Product Description
About products
IIn challenging environments characterized by extreme temperatures and high differential pressures, SNT's multi-stage trim valves offer unparalleled precision control and longevity. Experience a service free from cavitation erosion and noise, whether dealing with compressive or non-compressive fluids. These valves deliver a multitude of benefits, enhancing performance and durability while minimizing maintenance costs and simplifying systems. The need for additional components, such as diffusers and silencers, is eliminated, resulting in reduced equipment costs. With models ranging from 6862, 7500, to 9000, you can select the ideal solution tailored to your specific fluid conditions by comparing functionalities and pricing.
The sleeve-guided series of multi-stage pressure-reducing control valves ingeniously transforms a single integrated throttling area into a sequence of multiple, separated throttling zones. This innovative design breaks down a larger pressure difference into several smaller, manageable reductions, ensuring each step maintains control above the saturation vapor pressure, effectively preventing cavitation. This series excels in liquid medium applications, offering superior performance in demanding scenarios.
