Introducing our groundbreaking AOC-6843 series, the latest innovation in cage guide control valves, designed for dynamic stability and impressive large Cv values. Perfectly engineered for an array of heavy-duty applications, it features a pressure-balanced trim to expertly manage high-pressure drops. Experience superior control with our AOC-6843L//D/E variants, which meet rigorous low noise and anti-cavitation demands through their advanced multi-hole cage design, replacing the standard cages found in the AOC-6843 series. This ensures that all non-cage components remain interchangeable with the AOC-6843 series, optimizing convenience and compatibility. For extremely demanding fluid conditions beyond this series' scope, our SNT LIMIPHON control type offers unmatched solutions.
