Product Description

^{Introducing the High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. These meticulously engineered valves are the epitome of precision and excellence, designed to deliver unparalleled Zero-Leakage performance across a spectrum of high-temperature and high-pressure service applications.
Crafted with meticulous precision, the ball and seat of these valves are fortified with revolutionary hard coatings of chrome carbide or tungsten carbide. This extraordinary reinforcement provides superior resistance to both erosion and abrasion, significantly enhancing the longevity and reliability of the valves.
Our SNT High Performance Soft Seated Ball Valves are enhanced with a cutting-edge HVOF coating system. Each valve undergoes precise mate-lapping using exclusive proprietary techniques to ensure impeccable 100% sealing. The innovative live loading feature guarantees zero emissions, while ensuring the ball remains in constant contact with the seat to effectively wipe away contaminants. This advanced self-cleaning mechanism prevents interference and damage from particles, making these valves the ideal choice for slurry and abrasive service applications.}

Structure Features

 

<sup>Our innovative special packing combinations are engineered to meet stringent emission requirements of 100 ppm, all while reducing stem friction by an impressive 20%.

With an advanced anti-blowout design, our valves are crafted to prevent stem blowouts and protect against potential damage, ensuring enduring durability.

The seat ring, designed with a wave spring and dual-scraper, effectively cleans the ball surface, ensuring a pristine environment for optimal sealing.

Featuring dual-sealing capabilities, our valves ensure superior leakage prevention by isolating the spring from flow contact, maintaining exceptional performance.</sup>

Experience the unmatched stability and reliability of our soft seat sealing performance, crafted for consistent and precise operation.

Our expertly designed draining and sweeping mechanisms effectively prevent valve jamming, promoting seamless and efficient operations.

Engineered in compliance with API 607 standards, these valves boast fireproof and anti-static functionalities for ultimate safety and reliability.
