Product Description

 

Introducing the exceptional Soft Seated Ball Valve, meticulously crafted by SNT Machinery (Qingdao) Co., Ltd., to deliver unparalleled Zero-Leakage capabilities across a multitude of challenging service applications. This series is engineered to effortlessly handle the most demanding environments, ensuring superior performance even under high temperature and high pressure conditions.
The ball and seat of our Soft Seated Ball Valve are fortified with a premium hard coating of chrome carbide or tungsten carbide. This advanced coating offers remarkable resistance to erosion and abrasion, ensuring long-lasting durability and reliability in aggressive and challenging service conditions.
At SNT, we employ a cutting-edge HVOF coating system, paired with our proprietary mate-lapping technique, to achieve an impeccable 100% seal. Our innovative live loading design guarantees zero emissions, while the ball remains perfectly seated, methodically wiping away any contaminants. This self-cleaning mechanism effectively protects against interference and damage, making our valve ideal for slurry and abrasive service applications.

 

 

 

 

 

Our Advantages

 

SNT Ball Valves are meticulously crafted to adhere to an array of prestigious international standards including ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009. This remarkable series of valves is extensively employed across diverse sectors such as petroleum, chemical industries, light industry, pharmaceuticals, paper-making, metallurgy, and power stations, showcasing their versatile application.

They possess the following distinctive characteristics:
Innovative and Simple Structure Ensures Quick Disassembly
Thanks to the periodic maintenance design, our ball valves facilitate effortless upkeep with a non-tight fit structure, significantly reducing servicing time and enhancing efficiency.

State-of-the-Art Sealing Mechanism Assures Unparalleled Security
The multi-layer combined sealing of the stem and body provides dual security through a sophisticated combination of O-ring and graphite or PTFE, ensuring reliability and safety.
This sophisticated design complies with TA-Luft and Shell SPE 77/312 standards.

Extended Service Life Delivers Unmatched Cost-Effectiveness
Our metal-sealed ball valves are engineered with advanced processing techniques such as spray welding, spraying, and fusion welding. These methods guarantee a remarkable hardness range of HRC58-73 and a binding force of 80-40MPa. Consequently, the on-off cycles exceed 100,000 with a leakage class that conforms to ANSI VI standards.

Convenience Through Modular Design
The modular design of the inner sealing system offers seamless interchangeability between soft and metal seats, enhancing adaptability and efficiency.

Versatile Connection Types for Enhanced User Comfort
Our valve connection types include internationally recognized standards such as flanged type (RF, FF, FM, G, RJ), screw-thread type, and BW type, ensuring ease and convenience of use.

Extensive Application Experience Ensures Unwavering Reliability
SNT Valves have been extensively implemented in petroleum, chemical industries, light industry, pharmaceuticals, paper-making, metallurgy, and power stations. Renowned for our stellar market reputation, we provide judicious solutions tailored to specific service conditions, ensuring reliability and trust.

Structural Features

 

Our innovative special packing combination is meticulously engineered to fulfill the stringent emission requirement of 100 ppm. It simultaneously delivers a significant 20% reduction in friction to the stem, ensuring superior performance and longevity.

1. The robust anti-blowout design is an ingenious feature that effectively prevents any accidental stem blowout, safeguarding against potential damage and enhancing operational safety.

2. The advanced structure of the seat ring, incorporating a wave spring and dual-scraper, ensures continuous cleaning of the ball surface. This design maintains impeccable sealing integrity and prolongs product lifespan.

3. Our dual-sealing mechanism is expertly crafted to uphold the highest leakage class standards by preventing the flow from coming into contact with the spring, ensuring unrivaled leakage protection.

4. The sealing performance of our soft seat design is engineered for exceptional stability and reliability, delivering consistent and dependable sealing throughout its service life.

5. The innovative design of draining and sweeping ensures the valve remains free from jamming, employing a thorough cleaning process to maintain optimal functionality.

6. Crafted to comply with API 607 standards, our product features exemplary fire-proof and anti-static functionalities, offering enhanced safety and reliability even in the most demanding environments.
