Introducing the AOC-6843 series, our most advanced cage guide control valve, designed to handle large Cv values with exceptional dynamic stability. Perfectly engineered for a wide range of heavy-duty services, this series features a pressure-balanced trim ideal for managing high-pressure drops. Elevate your system's performance with the AOC-6843L//D/E series, offering control valves that excel in low noise and anti-cavitation environments. This is achieved by integrating multi-hole type cages as opposed to standard ones, within our AOC-6843 series cage guided control valves. Enjoy the convenience of interchangeable parts, with all components except the multi-hole cage being compatible with the AOC-6843 series parts. For exceptionally severe fluid conditions beyond this series, we recommend selecting our SNT LIMIPHON control type for optimal results.
