In the demanding realm of severe services, characterized by high temperature and elevated differential pressure, SNT's state-of-the-art multi-stage trim is your solution for impeccable control and unmatched longevity. Designed to operate free from the usual troubles of cavitation erosion and disruptive noise, this product assures seamless performance, whether managing compressive or non-compressive fluids. This series boasts a multitude of advantages, enhancing both performance and durability. These enhancements translate into significant reductions in maintenance costs and overall system simplification. With the obsolescence of additional components such as diffusers and silencers, equipment costs are also notably diminished. From models 6862, 7500, to 9000, each is tailored to suit specific fluid conditions, allowing for an optimal selection that balances functionality and cost.
The multi-stage pressure-reducing labyrinth control valve features an innovative core throttling component, crafted from multiple stacked metal discs embedded with intricate labyrinth grooves. As the fluid navigates through these channels, it experiences numerous redirections and collisions, effectively dissipating energy to control flow rates while methodically reducing pressure. This advanced technology is ideal for specialized applications with extreme temperatures and significant pressure fluctuations, such as in nuclear power and conventional power plants. While predominantly used with superheated steam, it is equally adept when employed with various liquid mediums.
