Expertly designed and meticulously engineered, these top-tier valves ensure exceptional Zero-Leakage performance in a wide array of challenging high-temperature and high-pressure service applications. Trust in our superior craftsmanship for unparalleled excellence.
Crafted with unparalleled precision, the ball and seat components of these exceptional valves are strengthened with sophisticated hard coatings of chrome carbide or tungsten carbide. This superior fortification ensures extraordinary resistance to erosion and abrasion, significantly enhancing the durability and reliability of each valve. Rely on this advanced engineering for long-lasting performance.
Our SNT High Performance Soft Seated Ball Valves feature an advanced HVOF coating system, pushing the boundaries of innovation. Every valve undergoes meticulous mate-lapping through proprietary techniques to ensure a flawless 100% sealing capability. The groundbreaking live loading feature guarantees zero emissions, while maintaining the ball's constant contact with the seat. This design effectively wipes away contaminants, creating a revolutionary self-cleaning mechanism that prevents interference and damage from particles. These valves are the ideal choice for slurry and abrasive service applications, offering the ultimate in reliability and performance.}

Structure Features

 

<sup>Our innovative special packing combination not only meets the stringent emission requirements of 100 ppm but also reduces friction by a remarkable 20% for the stem.

Our state-of-the-art anti-blowout design ensures that the stem remains intact, preventing any potential damage from blowouts.

Featuring an advanced seat ring structure with wave spring and dual-scraper design, our product effectively cleans the ball surface and maintains impeccable sealing.

The dual-sealing technology guarantees superior leakage class by effectively isolating the flow from contact with the spring.</sup>

Experience enhanced reliability with our soft seat's stable and dependable sealing performance.

Our innovative draining and sweeping design actively prevents the valve from jamming by ensuring thorough cleaning.

Engineered to comply with API 607 standards, our valves boast fire-proof and anti-static functionalities for optimal safety.
