The AOC-6843 series represents the pinnacle of innovation in our lineup, featuring cage guide control valves with an impressively large Cv value, ensuring dynamic stability even in the most demanding industrial applications. These valves are meticulously engineered for a diverse range of heavy-duty services and are distinguished by their pressure-balanced trim, expertly designed to manage high-pressure drops with ease. The AOC-6843L//D/E series takes performance a step further by integrating multi-hole type cages, tailored specifically to address stringent low noise and anti-cavitation requirements, making them superior to the conventional cages found in the standard AOC-6843 series. Notably, all components, apart from the advanced multi-hole cage, maintain full interchangeability with those of the AOC-6843 series. For environments with exceptionally challenging fluid conditions that exceed the capabilities of this series, we recommend opting for the SNT LIMIPHON control type, ensuring optimal performance in every situation.
