Product Description

About products

When it comes to the rigorous demands of high-temperature and high differential pressure services, SNT Machinery (Qingdao) Co., Ltd. offers a remarkable solution with its Low Maintenance Cage Guided Multi-stage Limiphon Control Valves. Developed for precise accuracy and unrivaled longevity, these valves combat cavitation erosion and eliminate noise issues effortlessly. whether the fluid is compressive or non-compressive. This series stands out with its multitude of advantages, primarily due to its enhanced performance and robust durability. These features significantly slash maintenance costs and lead to system simplification. The elimination of ancillary components like diffusers and silencers reduces overall equipment costs as well. Depending on the fluid conditions, models 6862, 7500, and 9000 can be selected to best suit your needs, offering a perfect blend of functionality and cost-efficiency.

The multi-stage pressure-reducing combined labyrinth control valve incorporates a unique core throttling mechanism made from numerous stacked metal discs embedded with labyrinth grooves. As the fluid navigates through these intricate channels, it experiences multiple collisions and redirections, effectively dissipating energy to control flow rate while systematically lessening pressure. This sophisticated process is indispensable in high temperature and high-pressure environments, such as nuclear and power plants. While often handling superheated steam, it is equally adept at managing liquid mediums.
