Introducing the AOC-6843 series, the pinnacle of our latest cage guide control valve technology, designed for applications demanding large Cv values and exceptional dynamic stability. Perfect for a myriad of heavy-duty applications, this series stands out with its pressure-balanced trim, adeptly managing high-pressure drops. A hallmark of the AOC-6843L//D/E series is its innovative multi-hole type cages, crafted to address low noise and anti-cavitation needs more effectively than standard cages. Impressively, all components, save for the multi-hole cage, are fully interchangeable with the standard AOC-6843 series, ensuring seamless integration and versatility. For extreme fluid conditions beyond this series' capabilities, opt for the SNT LIMIPHON control type, promising unparalleled performance.
