Product Description

 

Introducing a series of Soft Seated Ball Valves that promise absolute Zero-Leakage performance in diverse service applications, even under high-temperature and high-pressure conditions. This product is engineered to meet the stringent demands of industrial settings where reliability and precision are paramount.
The ball and seat are fortified with advanced hard coatings, utilizing either chrome carbide or tungsten carbide. These coatings offer exceptional resistance to erosion and abrasion, ensuring long-lasting durability and consistent performance.
SNT Machinery employs the cutting-edge HVOF coating system, combined with proprietary mate-lapping techniques, to guarantee perfect sealing at all times. Our innovative live loading mechanism ensures zero emissions, guaranteeing eco-friendly operation. The ball remains seated, effectively sweeping away contaminants, a self-cleaning mechanism that prevents interference and damage. This makes our valve ideally suited for both slurry and abrasive service applications, delivering unmatched durability and efficiency.

Structural Features

 

Our expertly crafted special packing combination not only meets the stringent emission requirements of 100 ppm but also significantly reduces friction by 20% at the stem, ensuring smoother operations.

1. The innovative anti-blowout design effectively prevents the stem from blowing out, thereby safeguarding the entire mechanism from potential damage.

2. The seat ring's advanced structure, featuring both a wave spring and dual-scraper, works tirelessly to cleanse the ball surface while maintaining impeccable sealing.

3. Our dual-sealing mechanism ensures superior leakage protection by meticulously isolating the flow from the contact spring, guaranteeing top-notch leakage class.

4. Experience enhanced stability and reliability with the sealing performance of our cutting-edge soft seat.

5. The ingenious design of draining and sweeping functions effectively prevents the valve from becoming jammed, ensuring optimal cleanliness and functionality.

6. Fully compliant with the rigorous API 607 standards, our valve boasts robust fire-proof and anti-static functionalities.
