Introducing the AOC-6843 series, our cutting-edge cage guide control valve specifically engineered with a large Cv value for unparalleled dynamic stability. Perfectly crafted for an array of heavy-duty applications, this series boasts a pressure-balanced trim, expertly designed to handle high-pressure drops with ease. For scenarios demanding low noise and anti-cavitation properties, the AOC-6843L//D/E series elevates performance by integrating innovative multi-hole type cages, seamlessly replacing the standard cages found in the AOC-6843 series cage guided control valves. Remarkably, all components, except for the specialized multi-hole cage, are fully interchangeable with parts from the AOC-6843 series, ensuring convenience and flexibility. For exceptionally challenging fluid conditions beyond the scope of this series, we recommend choosing the SNT LIMIPHON control type for superior results.
