Product Description

About products

<sup>In severe service conditions involving high temperatures and significant differential pressures, SNT's advanced multi-stage trim ensures precise control and exceptional longevity, completely mitigating issues like cavitation erosion and noise, irrespective of whether the fluid is compressive or non-compressive. This remarkable series boasts multiple advantages with its enhanced performance and robust durability, leading to reduced maintenance expenses and system simplification. The elimination of ancillary equipment like diffusers and silencers further slashes equipment costs. With models ranging from 6862, 7500, to 9000, depending on fluid conditions, the most suitable model can be selected by comparing functions and prices.

The innovative sleeve-guided series multi-stage pressure-reducing control valve reimagines the traditional integrated throttling area by transforming it into multiple distinct throttling sections in series. This ingenious design effectively breaks down a large pressure difference into several smaller ones, ensuring that each pressure reduction is maintained above the saturation vapor pressure, thereby preventing cavitation. It is predominantly applied in scenarios involving liquid medium operations.</sup>
