Product Description
About products
In the realm of severe services characterized by high temperature and substantial differential pressure, SNT's innovative multi-stage trim stands as a beacon of precision and longevity. It ensures impeccable control and an extended lifespan, all while eliminating common issues such as cavitation erosion and noise disturbances. Whether the fluid in question is compressive or non-compressive, this series offers a multitude of advantages. Its heightened performance and enduring durability not only pave the way for reduced maintenance costs but also promote system simplification. With the elimination of ancillary devices like diffusers and silencers, equipment expenses are significantly lowered. From models 6862, 7500, to 9000, based on fluid conditions, customers can select the most suitable model by comparing functions and prices, ensuring optimal performance and cost-efficiency.
The core throttling component of the multi-stage pressure-reducing labyrinth control valve is ingeniously constructed from multiple stacked metal discs, each intricately designed with labyrinth grooves. As the fluid traverses these channels, it experiences numerous collisions and directional changes, effectively dissipating energy. This sophisticated process not only manages flow rates but also incrementally reduces pressure, making it ideal for specialized high-temperature, high-pressure drop scenarios found in nuclear and power plants. While superheated steam is the predominant working medium, the valve also accommodates liquid mediums, showcasing its versatility and robust design.
