Introducing the AOC-6843 series, a state-of-the-art cage guide control valve renowned for its expansive Cv value and exceptional dynamic stability. Tailored for a myriad of heavy-duty applications, this series features a pressure-balanced type trim, adeptly handling high-pressure drops. Elevate your control valve experience with the AOC-6843L//D/E series, which innovatively addresses low noise and anti-cavitation needs through its advanced multi-hole type cages, replacing the traditional cages found in the standard AOC-6843 series. Enjoy seamless compatibility as all components, aside from the multi-hole cage, are interchangeable with their counterparts in the AOC-6843 series. For particularly challenging fluid conditions beyond this series' scope, we recommend opting for the SNT LIMIPHON control type to ensure optimal performance.
