The AOC-6843 series proudly stands as our cutting-edge cage guided control valve, designed for substantial Cv value and exceptional dynamic stability. Engineered to tackle various heavy-duty applications, this series boasts a remarkable pressure balanced type trim, perfect for enduring high-pressure drops. The AOC-6843L//D/E series elevates control valves to new heights by addressing low noise and anti-cavitation challenges, accomplished through innovative multi-hole type cages, replacing standard cages, within the AOC-6843 series. Importantly, all components, excluding the multi-hole cage, are fully interchangeable with parts from the AOC-6843 series. For conditions that exceed the capabilities of this series, we recommend selecting the SNT LIMIPHON control type, tailored for the most severe fluid conditions.
