In the realm of severe service conditions characterized by high temperature and significant differential pressure, SNT's multi-stage trim ensures precise control and extended longevity, completely eliminating issues like cavitation erosion and noise disturbances. Regardless of whether the fluid is compressive or non-compressive, this series stands out for its remarkable advantages, offering enhanced performance and durability which contribute to significant maintenance cost savings and system simplification. With the elimination of the need for ancillary components like diffusers and silencers, equipment costs are also minimized. Models ranging from 6862, 7500, to 9000 are available, allowing for the selection of the most suitable option based on fluid conditions, comparing both functionalities and pricing.
The core throttling component of our multi-stage pressure-reducing combined labyrinth control valve is ingeniously designed with multiple stacked metal discs featuring labyrinth grooves. As fluid navigates through these channels, it experiences repeated collisions and turns, effectively dissipating energy. This sophisticated process expertly controls flow rate while methodically reducing pressure, making it ideally suited for specialized high temperature and high-pressure drop scenarios, such as those found in nuclear power and power plants. While it predominantly handles superheated steam, it is equally adept with liquid mediums.
