Introducing the AOC-6843 Series - our latest innovation in cage guide control valves engineered for optimum performance with a large Cv value and exceptional dynamic stability. Designed for a wide array of demanding applications, this series is distinguished by its pressure-balanced trim, ideal for managing high-pressure drops seamlessly. Elevating the standard, the AOC-6843L//D/E series offers advanced control valves equipped with multi-hole type cages, expertly reducing noise and preventing cavitation compared to standard configurations. Moreover, the components, barring the multi-hole cage, are fully interchangeable with those of the AOC-6843 series, ensuring compatibility and convenience. For challenging fluid conditions beyond the scope of this range, we recommend our SNT LIMIPHON control type for unmatched performance.
