In the demanding realm of severe services, where high temperatures and significant differential pressure present challenges, SNT's innovative multi-stage trim technology stands as a beacon of precision and durability. This exceptional design guarantees precise control and an extended lifespan, effectively eliminating issues related to cavitation erosion and noise. Regardless of whether the fluid at hand is compressive or non-compressive, this series shines with its myriad advantages. Its enhanced performance and enduring durability significantly contribute to reducing maintenance costs and simplifying system architecture. The elimination of ancillary components such as diffusers and silencers further drives down equipment expenses. Models available in 6862, 7500, and 9000 offer flexibility to choose the most suitable option based on fluid conditions, balancing functionality and cost-effectiveness.
At the heart of the multi-stage pressure-reducing labyrinth control valve is an intricately engineered core throttling component. This component, crafted from multiple stacked metal discs featuring labyrinth grooves, artfully moderates flow by channeling fluid through a series of controlled collisions and directional changes, efficiently dissipating energy and reducing pressure incrementally. This sophisticated process is ideally suited for high-temperature, high-pressure drop scenarios, such as those encountered in nuclear and power plant applications. While typically managing superheated steam, it is equally adept in handling various liquid media.
