In the demanding realms of high-temperature and high-differential pressure applications, SNT Machinery's cutting-edge Varistep Cage Guided Globe Valves stand as a beacon of precision and longevity. Our meticulously engineered multi-stage trim design ensures exceptional control and durability, providing a seamless operation devoid of cavitation, erosion, and noise challenges. Whether you're dealing with compressive or non-compressive fluids, our advanced solutions offer unwavering reliability. This remarkable series boasts a myriad of advantages, with its superior performance and robust durability leading to significant maintenance cost savings and overall system streamlining. The elimination of auxiliary devices such as diffusers and silencers further contributes to cost efficiency, reducing equipment expenses. With options spanning from 6862 to 9000, the perfect model can be selected based on fluid conditions, offering an optimal balance between functionality and cost-effectiveness.
Our groundbreaking multi-stage pressure-reducing labyrinth control valve is engineered with a core throttling component composed of intricately stacked metal discs featuring labyrinth grooves. As fluid navigates through these sophisticated channels, it experiences multiple collisions and directional shifts, effectively dissipating energy. This innovative mechanism expertly manages flow rates while systematically reducing pressure, making it ideal for specialized high-temperature, high-pressure drop scenarios, such as those found in nuclear and conventional power plants. While predominantly used with superheated steam, its versatility extends to liquid mediums as well.
