The AOC-6843 series represents the pinnacle of our latest advancements in cage guide control valves, designed with a focus on large Cv values and dynamic stability for unparalleled performance in demanding heavy-duty applications. This exceptional series boasts a pressure-balanced trim type, specifically engineered to handle high-pressure drops effortlessly. The AOC-6843L/D/E series goes a step further by offering control valves that are meticulously crafted to meet stringent low noise and anti-cavitation requirements, thanks to the incorporation of innovative multi-hole type cages-setting a new standard above the conventional cages found in the AOC-6843 series. Remarkably, all parts with the exception of the multi-hole cage are fully interchangeable with those of the AOC-6843 series, ensuring seamless integration and versatility. For the most challenging fluid conditions beyond the reach of this series, SNT LIMIPHON control type is the recommended alternative, offering superior adaptability and control.
