The AOC-6843 series represents our pinnacle of innovation in cage guide control valves, boasting a substantial Cv value for remarkable dynamic stability. Engineered specifically for a wide range of demanding heavy-duty applications, this series stands out with its pressure-balanced trim, designed to tackle high pressure drops with ease. The AOC-6843L//D/E series elevates control valve performance further by integrating multi-hole type cages, meticulously crafted to meet stringent low noise and anti-cavitation standards, replacing standard cages in the AOC-6843 series. Ingeniously, all components except the multi-hole cage are seamlessly interchangeable with the AOC-6843 series parts. For those exceptionally challenging fluid conditions beyond this series' capabilities, we recommend the SNT LIMIPHON control type for optimal performance.
