In challenging applications that demand handling high temperatures and significant differential pressure, SNT's innovative multi-stage trim ensures unparalleled precision control and exceptional longevity, eliminating the risks of cavitation erosion and noise disturbances whether you are dealing with compressive or non-compressive fluids, ensuring seamless operation in diverse conditions. This series stands out with its remarkable advantages, offering enhanced performance and robust durability that lead to substantial reductions in maintenance costs and system streamlining. With the elimination of additional components like diffusers and silencers, the equipment costs are also significantly lowered. Depending on the fluid conditions, from options 6862, 7500, to 9000, you can select the most appropriate model by comparing functionality and pricing, ensuring optimal value.
The multi-stage pressure-reducing labyrinth control valve features a core throttling component crafted from multiple layered metal discs designed with intricate labyrinth grooves. As the fluid navigates through these channels, it experiences numerous collisions and directional shifts, effectively dissipating energy. This mechanism meticulously controls flow rates while methodically reducing pressure. It proves indispensable in specialized scenarios demanding high temperature and pressure drops, such as those found in nuclear and power production plants. While predominantly used with superheated steam, it is also compatible with liquid mediums.
