Product Description

^{Introducing the cutting-edge High Performance Soft Seated Ball Valve series from SNT Machinery (Qingdao) Co., Ltd. Expertly designed and engineered to perfection, these valves offer an unprecedented Zero-Leakage performance, standing resilient in a myriad of high-temperature and high-pressure service applications.
Constructed with an unrivaled level of precision, the ball and seat within these valves are fortified with innovative hard coatings, employing chrome carbide or tungsten carbide. This exceptional layer of protection grants superior resistance to both erosion and abrasion, significantly boosting durability and dependability.
Our state-of-the-art SNT High Performance Soft Seated Ball Valves integrate a revolutionary HVOF coating system. Each valve is subjected to meticulous mate-lapping through custom techniques, ensuring an impeccable 100% sealing. The groundbreaking live loading feature guarantees zero emissions and keeps the ball in constant contact with the seat, efficiently sweeping away contaminants. This avant-garde self-cleaning mechanism averts interference and damage from particles, making these valves an ideal solution for slurry and abrasive service applications.}

Structure Features

 

<sup>Specialized packing combinations expertly meet stringent emission requirements of 100 ppm. This innovation not only ensures compliance but also remarkably reduces stem friction by 20%.

Ingenious anti-blowout design reliably prevents stem ejection, safeguarding against potential damages and ensuring operational integrity.

The seat ring architecture, featuring wave springs and dual-scrapers, efficiently cleans the ball surface and ensures impeccable sealing performance.

Our advanced dual-sealing mechanism ensures superior leakage control by strategically preventing flow contact with the spring, thus ensuring leakproof performance.</sup>

The soft seat sealing performance is characterized by its exceptional stability and reliability, offering peace of mind in demanding applications.

The innovative draining and sweeping design effectively prevents valve jamming by maintaining cleanliness throughout its operation.

Designed in strict accordance with API 607 standards, our valves offer robust fireproof and anti-static functionalities, assuring safety and dependability.
