Product Description

^{Introducing the High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. Elevate your operational efficiency with these meticulously engineered valves, which deliver unparalleled Zero-Leakage performance across a vast spectrum of high-temperature and high-pressure service environments.
Crafted with unmatched precision, the ball and seat of these superior valves are fortified with advanced hard coatings of either chrome carbide or tungsten carbide. This outstanding reinforcement provides exceptional resistance to erosion and abrasion, significantly enhancing the valves' longevity and reliability, ensuring they withstand the test of time.
Our SNT High Performance Soft Seated Ball Valves are equipped with a state-of-the-art HVOF coating system. Each valve undergoes meticulous mate-lapping using proprietary techniques to ensure an impeccable 100% sealing capability. The innovative live loading feature guarantees zero emissions while keeping the ball in constant contact with the seat, effectively wiping away contaminants. This sophisticated self-cleaning mechanism prevents interference and damage from particles, establishing these valves as the ideal selection for slurry and abrasive service applications.}

Structure Features

 

<sup>A unique packing combination is engineered to meet stringent emission requirements of 100 ppm, significantly reducing stem friction by 20% for unparalleled efficiency.

Ingenious anti-blowout design effectively safeguards against stem ejection, preventing potential damage and ensuring operational safety.

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

Innovative dual-sealing technology ensures top-tier leakage protection by preventing fluid contact with the spring, thereby upholding the highest leakage class standards.</sup>

The soft seat's sealing performance is exceptionally stable and dependable, delivering consistent reliability in every application.

Strategic draining and sweeping design effectively prevents valve jamming, maintaining cleanliness and operational integrity.

Fully compliant with API 607 standards, the product offers robust fire-proof and anti-static functions, epitomizing safety and resilience.
