Product Description

About products

In the demanding realms of high-temperature and high differential pressure applications, the Multi-Stage Globe Valves from SNT Machinery (Qingdao) Co., Ltd. stand out with their innovative multi-stage trim. This advanced design ensures impeccable control and significantly extends the valve's lifespan, effectively eliminating issues related to cavitation erosion and noise disturbances. Whether managing compressible or non-compressible fluids, this series offers a multitude of advantages, boasting enhanced performance and remarkable durability, which collectively lead to reduced maintenance expenses and streamlined system operation. By eliminating the need for additional components like diffusers and silencers, the equipment costs are substantially lowered. Models range from 6862, 7500, to 9000, allowing you to select the most appropriate option by comparing functionality and pricing in relation to the specific fluid conditions.

The cutting-edge multi-stage pressure-reducing labyrinth control valve features a core throttling component crafted from multiple stacked metal discs intricately designed with labyrinth grooves. As the fluid navigates these channels, it undergoes a series of energy-dissipating collisions and turns. This meticulous process ensures precise flow rate management while systematically reducing pressure, making it ideal for specialized high-temperature, high-pressure drop environments such as nuclear and power plants. While primarily used for superheated steam, it is equally effective for various liquid mediums.
