Product Description

About products

In the realm of severe service applications characterized by high temperatures and substantial differential pressures, SNT's Advanced Cage Guided Multi-stage Limiphon Control Valves stand as a pinnacle of engineering excellence. Our meticulously designed multi-stage trim ensures precise control, delivering longevity and a flawless operation devoid of cavitation erosion and noise disturbances. This unwavering reliability is maintained regardless of whether the fluid is compressive or non-compressive, showcasing its versatile adaptability. This series is replete with advantages; its superior performance and robustness contribute to a significant reduction in maintenance costs and system streamlining. By eliminating the need for supplementary components such as diffusers and silencers, we effectively minimize equipment expenses. With options available in 6862, 7500, and 9000 models, each carefully selected based on fluid conditions, customers can compare functionalities and pricing to identify the most suitable solution.

The core of our multi-stage pressure-reducing labyrinth control valve is a sophisticated assembly of stacked metal discs featuring intricate labyrinth grooves. As fluid traverses these labyrinthine pathways, it engages in multiple collisions and directional changes, dispersing energy efficiently. This design not only regulates flow rates but also methodically decreases pressure, making it an ideal choice for high-stakes environments like nuclear and power plants. Predominantly used with superheated steam, our valves are equally adept at handling liquid mediums, ensuring unmatched versatility and reliability.
