Introducing the AOC-6843 series, our premier cage guide control valve engineered for optimal performance with large Cv values and exceptional dynamic stability. Perfectly designed for a diverse range of heavy-duty applications, this series stands out with its pressure-balanced type trim, expertly crafted for high-pressure drop scenarios. The AOC-6843L//D/E series elevates your control valve experience by seamlessly integrating multi-hole type cages, setting new standards in low noise and anti-cavitation performance, as a superior alternative to the standard cages found in the AOC-6843 series. Remarkably, all components, excluding the multi-hole cage, are fully interchangeable with the parts of the AOC-6843 series, ensuring versatility and convenience. For those challenging fluid conditions beyond the scope of this series, we recommend the exceptional SNT LIMIPHON control type for unparalleled results.
