In the demanding realm of high-temperature and high differential pressure services, SNT Machinery (Qingdao) Co., Ltd. stands out with its multi-stage trim technology, offering impeccable precision in control and exceptional longevity. Our solutions expertly eliminate cavitation erosion and noise issues, ensuring a smooth operation. Whether handling compressive or non-compressive fluids, this remarkable series offers multiple advantages, enhancing performance and durability. Enjoy reduced maintenance costs and system simplification, leading to greater efficiency. With no need for additional diffusers or silencers, equipment costs are minimized as well. From models 6862, 7500, to 9000, select the most suitable option tailored to your specific fluid conditions and budget, optimizing both function and cost.
The cutting-edge multi-stage pressure-reducing labyrinth control valve utilizes a core throttling component composed of meticulously stacked metal discs with intricate labyrinth grooves. As fluids navigate these channels, energy is expertly dissipated through multiple collisions and redirections, resulting in controlled flow rates and a gradual pressure reduction. This advanced technology is perfect for high-temperature and high-pressure drop scenarios found in nuclear power and power plant applications. Primarily used with superheated steam, it is also versatile enough for liquid mediums.
