Product Description

^{Introducing the exceptional High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. Crafted with meticulous attention to detail, these valves promise unrivaled Zero-Leakage effectiveness, making them indispensable in a spectrum of high-temperature and high-pressure service applications.
Masterfully crafted with precision, the ball and seat of these valves are fortified with sophisticated hard coatings of chrome carbide or tungsten carbide. This remarkable enhancement ensures unparalleled resistance to both erosion and abrasion, significantly boosting the valves' longevity and reliability.
Our SNT High Performance Soft Seated Ball Valves feature a cutting-edge HVOF coating system. Each valve is meticulously mate-lapped using proprietary techniques to ensure a perfect 100% sealing capability. The advanced live loading feature guarantees zero emissions, while the ball consistently maintains contact with the seat, efficiently sweeping away contaminants. This innovative self-cleaning function prevents interference and damage from particles, making these valves an ideal choice for slurry and abrasive service applications.}

Structure Features

 

<sup>Our special packing combination is meticulously engineered to meet strict emission requirements of 100 ppm, while simultaneously reducing friction to the stem by an impressive 20%.

Ingeniously designed with an anti-blowout feature, our product effectively prevents stem ejection, safeguarding against potential damage.

The seat ring structure, featuring a wave spring and dual-scraper design, expertly cleans the ball surface to maintain optimal sealing integrity.

Our dual-sealing technology guarantees superior leak prevention by ensuring that the flow remains isolated from the spring, achieving excellent leakage class.</sup>

Engineered for excellence, the sealing performance of our soft seat is exceptionally stable and reliably enduring.

Our advanced draining and sweeping design effectively prevents the valve from jamming, maintaining cleanliness and operational efficiency.

Fully compliant with API 607 standards, our product boasts robust fire-proof and anti-static capabilities, ensuring unmatched safety and reliability.
