In the realm of challenging applications characterized by high temperatures and significant differential pressures, SNT's innovative multi-stage trim stands out with its promise of precise control and unparalleled longevity. Experience freedom from the typical issues of cavitation erosion and disruptive noise as our solution delivers impeccable performance. Regardless of whether the fluid in question is compressive or non-compressive, this advanced solution offers unparalleled versatility and reliability. This series boasts multiple advantages, with enhanced performance and increased durability that result in significant maintenance cost reductions and streamlined system designs. As the need for additional components like diffusers and silencers is eliminated, you benefit from a noticeable reduction in equipment costs as well. Ranging from models 6862 to 9000, depending on your specific fluid conditions, you can select the most suitable model by comparing their functionalities and pricing to perfectly match your needs.
The heart of our multi-stage pressure-reducing labyrinth control valve is its core throttling component, crafted from multiple stacked metal discs with intricate labyrinth grooves. As the fluid navigates through these channels, it undergoes a series of collisions and directional changes, effectively dissipating energy and meticulously controlling the flow rate while systematically reducing pressure. This sophisticated process finds its use in high-temperature, high-pressure drop environments, commonly within nuclear and power plant settings. While often used with superheated steam, it is equally adept at managing various liquid mediums.
