Introducing the AOC-6843 series, our state-of-the-art cage guide control valves, designed to excel in high-demand environments with a remarkable large Cv value and dynamic stability. Perfectly tailored for a wide array of heavy-duty applications, this exceptional series features a pressure-balanced trim, expertly engineered to handle substantial pressure drops effortlessly. The AOC-6843L//D/E series sets a new standard by incorporating multi-hole type cages, ingeniously replacing standard cages, to meet stringent low-noise and anti-cavitation requirements. Remarkably, all components, except for the multi-hole cage, are fully interchangeable with those of the AOC-6843 series, ensuring seamless compatibility. For extreme fluid conditions beyond the reach of this series, we recommend selecting the SNT LIMIPHON control type for unparalleled performance.
