IIn the realm of severe services characterized by extreme temperatures and high differential pressures, SNT's advanced multi-stage trim offers unparalleled precision and longevity. Designed to combat cavitation erosion and eliminate noise issues, our valves deliver impeccable control, regardless of whether the fluid is compressive or non-compressive. This series is a marvel of engineering, boasting enhanced performance and durability that lead to significant maintenance cost reductions and streamlined system operations. By eliminating the need for additional components like diffusers and silencers, these valves also significantly cut down on equipment expenses. With models available in 6862, 7500, and 9000, tailored to match fluid conditions, you can select the perfect valve by balancing functionality and cost.
The sleeve-guided series of multi-stage pressure-reducing control valves revolutionizes traditional integrated throttling by transforming it into multiple, discrete throttling areas arranged in a series. This innovative design breaks down a single large pressure difference into several smaller, manageable ones. Each pressure reduction is meticulously controlled to stay above the saturation vapor pressure, thereby effectively preventing cavitation. Ideal for applications involving liquid mediums, this series stands out for its reliability and efficiency in pressure management.
