Product Description

^{Introducing the High Performance Soft Seated Ball Valve series, brought to you by the esteemed SNT Machinery (Qingdao) Co., Ltd. These valves are meticulously engineered to deliver unparalleled Zero-Leakage performance, even in the most demanding high-temperature and high-pressure service conditions.
Expertly crafted with unparalleled precision, the ball and seat of these remarkable valves are fortified with state-of-the-art hard coatings, featuring chrome carbide or tungsten carbide. This advanced reinforcement ensures these components exhibit extraordinary resistance to erosion and abrasion, significantly enhancing their longevity and performance reliability.
Our SNT High Performance Soft Seated Ball Valves are equipped with a pioneering HVOF coating system. Each valve undergoes exacting mate-lapping through proprietary methods, assuring a flawless 100% sealing capability. Moreover, the innovative live loading feature guarantees zero emissions, as the ball maintains steady contact with the seat, effectively sweeping away contaminants. This cutting-edge self-cleaning mechanism is designed to prevent interference and damage from particles, rendering these valves an ideal choice for slurry and abrasive service applications.}

Structure Features

 

<sup>The innovative special packing combination is engineered to satisfy strict emission requirements of up to 100 ppm while simultaneously reducing friction on the stem by an impressive 20%.

Our advanced anti-blowout design effectively prevents the stem from blowing out, ensuring enhanced safety and avoiding potential damage.

The meticulously crafted seat ring structure, featuring a wave spring and dual-scraper, is designed to efficiently clean the ball surface and maintain impeccable sealing.

The robust dual-sealing mechanism guarantees exceptional leakage protection by ensuring the flow does not come into contact with the spring.</sup>

The sealing performance of our soft seat is exceptionally stable and reliable, providing consistent and trustworthy operation.

Our expertly designed draining and sweeping features are essential in preventing valve jams, ensuring cleanliness and uninterrupted performance.

Compliant with API 607 standards, our valves are equipped with fire-proof and anti-static functionalities for enhanced safety and reliability.
