In challenging environments characterized by high temperatures and significant differential pressure, SNT's state-of-the-art multi-stage trim ensures precise control and exceptional longevity. With its innovative design, it eliminates the common issues of cavitation erosion and noise, providing a seamless and efficient solution for your flow regulation needs. whether the fluid is compressive or non-compressive. This series offers a multitude of benefits, including enhanced performance and durability. These features contribute to significant reductions in maintenance costs and overall system simplification. Additionally, the absence of auxiliary components such as diffusers and silencers leads to further cost savings on equipment. Models ranging from 6862 to 9000 are available, ensuring the perfect match for any fluid condition by comparing functionality and pricing.
The advanced multi-stage pressure-reducing labyrinth control valve features a core throttling component crafted from multiple layers of intricately grooved metal discs. As the fluid navigates through these labyrinthine channels, it experiences numerous collisions and directional changes, effectively dissipating energy. This sophisticated process expertly manages flow rates while methodically reducing pressure, making it ideal for high-temperature and high-pressure applications such as nuclear and power plants. While predominantly used with superheated steam, it is versatile enough for liquid mediums as well.
