, our ball valves are designed for user-friendly servicing. The non-tight fit design reduces maintenance time, offering unparalleled convenience.

Innovative Sealing for Enhanced Security
The multi-layer combined sealing system of the stem and body provides robust double sealing with a blend of O-ring and graphite or PTFE, ensuring reliability.
This expertly crafted design complies with TA-Luft and Shell SPE 77/312 standards.

Extended Service Life for Unmatched Cost-Effectiveness
For metal-sealed ball valves, advanced 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 range of 80-40MPa, enabling over 100,000 on-off cycles with leakage class conforming to ANSI VI.

Modular Design Offers Supreme Flexibility
The innovative modular design of the inner sealing allows for interchangeable soft and metal seats, ensuring adaptability and seamless performance.

Diverse Connection Types for Optimal Ease of Use
Our valves offer various connection types, including flanged (RF, FF, FM, G, RJ), screw-thread, and BW types, all adhering to international standards, providing utmost convenience and ease of use.

Extensive Application Experience Guarantees Unshakable Reliability
SNT Valves are renowned for their widespread use in industries such as petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations. Our esteemed reputation in the market is built on delivering tailored solutions based on specific service conditions.

Structural Features

 

Our innovative packing combination is engineered to excel! It not only meets the stringent emission requirements of 100 ppm but also reduces stem friction by an impressive 20%.

1. Ingeniously crafted with an anti-blowout design, the valve prevents the stem from being ejected, thus safeguarding against potential damage.

2. Equipped with a wave spring and dual-scraper seat ring, our design ensures the ball surface is meticulously cleaned while maintaining impeccable sealing.

3. Dual-sealing technology is employed to ensure that the flow is isolated from the spring, guaranteeing an exceptional leakage class.

4. Experience unparalleled stability and reliability with the enhanced sealing performance of our soft seat.

5. The innovative draining and sweeping design actively prevents jamming by thoroughly cleaning the valve.

6. Our product is meticulously crafted to comply with API 607 standards, offering robust fire-proof and anti-static capabilities.
