Introducing the esteemed AOC-6843 series, a marvel in the realm of cage guide control valves, renowned for its remarkable large Cv value and extraordinary dynamic stability. Engineered to excel in the most demanding of heavy-duty applications, this series boasts a pressure-balanced trim, meticulously designed for handling high-pressure drops with ease. The AOC-6843L//D/E variants elevate control valve performance to new heights, seamlessly integrating low-noise and anti-cavitation features through the innovative use of multi-hole type cages, replacing standard options. Remarkably, all components, with the exception of the multi-hole cage, are interchangeable with those in the AOC-6843 series, ensuring flexibility and convenience. For fluid conditions of exceptional severity that stretch beyond this series' capabilities, we recommend the SNT LIMIPHON control type for unmatched performance.
