Product Description

About products

In the realm of severe services characterized by high temperature and significant differential pressure, SNT Machinery (Qingdao) Co., Ltd. presents the Efficient Cage Guided Multi-stage Limiphon Control Valves. Our state-of-the-art multi-stage trim delivers precise control and ensures exceptional longevity, effectively eliminating challenges like cavitation erosion and noise disturbances. No matter if the fluid is compressive or non-compressive, our valves provide unparalleled performance and adaptability. This series boasts multiple advantages. Enhanced performance and remarkable durability not only contribute to reduced maintenance costs but also facilitate system simplification. The elimination of additional components such as diffusers and silencers further leads to lowered equipment costs. Depending on the fluid condition, choose from models 6862, 7500, or 9000, selecting the optimal solution by comparing functionality and price.

The heart of our multi-stage pressure-reducing labyrinth control valve is its innovative design, featuring multiple stacked metal discs with intricate labyrinth grooves. As fluid navigates through these channels, it experiences multiple collisions and turns, effectively dissipating energy. This meticulous process not only regulates the flow rate but also incrementally reduces pressure, making it ideal for high-temperature and high-pressure drop environments, such as nuclear and power plants. Primarily handling superheated steam, our valves are also versatile enough for liquid mediums.
