The AOC-6843 series represents the pinnacle of our latest engineering innovation in cage guide control valves, boasting a large Cv value and exceptional dynamic stability. This cutting-edge series is meticulously crafted to excel in a diverse range of demanding, heavy-duty applications. A hallmark feature of this series is its pressure-balanced trim, expertly designed to accommodate high-pressure drops with ease. The AOC-6843L//D/E series elevates performance by integrating advanced multi-hole type cages, deftly addressing low noise and anti-cavitation demands, a notable upgrade from the standard cages of the AOC-6843 series. Impressively, all components, excluding the multi-hole cage, are fully interchangeable with the standard AOC-6843 series parts, ensuring seamless integration. For fluid conditions of extreme severity beyond the scope of this series, we recommend choosing the SNT LIMIPHON control type for optimal results.
