Product Description

^{Introducing the High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. These valves are meticulously engineered to deliver exceptional Zero-Leakage performance, making them ideal for a wide range of high-temperature and high-pressure service applications. Experience ultimate reliability and precision with our expertly crafted valves.
Crafted with unparalleled precision, the ball and seat of these valves are fortified with advanced hard coatings, featuring either chrome carbide or tungsten carbide. This superior enhancement ensures remarkable resistance against both erosion and abrasion, significantly boosting the valves' longevity and dependability.
Our SNT High Performance Soft Seated Ball Valves feature a cutting-edge HVOF coating system. Each valve is subject to meticulous mate-lapping using proprietary techniques, ensuring flawless 100% sealing. The innovative live loading feature guarantees zero emissions, while the ball's constant contact with the seat effectively cleans contaminants. This advanced self-cleaning mechanism prevents particle interference and damage, making these valves the perfect solution for slurry and abrasive service applications.}

Structure Features

 

<sup>Our unique special packing combination not only meets the stringent emission requirements of 100 ppm but also ingeniously reduces stem friction by an impressive 20%.

The innovative anti-blowout design is meticulously crafted to prevent stem ejection, thereby safeguarding against potential damage and ensuring operational safety.

Engineered with precision, the seat ring structure featuring a wave spring and dual-scraper system effectively cleans the ball surface while maintaining an impeccable seal.

The advanced dual-sealing mechanism ensures superior leakage protection by expertly preventing flow contact with the spring, thereby securing the leakage class.</sup>

Experience the enhanced and dependable sealing performance of our meticulously crafted soft seat, which offers unmatched stability and reliability.

The thoughtfully designed draining and sweeping system is expertly constructed to prevent valve jamming, ensuring uninterrupted operation through efficient cleaning.

Our products proudly comply with API 607 standards, offering robust fire-proof and anti-static features for enhanced safety and durability.
