In the demanding environments characterized by extreme high temperatures and significant differential pressures, SNT's multi-stage trim offers unparalleled precision control and longevity. Our solutions eliminate concerns of cavitation erosion and noise, regardless of whether the fluid is compressive or non-compressive. This series stands out due to its enhanced performance and robust durability, leading to reduced maintenance costs and streamlined system operations. By eliminating the need for additional components like diffusers and silencers, we also offer significant equipment cost savings. Depending on the fluid conditions, you can choose the most suitable model from our range of 6862, 7500, and 9000, comparing both functionality and cost-efficiency.
The sleeve-guided series of multi-stage pressure-reducing control valves innovatively transforms an originally singular throttling area into multiple, sequentially separated throttling areas. This ingenious design converts a substantial pressure difference into several manageable smaller differences. By ensuring every pressure reduction remains above the saturation vapor pressure, we effectively prevent cavitation. This series is optimally designed for liquid medium applications, delivering exceptional performance in demanding scenarios.
