Product Description

 

^{Introducing the High Performance Soft Seated Ball Valve series by SNT Machinery(Qingdao) Co., Ltd. Meticulously engineered, these valves deliver outstanding Zero-Leakage performance in diverse high-temperature and high-pressure service applications.
Crafted with unmatched precision, the ball and seat of these valves are reinforced with advanced hard coatings of chrome carbide or tungsten carbide. This superior fortification ensures exceptional resistance to both erosion and abrasion, enhancing longevity and reliability.
Our SNT High Performance Soft Seated Ball Valves incorporate a state-of-the-art HVOF coating system. Each valve undergoes meticulous mate-lapping using proprietary techniques to guarantee a flawless 100% sealing. The innovative live loading feature ensures zero emissions, while the ball remains in constant contact with the seat, effectively wiping away contaminants. This cutting-edge self-cleaning mechanism prevents interference and damage from particles, making these valves the perfect choice for slurry and abrasive service applications.}

 

 

 

 

 

Structure Features

 

<sup>Sepcial packing combination can meet the emission reuqirement of 100 ppm meanwhile reduce the friction by 20% to stem.

The design of anti-blow out canprevent the stem from blowing out to case damage.

The structure of seat ring of wave spring and dual-scraper can clean ball surface and keep sealing.

Dual-sealing can guarantee teh leacke class by making flow not to contact spring.</sup>
 

 

The sealing performance of soft seat is more stable and reliable,

The design of draining and sweeping can prevent valve form jammed by cleaining.

Comply with API 607 standards with the functions of fire-prood and anti-Static.

Our Advantages

 

SNT Ball Valves are meticulously engineered to comply with a multitude of international standards, including ASME B16.34-2009, ASME B16.10-2000, and API 589-2009. This versatile series finds extensive applications across various industries such as petroleum, chemical industry, light industry, pharmaceuticals, paper-making, metallurgy, and power stations.

Their Outstanding Features Include:
Streamlined design for effortless disassembly.
Designed with ease of maintenance in mind, our ball valves feature a non-tight fit design that facilitates quick servicing, minimizing downtime during periodic maintenance.

Cutting-edge sealing technology for maximum security.
The multi-layer sealing of stem and body delivers dual protection through a combination of O-ring and graphite or PTFE, ensuring exceptional sealing performance.
This innovative design meets the rigorous TA-Luft/Shell SPE 77/312 standards.

Extended Service Life for Superior Cost-Efficiency
Our metal seated ball valves undergo advanced processing techniques such as spray welding, spraying, and fusion welding.
