IIn the demanding world of severe services involving high temperature and high differential pressure, SNT's Precision Engineered Cage Guided Multi-stage Axis Flow Control Valves excel with outstanding precision and longevity. These valves are adept at avoiding cavitation erosion and minimizing noise issues, no matter if the fluid is compressive or non-compressive. With a multitude of benefits, this series not only enhances performance and durability but also results in significant maintenance cost savings and system streamlining. The elimination of additional components like diffusers and silencers further cuts down equipment expenses. Available in models 6862, 7500, and 9000, you can choose the most suitable option by evaluating functions and prices based on fluid conditions.
The sleeve-guided series multi-stage pressure-reducing control valve revolutionizes the conventional integrated throttling area by transforming it into a series of multiple separated throttling zones. This innovative design breaks down a large pressure differential into several smaller ones, ensuring that each pressure reduction remains above the saturation vapor pressure to prevent cavitation. Ideally suited for liquid medium applications, these valves redefine efficiency in pressure control.
