Product Description

About products

In the realm of severe service applications marked by high temperatures and substantial differential pressures, SNT's exceptional multi-stage trim is your beacon of precision control and longevity. It bravely stands against cavitation erosion and noise concerns, ensuring your operations remain smooth and efficient. Whether dealing with compressive or non-compressive fluids, this advanced system boasts multi-faceted advantages. Its enhanced performance and robust durability contribute to significant maintenance cost savings and streamline system operations, eliminating the need for additional components such as diffusers and silencers. This translates to reduced equipment costs. Models range from 6862, 7500, to 9000, allowing you to choose the most suitable option based on fluid conditions, balancing functionality and budget.

At the heart of this innovative multi-stage pressure-reducing labyrinth control valve lies a sophisticated throttling component crafted from multiple stacked metal discs adorned with intricate labyrinth grooves. As fluid navigates these channels, it engages in multiple collisions and turns, effectively dissipating energy. This meticulous process not only regulates the flow rate but also progressively curtails pressure, making it ideal for high-temperature, high-pressure drop scenarios such as those found in nuclear and power plants. While predominantly used with superheated steam, its versatility extends to liquid mediums as well.
