Introducing the AOC-6843 series: the pinnacle of our cage guide control valves, designed for those seeking large Cv values combined with exceptional dynamic stability. Perfectly engineered for an array of heavy-duty applications, this series boasts a pressure-balanced trim tailored specifically for managing high-pressure drops seamlessly. Embrace the innovative AOC-6843L//D/E series, which redefines control valves by surpassing low noise and anti-cavitation challenges, thanks to its advanced multi-hole type cages, replacing the standard ones found in the AOC-6843 series. Ingeniously, every component, aside from the multi-hole cage, is interchangeable with the AOC-6843 series parts, offering remarkable versatility and efficiency. For those extreme fluid conditions that exceed the capabilities of this series, we recommend exploring the superior SNT LIMIPHON control type for unparalleled performance.
