Product Description
About products
In the demanding realms of high temperature and high differential pressure conditions, SNT's multi-stage trim delivers unparalleled precision and enduring reliability. Our product excels by eliminating cavitation erosion and significantly reducing noise levels, ensuring a robust and efficient operation. Whether you are working with compressible or non-compressible fluids, this series offers a multitude of benefits. Its enhanced performance and robust durability not only minimize maintenance expenses but also streamline system design, as additional components like diffusers and silencers are rendered unnecessary. This leads to a considerable reduction in equipment costs. With models ranging from 6862, 7500, to 9000, tailored to various fluid conditions, customers can select the most appropriate model by evaluating both functionalities and costs.
The sophisticated multi-stage pressure-reducing labyrinth control valve features a core throttling element made up of numerous layered metal discs intricately etched with labyrinth pathways. As the fluid navigates these channels, it undergoes multiple directional changes and energy dissipations. This meticulous process not only regulates the flow rate but also gradually reduces pressure. It's especially suitable for challenging environments with extreme temperature and pressure drops, commonly used in industries like nuclear power and conventional power plants. While it primarily handles superheated steam, it is also adaptable to liquid mediums.
