The AOC-6843 series represents our most cutting-edge cage guide control valve, boasting a large Cv value and exceptional dynamic stability. Perfectly engineered for a wide array of heavy-duty applications, this series excels in demanding environments. Its hallmark feature is the pressure balanced type trim, expertly crafted for managing high-pressure drops. The AOC-6843L//D/E series elevates performance by offering control valves that are specifically designed to meet rigorous low noise and anti-cavitation standards. This is accomplished through the innovative use of multi-hole type cages, surpassing the performance of traditional standard cages used in the AOC-6843 series cage guided control valves. Notably, all components, except the multi-hole cage, are seamlessly interchangeable with those in the AOC-6843 series. For extreme fluid conditions that this series cannot address, we recommend selecting the esteemed SNT LIMIPHON control type, ensuring superior performance and reliability.
