In the demanding environments of high temperature and substantial differential pressure, SNT's multi-stage trim stands as a beacon of precision and durability. It ensures impeccable control and a prolonged lifespan, expertly eliminating issues like cavitation erosion and disruptive noise. Whether the fluid is compressible or non-compressible, this series is enhanced with numerous benefits: its superior performance and robustness lead to a decrease in maintenance costs and a simplification of system operations. The need for additional equipment, like diffusers and silencers, is eliminated, thereby reducing the overall equipment costs. Based on conditions from 6862, 7500, to 9000, the optimal model can be selected by balancing functionality and pricing, ensuring the most efficient solution.
The multi-stage pressure-reducing combined labyrinth control valve's central throttling component is ingeniously crafted with a series of stacked metal discs etched with intricate labyrinth grooves. As fluid navigates these channels, it experiences numerous collisions and directional changes, which effectively dissipate energy. This mechanism modulates flow rate and incrementally diminishes pressure, making it ideal for high temperature and high-pressure scenarios often found in nuclear and power plants. While superheated steam is the typical medium, it adapts seamlessly for liquid applications as well.
