Discover the pinnacle of innovation with SNT's High Performance Soft Seated Ball Valves, featuring a sophisticated HVOF coating system. Each valve is meticulously mate-lapped using exclusive proprietary techniques to ensure a flawless 100% sealing capability. The groundbreaking live loading system guarantees zero emissions, maintaining the ball in constant contact with the seat to efficiently wipe away contaminants. This state-of-the-art self-cleaning feature prevents any interference or damage from particles, making these valves the ideal choice for demanding slurry and abrasive service applications. Choose excellence, choose reliability, choose SNT.
A special packing combination is ingeniously designed to meet emission requirements of a remarkable 100 ppm, while simultaneously reducing stem friction by an impressive 20%. This ensures superior performance and longevity.
The innovative anti-blow out design effectively prevents the stem from blowing out, thereby protecting against potential damage and ensuring the integrity and reliability of the system.
Featuring a unique seat ring structure with a wave spring and dual-scraper, this design expertly cleans the ball surface while maintaining an impeccable seal, allowing for optimal operational efficiency.
The dual-sealing mechanism is meticulously crafted, guaranteeing excellent leakage protection by ensuring that the flow does not come into contact with the spring, thus maintaining the highest leakage class.
The soft seat sealing performance offers enhanced stability and reliability, providing consistent and dependable sealing under various conditions.
An advanced draining and sweeping design prevents the valve from becoming jammed, efficiently cleaning it to maintain smooth operation.
These valves are compliant with API 607 standards, featuring robust fire-proof and anti-static functionalities, ensuring safety and reliability even in the most demanding environments.
SNT Ball Valves are meticulously engineered to meet a wide array of international standards, including ASME B16.34-2009, ASME B16.10-2000, and API 589-2009.
