Product Description

^{Introducing the High Performance Soft Seated Ball Valve series, proudly brought to you by SNT Machinery (Qingdao) Co., Ltd. These expertly engineered valves are designed to deliver unparalleled Zero-Leakage performance across a range of demanding high-temperature and high-pressure service applications.
Engineered with exquisite precision, the ball and seat within these valves are fortified with advanced hard coatings of chrome carbide or tungsten carbide. This unique enhancement offers extraordinary resistance to both erosion and abrasion, thereby significantly extending the longevity and ensuring reliability of the valves.
Our SNT High Performance Soft Seated Ball Valves are equipped with a cutting-edge HVOF coating system. Each valve is subjected to precise mate-lapping through proprietary techniques, ensuring a flawless 100% sealing capability. The innovative live loading feature guarantees zero emissions as the ball maintains constant contact with the seat, effectively eliminating contaminants. This state-of-the-art self-cleaning mechanism prevents interference and damage from particles, making these valves the ideal solution for slurry and abrasive service applications.}

Structure Features

 

<sup>Our innovative special packing combination not only meets the stringent emission requirement of 100 ppm but also ingeniously reduces friction by 20% to the stem, ensuring enhanced performance and longevity.

The meticulously crafted anti-blow out design expertly prevents the stem from being blown out, thereby safeguarding against potential damage and ensuring operational safety.

The seat ring's advanced structure, featuring a wave spring and dual-scraper, efficiently cleans the ball surface, maintaining impeccable sealing integrity and optimal performance.

Our dual-sealing technology guarantees superior leak prevention by ingeniously preventing flow from contacting the spring, ensuring unmatched leakage class standards.</sup>

Enjoy the superior sealing performance of our soft seat, renowned for its remarkable stability and reliability even under extreme conditions.

The innovative design for draining and sweeping effectively prevents valve jamming, ensuring seamless operation through comprehensive cleaning.

Built to comply with API 607 standards, our valves feature robust fire-proof and anti-static functions, providing unparalleled safety and security.
