Product Description

^{Introducing the remarkable High Performance Soft Seated Ball Valve series by the esteemed SNT Machinery (Qingdao) Co., Ltd. These meticulously engineered marvels deliver phenomenal Zero-Leakage performance across a wide range of demanding high-temperature and high-pressure service applications.
Crafted with unparalleled precision, the ball and seat of these exceptional valves are fortified with cutting-edge hard coatings of either chrome carbide or tungsten carbide. This superior enhancement ensures extraordinary resistance to both erosion and abrasion, significantly boosting the longevity and unwavering reliability of the valves.
Our SNT High Performance Soft Seated Ball Valves feature a state-of-the-art HVOF coating system. Every valve undergoes meticulous mate-lapping using proprietary techniques to guarantee a flawless 100% sealing performance. The innovative live loading feature ensures zero emissions, with the ball continuously in contact with the seat, effectively wiping away contaminants. This advanced self-cleaning mechanism prevents interference and damage from particles, making these valves the ultimate choice for slurry and abrasive service applications.}

Structure Features

 

<sup>Our specialized packing combination is engineered to exceed industry standards by meeting the stringent emission requirement of 100 ppm. At the same time, it significantly reduces friction to the stem by an impressive 20%, ensuring smoother operation and prolonged durability.

Ingeniously crafted, the anti-blowout design is dedicated to preventing the stem from catastrophic blowout, thereby protecting the equipment from potential damage.

The innovative structure of the seat ring, incorporating wave spring and dual-scraper technology, is adept at cleaning the ball surface meticulously while maintaining impeccable sealing.

Our dual-sealing mechanism is adept at ensuring the highest leak-proof class by ingeniously preventing flow contact with the spring, guaranteeing outstanding reliability.</sup>

The performance of our soft seat sealing is crafted to deliver unparalleled stability and reliability, even under demanding conditions.

Our draining and sweeping design is meticulously crafted to prevent the valve from jamming, ensuring unobstructed operation through superior cleaning capabilities.

Designed to comply with the rigorous API 607 standards, our product is equipped with robust fire-proof and anti-static functionalities, providing unmatched safety and assurance.
