Product Description

About products

In the most demanding high-temperature and high differential pressure applications, SNT's state-of-the-art multi-stage trim offers precise control and exceptional longevity. It operates free from the typical challenges of cavitation erosion and noise disturbances, ensuring a reliable and smooth performance. Whether dealing with compressive or non-compressive fluids, this series stands out with its multi-faceted advantages. Enhanced performance and durability not only lead to reduced maintenance costs but also enable system simplification. By eliminating the need for additional equipment such as diffusers and silencers, the overall equipment investment is minimized. With models 6862, 7500, and 9000 available, clients can choose the most suitable option based on specific fluid conditions, comparing both functionality and cost.

The remarkable multi-stage pressure-reducing labyrinth control valve features a core throttling mechanism made of multiple layered metal discs with intricate labyrinth grooves. As fluid navigates these complex paths, it experiences numerous collisions and directional changes, effectively dissipating energy. This sophisticated process manages the flow rate and systematically reduces pressure, making it ideal for high-temperature, high-pressure drop environments like nuclear and power plants. While primarily used with superheated steam, it is also adaptable to various liquid mediums.
