Experience unmatched performance in extreme conditions with SNT's High Pressure Drops Control Valves, featuring advanced Varistep Cage Technology. In environments with high temperatures and significant differential pressures, our innovative multi-stage trim confidently delivers precision control and exceptional longevity, effectively eliminating issues related to cavitation erosion and noise. Whether dealing with compressive or non-compressive fluids, this versatile series stands out due to its enhanced performance and robust durability, which significantly reduces maintenance costs and streamlines your system. With the elimination of ancillary equipment such as diffusers and silencers, overall equipment costs are also minimized. Available in models 6862, 7500, and 9000, you can select the most suitable option by comparing functions and pricing based on specific fluid conditions.
Our multi-stage pressure-reducing labyrinth control valve features a core throttling component crafted from multiple stacked metal discs with intricate labyrinth grooves. As the fluid navigates through these channels, it experiences multiple collisions and turns, effectively dissipating energy and controlling flow rate while gradually reducing pressure. This technology is ideal for specialized scenarios involving high temperatures and pressure drops, such as in nuclear and power plants, handling superheated steam and various liquid mediums with precision.
