In the realm of demanding industrial applications, where high temperatures and significant differential pressures are prevalent, SNT Machinery (Qingdao) Co., Ltd.'s ANSI Class 150-2500 Cage Guided Globe Valves stand out with their unmatched prowess. Our multi-stage trim technology is engineered to deliver precise control and ensure extended longevity, effectively eliminating challenges related to cavitation erosion and noise disturbances. Whether your fluid type is compressive or non-compressive, our expertly designed valves are equipped to handle it all. This series distinguishes itself through its multitude of benefits, including enhanced performance and durability, which contribute to reduced maintenance costs and overall system simplification. With the elimination of additional components like diffusers and silencers, the total equipment cost sees a significant reduction. From models 6862 to 7500 and 9000, depending on the specific fluid conditions, you can select the most appropriate model by evaluating both functions and pricing.
The innovative multi-stage pressure-reducing labyrinth control valve features a core throttling component composed of intricately stacked metal discs etched with labyrinthine grooves. As the fluid traverses these elaborate channels, it undergoes successive collisions and directional shifts, effectively dissipating energy. This mechanism adeptly manages flow rates and gradually diminishes pressure, making it indispensable in specialized high-temperature and high-pressure environments, such as those found in nuclear and conventional power plants. While predominantly applied with superheated steam, it also accommodates liquid mediums with remarkable efficiency.
