Product Description
About products
In challenging environments characterized by high temperatures and significant pressure differences, SNT's advanced multi-stage trim offers precise control, extended longevity, and is immune to cavitation erosion and noise disturbances. Whether handling compressive or non-compressive fluids, this series stands out with its superior performance and robustness, facilitating a noteworthy reduction in maintenance expenses and system streamlining. As auxiliary components like diffusers and silencers become unnecessary, overall equipment costs diminish. Depending on specific fluid conditions, from 6862, 7500, to 9000, the most fitting model can be selected by evaluating functionality and pricing.
The ingenious multi-stage pressure-reducing labyrinth control valve features a core throttling component made of multiple stacked metal discs etched with labyrinth grooves. As the fluid navigates through these intricate channels, it experiences numerous collisions and directional changes, effectively dissipating energy. This mechanism delicately manages flow rates while gradually lowering pressure. This valve is predominantly utilized in specialized high-temperature, high-pressure drop scenarios, such as those found in nuclear and power plants. Although primarily used for superheated steam, it is equally adept at handling liquid mediums.
