In challenging environments characterized by extreme temperatures and substantial differential pressures, SNT Machinery's innovative multi-stage trim offers the promise of precise control and enduring reliability. Our valves excel by eliminating issues of cavitation erosion and noise, ensuring a seamless experience. Whether your needs involve compressive or non-compressive fluids, this series stands out with its multi-faceted advantages, notably its enhanced performance and robust durability. These features lead to a significant reduction in maintenance costs and system simplification. The elimination of auxiliary equipment such as diffusers and silencers further contributes to cost efficiency, lowering equipment expenses. With options ranging from models 6862, 7500, to 9000, you can select the most suitable variant based on fluid conditions by evaluating their functions and prices.
The heart of our multi-stage pressure-reducing combined labyrinth control valve is its core throttling component, meticulously crafted from multiple stacked metal discs with intricately designed labyrinth grooves. As fluid navigates these channels, it endures numerous collisions and directional changes, efficiently dissipating energy. This sophisticated process modulates flow rates while systematically reducing pressure, ideal for specialized applications demanding high temperature and pressure management, such as in nuclear and power plant operations. While predominantly used for superheated steam, it is also versatile enough for liquid mediums.
