Product Description

^{Introducing the High-Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. Meticulously engineered to perfection, these valves provide outstanding Zero-Leakage performance across various high-temperature and high-pressure service environments. Our valves exemplify excellence, ensuring reliability and efficiency in every application.
Crafted with unrivaled precision, the ball and seat of these exceptional valves are reinforced with state-of-the-art hard coatings of chrome carbide or tungsten carbide. This superior fortification offers remarkable resistance to both erosion and abrasion, significantly enhancing the longevity and reliability of the valves. Experience the advantage of unparalleled durability and superior performance.
Our SNT High-Performance Soft Seated Ball Valves are enhanced with a cutting-edge HVOF coating system. Each valve is subjected to meticulous mate-lapping using proprietary techniques to ensure a flawless 100% sealing capability. The innovative live loading feature guarantees zero emissions, while the ball remains in constant, gentle contact with the seat, effectively wiping away contaminants. This pioneering self-cleaning mechanism prevents interference and potential damage from particles, making these valves the ideal choice for slurry and abrasive service applications. Trust in innovation that sets new standards of excellence.}

Structure Features

 

<sup>Our specialized packing combination is expertly engineered to achieve emission standards of 100 ppm, while simultaneously reducing stem friction by an impressive 20%.

Ingeniously designed anti-blow out feature ensures the stem remains securely in place, preventing any potential damage caused by blowouts.

The innovative seat ring structure, featuring a wave spring and dual-scraper mechanism, effectively cleans the ball surface while maintaining a robust seal.

Our advanced dual-sealing system assures the highest leakage class, cleverly designed to ensure the flow never comes into contact with the spring.</sup>

Soft seat sealing performance is engineered for exceptional stability and reliability, providing unparalleled assurance.

The efficient design of our draining and sweeping mechanism effectively prevents jamming by thoroughly cleaning the valve.

Engineered to meet API 607 standards, our valves offer outstanding fireproof and anti-static capabilities, ensuring safety and compliance.
