Introducing the AOC-6843 Series, our cutting-edge cage guide control valves engineered for excellence in high-performance applications. With an impressive large Cv value and dynamic stability, this series is the perfect solution for a range of heavy-duty services. The AOC-6843 stands out with its pressure-balanced trim, expertly designed to handle high-pressure drops with ease. The AOC-6843L//D/E series takes this a step further by addressing low noise and anti-cavitation requirements-thanks to the integration of advanced multi-hole type cages, as opposed to the standard cages found in the original AOC-6843 series. This innovation ensures that all parts, except for the multi-hole cage, seamlessly interchange with components of the AOC-6843 series. For extremely challenging fluid conditions where this series might not suffice, we recommend opting for the SNT LIMIPHON control type for unmatched performance.
