Product Description
About products
In the demanding realm of severe services characterized by extreme temperatures and high differential pressures, SNT's sophisticated multi-stage trim delivers unmatched precision in control and exceptional longevity. Say goodbye to cavitation erosion and noise issues with this remarkable solution. Whether your fluid needs are compressive or non-compressive, this series offers a multitude of advantages. Its enhanced performance and robust durability significantly lower maintenance expenses and streamline your system. With the elimination of additional components like diffusers and silencers, you'll find a noticeable reduction in equipment costs. With models available in 6862, 7500, and 9000 series, you can select the optimal option by comparing both functionality and pricing, tailored to your specific fluid conditions.
The multi-stage pressure-reducing combined labyrinth control valve features a core throttling component crafted from multiple stacked metal discs embedded with labyrinth grooves. This intricate design ensures the fluid engages in numerous collisions and directional shifts as it traverses the channels, effectively dissipating energy. This intricate mechanism precisely regulates flow rate while gradually lowering pressure, making it ideal for specialized high-temperature and high-pressure drop scenarios, such as those found in nuclear and power plants. While primarily used with superheated steam, it is also suitable for various liquid mediums.
